Title: Raspberry Pi questions, very technical
Post by: Sarver Systems on February 06, 2015, 02:44:06 pm: A friend of mine at work is looking into getting one.
We were discussing what it is, how it works etc...

Then it dawned on me, and idea I have.

But, I know absolutely nothing about them, so here is where you come in.

Is there any that the Pi can be used as a board tester?

For example, connect the Pi, via the proper harness to an arcade board, and have it test all of the proper outputs (also via a harness) and display on the screen a list of proper readings along with actual readings.

Basically, I want to build a computer-controlled test system.

No. I guess you're thinking about JAMMA boards. I don't see how you can use a Pi to test anything on a PCB.

Exactly. You want to test boards, build one of these like I did: http://forum.arcadecontrols.com/index.php/topic,121731.msg1291487.html#msg1291487 (http://forum.arcadecontrols.com/index.php/topic,121731.msg1291487.html#msg1291487)

I'm building a supergun with built-in display as we speak.

I want to test pinball boards, as well as Pac-Man, etc... boards.

I want to test down to component level.

Here's the question to ask, then... How?

You can't! For example: You need a logic tester for testing integrated circuits. That means you have to take the IC out of it's socket and insert it into the tester. In my opinion the Pi is NOT an alternative for doing even that.

But holy ---steaming pile of meadow muffin--- is that complicated.

Through the JAMMA harness... NO! :lol
