SHUTDOWN USING DIETPI - ONBOARD UART

Post by Pr2 » Thu Mar 29, 2018 10:04 am

Hello everyone

Im trying to connect G27 emulating G29. My setup is RPI3 + arduino pro micro, using onboard uart. Also, i have downladed DIETPI premade image.
My problem is that Dietpi shutdowns itself and i dont know why. It happens (i think) when RPI3 is connected with arduino, and oddly, happens even when arduino is not turned on. Anyone has faced same problem? Is there any other image to load on RPI3?

Thx!

Do you have a voltage shifter between the Arduino Tx pin and the RPi Rx pin?

Yes, i placed the two resistors in order to divide voltage

Yes it definetly corerct. Im thinking that maybe my firmware is not correctly loaded. I have loaded the EMUG29PS4/atmega32u4.hex, maybe is needed other firmware? Other odd thing is that when i plug in pro micro only the green led is on, if I reset the board then 2 red leds are switched on as well as the green one.

I have finally found the answer to shutdowns. My wiring was incorrect. I have a new problem but I will open a new thread to explain that
