Hi there,
I am trying to record the input value into an array for a time period, and this is my following code,
#include <ti/devices/msp432p4xx/driverlib/driverlib.h>
/* Standard Includes */
#include <stdint.h>
#include <stdbool.h>
int count = 0;
double array[100000];
int main(void)
{
/* Halting the Watchdog */
MAP_WDT_A_holdTimer();
//![Simple CS Config]
/* Configuring pins for peripheral/crystal usage and LED for output */
MAP_GPIO_setAsPeripheralModuleFunctionOutputPin(
GPIO_PORT_PJ,
GPIO_PIN3 | GPIO_PIN2,
GPIO_PRIMARY_MODULE_FUNCTION);
MAP_GPIO_setAsInputPinWithPullUpResistor(GPIO_PORT_P1, GPIO_PIN1);
MAP_GPIO_interruptEdgeSelect(GPIO_PORT_P1, GPIO_PIN1,
GPIO_HIGH_TO_LOW_TRANSITION);
/* Just in case the user wants to use the getACLK, getMCLK, etc. functions,
* let's set the clock frequency in the code.
*/
CS_setExternalClockSourceFrequency(32000, 48000000);
/* Starting HFXT in non-bypass mode without a timeout. Before we start
* we have to change VCORE to 1 to support the 48MHz frequency */
MAP_PCM_setCoreVoltageLevel(PCM_VCORE1);
MAP_FlashCtl_setWaitState(FLASH_BANK0, 1);
MAP_FlashCtl_setWaitState(FLASH_BANK1, 1);
CS_startHFXT(false);
/* Initializing MCLK to HFXT (effectively 48MHz) */
MAP_CS_initClockSignal(CS_MCLK, CS_HFXTCLK_SELECT, CS_CLOCK_DIVIDER_1);
//![Simple CS Config]
/* Configuring SysTick to trigger at 12000000 (MCLK is 48MHz so this will
* make it toggle every 0.025s) */
MAP_SysTick_enableModule();
MAP_SysTick_setPeriod(1200000);
MAP_Interrupt_enableSleepOnIsrExit();
MAP_SysTick_enableInterrupt();
/* Enabling MASTER interrupts */
MAP_Interrupt_enableMaster();
while (count<10000)
{
if (MAP_GPIO_getInputPinValue(GPIO_PORT_P1,
GPIO_PIN1)==GPIO_INPUT_PIN_HIGH)
{
array[count] = 1;
}
else
{
array[count] = 0;
}
}
}
void SysTick_Handler(void)
{
count++;
}
However when I tried to run the code I encountered the following error when debugging. I think it has somehting to do with MAP_GPIO_getInputPinValue(GPIO_PORT_P1,
GPIO_PIN1)==GPIO_INPUT_PIN_HIGH
