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? - Mark |

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. |

Can the ATtiny2313-20PU be programmed with an EPROM Burner? If so, I can take care of it myself. - Mark |

I have plans on my site. Also, the free Bascom AVR programming software can be downloaded from MCS Electronics. |
