I am using the SCTimer match mode to generate trigger for DMA on the board LPC54608. But it seems that there are problemes.
I use the PIO0_0 FUNC_4 as SCT0_GPI0, and the PIO0_2 FUNC_3 as SCT0_OUT0. And when I debug the project, the COUNT register doesn't change. And the SCT has never send the trigger to DMA.
static void GPIO_Init(void)
{
CLOCK_EnableClock(kCLOCK_Gpio0);
CLOCK_EnableClock(kCLOCK_Gpio1);
//Define a digital output pin configuration,
gpio_pin_config_t configOut =
{
kGPIO_DigitalOutput,
0,
};
GPIO_PinInit(GPIO, SCT0_OUT0_PORT, SCT0_OUT0_PIN, &configOut);
GPIO_WritePinOutput(GPIO, SCT0_OUT0_PORT, SCT0_OUT0_PIN, 0);
IOCON_PinMuxSet(IOCON, SCT0_GPI0_PORT, SCT0_GPI0_PIN, IOCON_INPFILT_OFF | IOCON_DIGITAL_EN);
IOCON_PinMuxSet(IOCON, SCT0_OUT0_PORT, SCT0_OUT0_PIN, IOCON_FUNC3 | IOCON_INPFILT_OFF | IOCON_DIGITAL_EN);
gpio_pin_config_t configIn =
{
kGPIO_DigitalInput,
0,
};
GPIO_PinInit(GPIO, SSEL_PORT, SSEL_PIN, &configIn);
GPIO_PinInit(GPIO, SCT0_GPI0_PORT, SCT0_GPI0_PIN, &configIn);
// GPIO_WritePinOutput(GPIO, SSEL_PORT, SSEL_PIN, 0);
}
