Micro: MKV10Z32VLF7
IDE: MCUXpresso
I am trying to configure two pins on this micro to be digital outputs: PTC6 (pin 39) & PTC7 (pin 40). Code as follows:
gpio_pin_config_t PortC6 = {kGPIO_DigitalOutput,1}; // LED0, startup as HI
gpio_pin_config_t PortC7 = {kGPIO_DigitalOutput,1}; // LED1, startup as HI
.
.
.
void BOARD_InitPins(void)
{
CLOCK_EnableClock(kCLOCK_PortC);
PORT_SetPinMux(PORTC, 6U, kPORT_MuxAsGpio);
PORT_SetPinMux(PORTC, 7U, kPORT_MuxAsGpio);
GPIO_PinInit(GPIOC,6U,&PortC6);
GPIO_PinInit(GPIOC,7U,&PortC7);
}
After running the above code, neither of the pins are high.
I read back the following registers:
GPIOC_PDIR: 0x0 - Incorrect, read only register, should be 0xC0
GPIOC_PDDR: 0xC0 - Correct (both pins assigned as outputs)
GPIOC_PDOR: 0xC0 - Correct (both pins assigned level '1')
A value of "0" in the "GPIOC_PDIR" register indicating:"0 Pin logic level is logic 0, or is not configured for use by digital function."
What this is telling me is that I cannot assign these two pins as digital logic. Surely this is not correct? What am I missing here?
