My setup is as follows:
- STM32duino Official Core v2.0.0
- Arduino 1.8.13
- F411 BlackPill
- LVGL 8.0.2
- ILI9341 with touch on SPI1
I load the supplied LVGL_Arduino example and change LV_COLOR_DEPTH to 16 and specify my screen width and height. I modify the example so that the “Hello Arduino” message is displayed.
The example compiles and I upload it to the F4111, which runs and displays the label. However, when I activate the serial monitor, nothing is displayed when I touch the display.
The touch screen is working which I verified using the supplied Keypad_240x320 example from the TFT_sSPI library.
What am I missing?
