When using ICSP to program Uno from Arduino Due, the Arduino Uno will not program because the TX light is stuck on. If I press the reset button the RX light flashes twice and then the TX light turns permanently on
The Due is a 3.3V board
The Uno is a 5V board
Can you see a possible problem ?
Maybe that the ICSP voltage pin is not outputting the correct voltage, but I dont see how that would affect the Uno transmitting.
My code does not invole the Uno transmitting almost at all
I cant connect any other pins because every single pin on my Uno is connected.
I could attempt to connect the Uno to a barrel plug and power it that way but still program via ICSP
If the Uno requires 5V to program it and it is only getting 3.3V there will be a problem
