@prenticedavid hello! Please help me. I've changed board from a stm32f103c8t6(bluepill) to stm32f401ccu6(blackpill). Connected blackpill as bluepill:

//LCD pins  |D7 |D6 |D5 |D4 |D3 |D2 |D1 |D0 | |RD |WR |RS |CS |RST| |SD_SS|SD_DI|SD_DO|SD_SCK|
//STM32 pin |PA7|PA6|PA5|PA4|PA3|PA2|PA1|PA0| |PB0|PB6|PB7|PB8|PB9| |PB12 |PB14  |PB15  |PB13   | **SPI2**

Load into blackpill code from LCD_ID_readreg.ino

Read Registers on MCUFRIEND UNO shield
controllers either read as single 16-bit
e.g. the ID is at readReg(0)
or as a sequence of 8-bit values
in special locations (first is dummy)

Anybode graphictests not work. Code of examples that compiles successfully on the blue tablet does not compile on the black tablet. Do you no longer support the library MCUFRIEND_kbv for new chips?
