Transfer data (8 bits) to a TFT LCD

m_giraldi — Mon, 22 Jul 2019 22:33:16 GMT

I have an application for TFT128x160, in this application I have the CS / RES / DI / WR / RD and D0 ~ D7 ports.
I am using MK22FX512Axxx12, I need to write 8 bits on ports D0 ~ D7, what is the best way to declare and write on D0 ~ D7 (8 bits)

Hi Marcel,

To write to D0 to D7 please make sure you:

Enable the clock using: CLOCK_EnableClock(kCLOCK_PortD);
Set the pin as GPIO using: PORT_SetPinMux(PORTD, pinNum, kPORT_MuxAsGpio);
Initialize the pins as output with:

gpio_pin_config_t config = {

kGPIO_DigitalOutput,

};

GPIO_PinInit(GPIOD, pin, &config);

To write data your approach using PDOR is correct.

Best regards,

Felipe
