direct write registor will be more faster about arduino-stm32-8bittft HOT 4 CLOSED

void STM32_TFT_8bit::write8(uint8_t bytes) {
    TFT_DATA->ODR = bytes;
}

Is this code valid for all STM32?

My code should work on STM32F0/F1/F2/F3/F4/F7/G0/G4/H5/H7/L0/L1/L4/L5/U5/WB/WL.

I search the CMSIS header files, every STM32 MCU both have GPIO ODR registor, so it works for all.
use this method, the lcd data pin have to connent to a GPIO port 0-7pin and rest of the GPIO pin 8-15 can't be used

Thank you for your research.

I understand

Your proposal is very attractive.

I will consider whether to accept your proposal over the weekend.

Changed from LL_GPIO_WriteOutputPort function to port output data (ODR) register.

You can toggle the behavior with this definition.
