When I used the blue pill with Arduino_STM32 and the MCUFRIEND_kbv library, the display worked fine on the 8-bit 8080 interface
//LCD pins |D7 |D6 |D5 |D4 |D3 |D2 |D1 |D0 | |RD |WR |RS |CS |RST| |SD_SS|SD_DI|SD_DO|SD_SCK| !!!WORKED!!!
//STM32 pin |PA7|PA6|PA5|PA4|PA3|PA2|PA1|PA0| |PB0|PB6|PB7|PB8|PB9| |PA15 |PB5 |PB4 |PB3 | **ALT-SPI1**
When I switched to the kernel Arduino_Core_STM32 and began to use the bodmer library, two of my displays do not display anything, except for a white display.
Display 1
Display 2
At the same time, the code compiles without errors, is loaded via STLink into a black pill and outputs information via UART, but images, incl. no data is sent to the pins.
I have suspicions about fake black pills and a compiler.
P.S. Arduino IDE 1.8.19
