Remote LCD Nokia5510/JLX12864 with ESP32

[kagouraki]

Hello once again.

I ordered the same TTGO display 4mb you suggested. I compiled micropython with the ugfx module and uploaded the files from the hat directory with make upload.

now the esp keeps restarting and nothing happens.

here is my serial output:

Code:

wifi timeout, reconnecting wifi 0.0

the backtrace decodes to this :

i understand there is something wrong with the ugfx module. 

do you have some thoughts Sean?

Thank you,
