Not working in ESP-IDF5.0

[ameharoo]

I just clone this repo, set pins in menuconfig and no see demo Display backlight changes correctly, but not displaying demo. Also: in esp-idf5.0 i had to fix types in ESP_LOG calls.

in esp-idf5.0 i had to fix types in ESP_LOG calls.

Thank you for reporting.

This is a big change from ESP-IDF V4.4. I have a lot of repositories, so I will gradually work on supporting ESP-IDF V5.

For the unsigned int32 logging format, an interim workaround is provided here. https://github.com/espressif/esp-idf/issues/9511

There are two types of ST7789 breakouts.
One has a CS pin and one does not have a CS pin.
I think there is an electrical problem around reset circuit in the breakout without the CS pin.
Perhaps the reset circuit requires a lot of current.
Ultimately I ended up using the following circuit.
And press the reset button several times.

Thanks for the answer! I tried this connection (through a transistor) and nothing happened. My circuit is using no-CS connection. It turns out that this screen is faulty? PS. I used 2N3904 instead SS8050

[nopnop2002]

Any NPN transistor will probably do. press the reset button several times.

It may work with one reset. Sometimes it works with over 10 resets.

I don't have the exact scope, so I don't know the real cause.

[mandolins99]

Changing devcfg.mode = 0; works for me.

[nopnop2002]

Changed SPI mode from 2 to 3. Test results are good. No pull-up resistor is required on the reset pin.
