Programmer not found #2

Open VectorFever opened 2 years ago

VectorFever commented 2 years ago

Hi! I made this programmer with Arduino Nano. I have checked all connections, everything is ok. Anyways "EEPROM Programmer not found" error pops up from ui application and finddevice.py too. While in Arduino IDE memory dump works fine(A lot of garbage when there is no ic in socket and all zeros when it is). But when I'm trying to run memory fill command Arduino just freezes and doesn't respond until I reset it. There is Python 3.9 with pyserial-3.5 and tkinter on my PC, Windows 10. I will be glad if You help!

Did you use a CH330N or CH340N as a USB to serial converter? If you connected the Nano via its USB port, it probably wasn't recognized due to an incorrect identifier (VID/PID). But then you can change it in the Python script.
