hi all.
moving project from old esp-idf3.*.* with old arduino-esp to latest one (esp-idf 5.1.2, latest arduino-esp).
project build on device TTGO-T-Display, with old arduino-esp all works well, but when i build project under latest one, then i got errors on boot and can't get screen to work:

3 times same error.... how to get them to work in latest arduino-esp? or what changed with pin-initialization?

with modifying esp32-hal-gpio.c:167 got pins with this error:5, 16, 23, 4 - all of them are for screen

found myself.

in old arduino-esp was able to write before set mode, now need set pin mode before any write.
now initializing looking this way:

Code: Select all

pinMode(TFT_CS, OUTPUT);
digitalWrite(TFT_CS, HIGH); // Chip select high (inactive)

going now to find why my screen still not work after migrating...
