Hi everybody. I'm looking for your help regarding Serial programming. Usually I have the classical chain for Pro Mini programming : computer - USB2.0 to TTL converter - Pins GND, VCC, TX, RX and DTR on the Pro Mini.
As I'd like to reprogram Pro Minis, I'm looking forward to creating a box with an SPI EEPROM containing the .hex file to be uploaded and a Pro Mini to emulate the computer - TTL converter part.
I'm quite sure that somebody else has already thought about it but I'm unable to find something on this forum (not sur I'm searching the right thing...).
Do anybody has an idea or a link with some information ? Thanks for your help.
