Cheap Arduino Serial Terminal
https://www.electronics-lab.com/cheap-arduino-serial-terminal/
Peter Scargill writes, As it happens I’m experimenting on a 1284 chip which while being Arduino-compatible kind of, it does have another serial port, so without disconnecting my FTDI – I hooked up the second serial port to the home control serial and fired the DEBUG command at the latter. As you can see on […]
