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)

*** Attached (PDF) is the full summary

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,

        0,

    };

    GPIO_PinInit(GPIOD, pin, &config);

 To write data your approach using PDOR is correct.

 

Best regards,

Felipe
