Can you use an Arduino Uno as a prop plug substitute? The Arduino uses an ATmega16u2 for USB communications. By using, a jumper wire to hold the ATmega328 in reset (GND) you can bypass the ATmega328 and get serial communication from the ATmega16u2 on pins 0 and 1. In addition, the DTR line is available at c5 (100n). Looking at the prop plug schematics it looks like you would just need to add a transistor and resister to invert the DTR line and create an RC
So after making those changes (holding atmega328 in reset and jumper wire from DTR with transistor to invert DTR), would the Arduino Uno work like a prop plug for programming the propeller chip? Would the propeller IDE recognize the atmega16U2 for serial communication?
