KADE-compatible AVR vendors reference list
« on: September 29, 2014, 09:44:58 pm »
This thread is the result of spending WAY too much time chasing down threads and links every time someone asks where to buy KADE-compatible AVRs and hardware.

    miniArcade/microArcade
Keyboard, gamepad, and optical (spinner/trackball) firmwares available in KADE Loader.
atmega32u2 (or at90usb162)

Interesting, PJRC's board is not compatible? Why is that?

Not that I use PJRC much (I prefer MattairTech) because I hate fussing with his bootloader. I'd feel more comfortable if I knew what was running under the hood there.

I just ask because everyone seems to like dry humping his boards second to the damn Arduino lineup.

Not familiar with PJRC, but based on the fact that they carry Teensy boards, I'd guess that they use the Arduino bootloader.  :dunno

The current version of  KADE Loader doesn't work with Arduino bootloader, but it's on the team's list of things to do.

The microArcade/miniArcade use the Atmel bootloader which is compatible with the current version of KADE Loader.

KADESTICK also uses the Atmel bootloader, but you have to use FLIP to program it since Loader hasn't been updated to recognize the MattairTech board yet.

If there's a good tutorial showing how to load hex files to boards with Arduino bootloaders, I'd love to try it.

I picked up a generic Pro Micro several months ago to use as a KADESTICK, but still haven't figured out how to load hex files on it like Jon managed to on his.   :banghead:  :dizzy:

I should have bought more at the $5 price point.  I just started teaching my kid how to program the things and I expect her to blow up a couple.  :(

IIRC PJRC doesn't use the Arduino bootloader though I believe he does offer a library for compatibility. The teensy uses a proprietary bootloader (at least on the AVR line) called Halfkay which forces one to use his tools when uploading.

It's an amazing piece of work really. Problem is is that the hex, bin or source is not readily available and he sets his fuse bits to prevent retrieving the binaries. Fair enough, I can play it that way. However, he doesn't like other developers from integrating his communication protocol into their tools. After a bit of research I discovered he has a history of not allowing other developers access to that protocol in their tools. If you want to upload to a Teensy, you need the Teensy tools.

I think he did allow others to use his protocol at one point but he's pulled those permissions. Not sure if any of that changed in recent years. So you might want to look into that.

Based on that, I don't expect the KADE team will be interested in pursuing the Teensy.   :dunno

IMHO it doesn't make sense to pursue an alternate board that is more expensive and more restrictive than what they are using now.

If someone does come up with a way to load KADE hex files onto another board, I'd be happy to add links to a good tutorial and vendors -- especially for the Pro Micro.   ;D

I'm going to purchase 5 - 7 minimus AVRs. I see that there's a 32k version (atmega32u2) and a 16k version (at90usb162). Is the only difference between the two of them the amount of memory? Since both work with Kade is there any benefit to paying more for the 32k version?

There is no advantage to using one version over the other for KADE, but the 32k boards are easier to find.

The 16k boards already sold out AFAIK -- let us know if you have a source that's not listed in the OP. (after you place your order)   ;D

Hmmm... I saw both versions at foundmy.com. The title for each version includes the words "In Stock", but apparently the 16k is not in stock. It was only a $2 difference anyway. So I'll be testing my soldering skills soon. It's been a while since I've soldered 2.54mm screw terminals...

Not a bad deal at $11 a pop for the 32U2, but their "regular" price is insane.

Not too many good reviews for the site either.

I attempted to place an order at foundmy.com a few weeks ago. The website didn't take credit cards. Instead they were supposed to call and take my info over the the phone. Needless to say, they never called and I wouldn't have completed the order if they did. So I don't know if they belong on the list.

I ended up getting mine from the ck3 site. I got 10 for $99 (inc shipping) from the UK to the US. I also got some 12 pole screw terminals from ebay for about $1.50 each. They all arrived in less than two weeks so now it's time for some soldering!

Not many vendors left for Minimus AVRs -- just ck3.co.uk and KADE encoders/kits from the KADE store AFAIK.  :(

I suspect that the KADE team will eventually come up with some sort of alternative hardware.

