Tiny Reflow Controller V2 not working anymore after reprogramming

[PioAlgra]

Hi, I bought a Tiny Reflow Controller V2 and wanted to do a small change in the profile. I downloaded the code from github, installed all the necessary libraries (and the wch340 driver). I checked that V2 was specified and compiled and downloaded it in arduino (1.8.13, windows). Then I tried to restart the Controller and now the screen stays black, no keypress does anything and I don’t see anything on the serial port.

When I try to download code now (chosen MCU Board: Arduino Uno), I get STK500 timeout…

Could anyone please tell me what steps to do to get the TRC working again?

Thank you very much in advance.

Please select Arduino Pro Mini with ATmega328P 3.3V 8MHz as the board.

Hi,
thank you very much. I tried but unfortunately it is still not showing anything.
The code is from https://github.com/rocketscream/TinyReflowController/blob/master/TinyReflowController.ino and compiled and uploaded without problem.
However the display is not showing anything and there’s no activity on the serial port.
Is there any information I could provide you to help in finding the error?

I tried posting already, but the posts disapppeared…

Thank you
Pio

I think the issue is related to this. Please use v1.1.1 of the PID library.
