How to configure ADC in continuous Read mode for voltage monitoring..?
I did the following method for configuration
#define ADC1_CHANNEL_NO 6
static int8_t AdcConfiguration()
{
adcStepConfig_t adcConfig;
uint32_t configStatus;
uint32_t baseAddress = CSL_MCU_ADC1_BASE;
BoardDiag_initADC(baseAddress);
ADCEnableIntr(baseAddress,(ADC_IRQENABLE_SET_END_OF_SEQUENCE_MASK|
ADC_IRQENABLE_SET_FIFO0_THR_MASK |
ADC_IRQENABLE_SET_FIFO0_OVERRUN_MASK |
ADC_IRQENABLE_SET_FIFO0_UNDERFLOW_MASK |
ADC_IRQENABLE_SET_OUT_OF_RANGE_MASK));
/* Initialize ADC configuration params */
adcConfig.mode = ADC_OPERATION_MODE_CONTINUOUS;
adcConfig.openDelay = 0x1U;
adcConfig.sampleDelay = 0x1U;
adcConfig.rangeCheckEnable = 0U;
adcConfig.averaging = ADC_STEPCONFIG_AVERAGING_16_SAMPLESAV;
adcConfig.fifoNum = ADC_FIFO_NUM_0;
configStatus = ADCSetStepParams(baseAddress, ADC1_CHANNEL_NO, &adcConfig);
if (configStatus != 0)
{
return -1;
}
ADCStepIdTagEnable(baseAddress, TRUE);
configStatus = ADCSetCPUFIFOThresholdLevel(baseAddress,
ADC_FIFO_NUM_0, 40U);
if (configStatus != 0)
{
return -1;
}
return 0;
}
static void BoardDiag_initADC(uint32_t baseAddress)
{
uint8_t delay;
/* Clear All interrupt status */
ADCClearIntrStatus(baseAddress, ADC_INTR_STATUS_ALL);
/* Power up AFE */
ADCPowerUp(baseAddress, TRUE);
/* Wait for 4us at least */
for(delay = 0; delay<4; delay++);
/* Do the internal calibration */
ADCInit(baseAddress, FALSE, 0U, 0U);
}