They'll probably do that after they (finally!!) finish shipping the miniConsole+ Kickstarter rewards in May . . . 2018.  jk   :duckhunt

I did too. And even gave one of my spares to MGB for his project.

I have only a couple left but thought I'd look around for more since they were so cheap. Two are currently connected to my Xbox classic. :-)

I thought they had the other day when reading Nitz's post ( http://forum.arcadecontrols.com/index.php/topic,150185.msg1568955.html#msg1568955 ) but looks like it is another competing product instead and not from the Kade team. It looked promising but looks like it was only a small run for testing so is likely to be just as hard to get and at $25 doesn't really offer the ability to cheap out and just buy the minimus portion like the Kade does.

Wonder what it would cost per unit to have a small order of the minimus produced - If we could get enough interest in purchasing some ? - The $20 postage from ck3.uk kind of defeats the price advantage of just getting the minimus unless you order several  :dunno

An Arduino uno clone is about 6 bucks.  If you want to go high end, a teensy 3.0 is around 15-20.  Both options are readily available and are powerful enough to handle most console controllers.  The problem is software.... I was going to work on it but was politely told where to go so I'm not bothering.  AVR programming is easy though... most of your classic gamepads can be handled pretty easily if you are willing to invest the time in learning how. 

I wish everyone luck.

Yeah . . . nitz76 hasn't exactly earned a lot of love from the KADE team.

PROS:
- Designed an AVR board with supporting components.

CONS:
- Was using KADE logos/images/links. (he took most of them down when asked) Remaining images removed when they were pointed out
- Is still using Jon's animated LED demo .gif in his post and in his ebay ad. Image removed when it was pointed out
- His post includes the phrase "give some feedback like a led or a rumble." which implies an LEDBlinky-style feature that neither the LED demo firmware nor any other miniArcade firmware currently has.
- His post states "Open source design. (Public domain)." but AFAIK he hasn't released his board files and Bill of Materials -- not on his site and not on KADE's Github.
- So far, no stated plans on how he intends to provide customer support for his product.

A better example of 3rd party hardware development is silverfox0786.

He designed and built some KADE compatible rotary joystick adapter boards here.



Wonder what it would cost per unit to have a small order of the minimus produced - If we could get enough interest in purchasing some ? - The $20 postage from ck3.uk kind of defeats the price advantage of just getting the minimus unless you order several  :dunno
Two problems:

1. Getting permission from the Minimus' designer to use the board design and parts list.

2. Any small run order would be prohibitively expensive and time consuming.

Unless another cheap alternative is found, it seems like a better idea to just design a new AVR board using newer hardware.   :dunno

Based on a quick glance, the KADESTICK's ATMega32u4 chip only costs a few dollars more than the miniArcade's ATMega32u2 chip and the 32u4 has analog (potentiometer) input capability.

Hopefully, the KADE team's experience dealing with fabrication companies for miniConsole+ will help them if/when they choose (or design) a replacement AVR platform.

EDIT: Nitz has removed several images that he had previously overlooked.

dammit! I had a stock alert at c3k to warn me if their stocks got low, but it seems the website disappeared. Now I'm out of AVRs and need a keyboard encoder.

So, any sources out there at the moment?

Do I need to look for a different encoder?

Yeah they were down to 32 last I checked and was gonna order some but the shipping was killing it so was saving up to place a larger order (since the unit cost dropped and the shipping stayed the same) Then went back a couple weeks later and the site was gone !

Only place I've seen with stock is http://www.tynesidepcrepairs.co.uk/minimus-32-avr-usb - for 6.00 + 8.17 international shipping which is a bit high. (looks like the shipping there stays the same for multiples also so might not be too bad if ordering several )

Going back and reading this thread,  I posted this sentiment a few times.  Surprised an alternative hasn't been developed in that time.

Thanks Lilshawn, I will ask the vendor about this board.  Maybe he will test the KADE loader software with it (or even modify the KADE loader software to work with his board).

