ESP32_C3: TFT_eSPI init() is crashing
Posted: Mon Jan 01, 2024 8:42 pm
On my custom ESP32_C3 Super Mini board I am trying to connect a TFT display ST7789 with SPI interface.
As soon I am calling tft.init() the ESP32_C3 seem to crash and starting again. The following is the output shown in the TERMINAL from Platformio-development environment:
I spent hours to search I-Net for getting a solution - w/o result.
I am also using standard ESP32 (WEMOS D1 Mini) with the same display ST7789 - here tft.init() and all the functionality I am using from the TFT_eSPI library is working as expected.
Has anyone an idea what the problem is - I am lost and have no clue anymore what I could do to fix this problem.
Thanks much for all ideas how to identify the root for this issue.
Best, Bernd
As soon I am calling tft.init() the ESP32_C3 seem to crash and starting again. The following is the output shown in the TERMINAL from Platformio-development environment:
I simplified the code down to just a few lines where the problem clearly shows tft.init() is crashing. For reference I am adding the code here:* Executing task in folder ESP32C3 Super Mini: C:\Users\Bernd\.platformio\penv\Scripts\platformio.exe device monitor
