I love it. But how i can use other IC USB to serial . Ex- CP21xx i no have ch330 chip.
@NotThing Hi, you have to make some changes in the board design ("USB to Serial Converter" box in the schematic) and in the Python script (eeprom.py the settings for pid and hid). However, I suggest to get some CH330N. They are dirt cheap, easy to use and need almost no support circuitry.
@wagiminator Thank you very much.But i can not find my USB to serial chip pid = ? hid = ?.How i can get it.
@NotThing hid='10c4' (actually it should be called vid), pid='ea60' but without guarantee because I cannot test it.
@wagiminator Thank you. I'll try again.