I'm addicted to cheap fast programmable keyboard encoders, and I need to find a replacement for the minimus !

would this work?? (mostly) it's not identical but...mostly?

http://www.ebay.com/itm/NooGroove-USB-Board-ATMEGA32U2-AT90USB162-AVR-Stick-/162099277204?hash=item25bddead94:m:mLP03sdfF9arxnlt9V8wmbg
It does use the atmega32u2, but there are several things that would lead me to choose a different board.
-- I'm not sure what bootloader it uses.
-- On the e-bay page, the "Operating Instructions" and "Preliminary Documentation" links are both broken.
-- I can't find anything about the NooGrove board on the NooElec webpage.

You might be better off going with this board from MattairTech. (Select "Atmel DFU" bootloader)

https://www.mattairtech.com/index.php/atmega32u2-usb-development-board-arduino-compatible.html

KADE Loader already supports the maxArcade prototype (same bootloader on a MattairTech AT90USB646/1286 board) so adding the 32u2 board shouldn't be too difficult.  :dunno

Worst case scenario is that you download the KADE source code, run "makefile" to generate the desired firmware(s), and upload the hex file to the board using FLIP. (FLIP tutorial here)

The pinout is shifted a bit from the Minimus layout, but it looks like the same pins are available on both boards.

EDIT: The Atmel DFU bootloader option requires a pullup resistor on pin D7. (HWB)  It could interfere with "shifted functions".

Thanks PL1.

I did some looking around yesterday, there are a lot of boards out there and I don't understand the pros and cons.  ATmega32u2 might be a bit old hat? ( I don't want to get caught by a discontinued board again next year). Also $15 plus tax and shipping and our new GBP exchange rates is too much for a bare board. I've been used to paying 5 for the minimus, so 15 is a bit steep.   

Lots of china clones of arduino boards based on ATmega32u4, and  $6 inc shipping from china is a good price point.  http://www.ebay.co.uk/itm/162015552758?

A windows HID is one of the easiest things to implement I tihnk. eg  https://learn.sparkfun.com/tutorials/pro-micro--fio-v3-hookup-guide

But I don't think I have the time to learn all this stuff from scratch, at least not before I need some encoders, so I might just pay someone to sort this out for me, either modify the KADE LOADER code or do something from scratch.

I only need two of the KADE options. USB HID keyboard and USB HID keyboard/mouse that takes trackball/spinner input. And I don't need any shifted functions or flipping between different key maps. And I don't need a configuration gui.  Just two pieces of code that will program the board, and that I can edit to choose the key codes if wanted.

Any offers?

Calling PL1 !

I've managed to compile some of the KADE hex files (it's a bit hit and miss which ones work straight from the repository). And they don't seem to work if you comment in the atmega32u2.  I'm guessing from the comment about 16k works on both that LOADER uses that one for both boards.

# NOTE - Stuff compiled for 16k will work on both!!
#MCU = at90usb162       # Minimus AVR 16K
MCU = atmega32u2       # Minimus AVR 32k 


Oddly it does produce a hex file if I change the chip to atmega32u4 which is my target anyway.


Some of the firmwares use LUFA code, and after copying in some LUFA files for different boards (leonardo and micro) I've managed to produces hex files for a leonardo atmega32u4.


So is this progress? I don't know.  I'm kind of hoping that all I need to do is understand how pins are designated and adjust that part of the code to match the new board, and then just load the hex to the boards when they arrive ???



In the KADE repository there are some old versions of the firmwares, kade-pin is a simple 20 buttons encoder without the later frills that i don't need.  So I'll work on that one.

For the trackball, the code for the trackball to USB mouse/keyboard is missing. So I may have to use trackball to USB gamepad. Is that  nothing to worry about? (for MAME on PC).

Great news!    :notworthy:

You're way deeper in the weeds on this than I've ever been.

Hope you're taking good notes so others can duplicate your success.    :applaud:

Sounds like progress to me.   ;D

As long as the 32u4 input pins defined in the firmware are connected to solder-holes on the board, it's just a matter of loading the firmware and hooking the right wire to the right solder-hole. (and maybe adding a pull-up resistor, depending on the board/bootloader)

I'll be glad to help you figure out the pinout(s) and document things so people can use alternate boards.   :cheers:

Once we have confirmed good writeups for specific board/firmware combinations, I'll add links to the OP.

