I'm using STM32H7A3 16bit RGB+3wireSPI to a 5" LCD with ST7701. I plan to use STM32H7A3's LTDC function. Where do I find sample codes to display basic shapes on LCD? .h file for ST7701 registers is also helpful.
Thanks.

Basic pixel, line, rectangle primitives into the frame buffer:
STM32Cube_FW_H7_V1.8.0\Drivers\BSP\STM32H7B3I-EVAL\stm32h7b3i_eval_lcd.c
Other BSP examples/releases have text and circle drawing functionality too. Honestly not that complicated at a frame buffer level, probably find 40+ years of examples for raster type graphics from an MCU
Registers on ST7701 will be same across all brands of MCU, and platforms
Up vote any posts that you find helpful, it shows what's working..
