Help For STM32 black_f407vg and RA8875 about gfx_tft HOT 2 OPEN

Hello, thank you for your interest!

The SPI version of the GFX_TFT class for RA8875, GFX_SPI_RA8875, has 3 constructors:

    GFX_SPI_RA8875(int16_t cs_pin, int16_t dc_pin, int16_t rst_pin = -1, int16_t bl_pin = -1);
    GFX_SPI_RA8875(int16_t cs_pin, int16_t dc_pin, int16_t mosi_pin, int16_t sclk_pin, int16_t rst_pin, int16_t bl_pin = -1);
    GFX_SPI_RA8875(SPIClass *spi, int16_t cs_pin, int16_t dc_pin, int16_t rst_pin = -1, int16_t bl_pin = -1);

The first one uses the default HW SPI channel as defined by the Arduino package for the board you compile for.
This is the only one I have tested with.

The second one should use SW SPI provided by the cloned Adafruit_SPITFT class.

The third should be able to use any SW or HW SPI class instance. It may bypass the Adafruit_SPITFT clone. Untested.

There is no other support for alternative HW SPI channels on multi-SPI capable processors.

Thanks @ZinggJM for your input , I am initializing the instance with GFX_SPI_RA8875 tft(PB12,PB1,PB15,PB13,PC5); but I cannot get it to work with this Black STM32F407 board using the TFT connector https://stm32-base.org/boards/STM32F407VGT6-STM32F4XX-M.html