For the trackball, the code for the trackball to USB mouse/keyboard is missing. So I may have to use trackball to USB gamepad. Is that  nothing to worry about? (for MAME on PC).
I never tested any of the KADE trackball/spinner firmwares, but the main thing that I'd be concerned about is that there were a few reports of backspin -- AFAIK the problem was never fixed.

Depending on the resolution of your trackball and how fast you spin it, this might be a problem.   :dunno

2 packages each with 2 boards landed on my doormat today. Visually you can tell they are from 2 different factories. They are chinese clones of this board   https://www.sparkfun.com/products/12640

I decided the easiest approach was just pile in and use FLIP to load the hex I built and see what happens. But FLIP doesn't connect to the micro board. Not having used FLIP before I got out a new Minimus board and used flip successfully to load a hex to it.

I'm guessing I need one of these pullup resistors on the RST or HWD pins like was done on the mattair board. About to have a read and then give something a go.


The micropro boards show up as COM3, whereas the minimus shows up as a USB device.

change of tack:  I had been thinking that Arduino IDE route might be better than trying to use the KADE stuff. So instead of working out how to use the board with FLIP, I opened the Arduino IDE and followed the sparkfun examples I pointed out earlier.

Very easy to use the IDE and program the board,  I've got a basic HID keyboard encoder working and will test it on Defender as soon as I can get it soldered up. I will need to think about debounce and using the internal pull up resistors on the inputs (sounds like the proper way to do it to avoid floating values). I wish I knew more about how MAME/Windows handles input, I expect that should influence the encoder design.

I might have to revisit the KADE firmware for trackball later, but at the moment I've got 8 Minimus which will cover me for trackball panels for a while. 

This might be premature! but you may not hear from me for a while, I've hopefully solved my encoder shortage, so now I've got to get back to building cabinets.

edit: as this is no longer on-topic I'll just leave you with this:

Quote

#include <Keyboard.h>

void setup()
{
  pinMode(9, INPUT_PULLUP);  // Set the button as an input

  Keyboard.begin();
}

void loop()
{
 
  value9 = !digitalRead(9);   // closed gives true

  // do some debounce routine and flip the state if valid input
   if (flipped) {
        if (pinstate9)  { Keyboard.press(key9);}
        if (!pinstate9)  { Keyboard.release(key9);}
        }

}

I got a similar "Pro Micro" knockoff and successfully loaded a few Arduino "sketches" on it, but haven't figured out how to load KADESTICK firmwares on it yet.

IIRC, Jon managed to do this, but I have no idea what software/procedures he used.  :dunno

FLIP works with the DFU and Atmel DFU bootloaders, but not with the Arduino bootloader.

I'm guessing I need one of these pullup resistors on the RST or HWD pins like was done on the mattair board.
The Mattair board only needs a pullup resistor because of the "Atmel DFU" bootloader -- the same Mattair board with a different bootloader does not require a pullup resistor.

There are three bootloaders available. Please select below.
CDC:   Recommended! Arduino and AVRDUDE compatible
DFU:   FLIP compatible
Atmel DFU:   FLIP compatible (External pullup on E2/B pin required!)

I'm feeling a lot more comfortable in the Arduino environment than when I was looking through the low level KADE code.

just wanted to chime in to this thread and say that the TX still makes minimus AVRs. They only sell to academia and hacker spaces these days tho. I'm personal friends with many of the TX guys including the founder and have a large batch of them here. If there is enough demand for them from the arcade scene, i can forward off your comments to them.

I just got into the arcade scene myself and bought a bartop kit from ebay. Haven't wired up player 2 yet but so far I'm having a blast.  :applaud:

Welcome aboard, MacRod.   ;D

If you can help arrange a way for arcade hobbyists to buy Minimus AVRs at a reasonable price, I'm sure that many members would be interested.   :cheers:

cheers. I'll forward the message off to them  if i get more feedback..I do have some questions tho.

From what i understand the Kade softare is still available and is open source but the add-on boards are no longer available, correct? Does any group or person make an aftermarket version of the board? What is a reasonable price that you would consider for the minimus these days? I know they originally went for $30USD and gradually went down before they pulled them.
