Support for Rototron Rotary Joystick Interface?
(1/1)

Oops...
I blew something (probably the IC) in my Rototron Rotary Joystick Interface when I accidentally fed it 12V rather than 5V.
Is there anyway to get a replacement IC?

You probably fried the Atmel microcontroller chip (5.5V is their limit).
You could get another chip and program it yourself. I have the code on my site. You would need an Atmel ATtiny2313-20PI chip which I think is discontinued. However, the ATtiny2313-20PU replacement will also work. You can get a few free samples from the Atmel site.
Otherwise send me a message and I will arrange a repair for you.

Thank you for the information!
Can the ATtiny2313-20PU be programmed with an EPROM Burner?
If so, I can take care of it myself.

I doubt you could program it with an EPROM burner. However, you can build a simple AVR programmer for under $2 in just a few minutes. I have plans on my site. Also, the free Bascom AVR programming software can be downloaded from MCS Electronics.
