LVGL *must* be compiled with LV_COLOR_DEPTH=16 (currently LV_COLOR_DEPTH=32 #252

Closed 8fb790dd closed 1 year ago

tried to build firmware for port RP2 with LV_COLOR_DEPTH=16 with repo lv_micropython, according documented command for ESP32:

make -j -C ports/rp2 LV_CFLAGS="-DLV_COLOR_DEPTH=16" BOARD=PICO USER_C_MODULES=../../lib/lv_bindings/bindings.cmake

But maybe Makefile Parameters or Makefile for RP2 should be changed? Do you have a hint for me, what i should change? thx a lot in advance

Get the RuntimeError below by from init of the generic python st77xx.py driver: " File "libs/gen_st77xx.py", line 479, in init File "libs/gen_st77xx.py", line 448, in init RuntimeError: LVGL must be compiled with LV_COLOR_DEPTH=16 (currently LV_COLOR_DEPTH=32. MicroPython v1.19.1-657-g89c3b3943-dirty on 2023-01-05; Raspberry Pi Pico with RP2040 "

Hi @8fb790dd ,

The Makefile/CMake build system of the rp2 port probably doesn't handle LV_CFLAGS correctly.
I'm not using rp2 so I'll wait for some rp2 user to fix this and send a PR.

For now, as a workaround, you can edit lib/lv_bindings/lv_conf.h and set LV_COLOR_DEPTH there to 16.

thx a lot for the workaround hint :-) as soon as i am a little bit more familiar with the lvgl lib and the lv_bindings machinery i will take a deeper look to the make/cmake ;-)
