Hi Rob, I merged your two threads into one. Also, in the future, please use the SyntaxHighlighter when pasting code, I changed your posts to reflect that. Your code is having trouble reaching the ISR. Try to set a breakpoint in there to see if it ever reaches. I took the example code that we have and modified it to use the same 4 pins that you are trying to use and it seems to be working fine. /* DriverLib Includes */ #include "driverlib.h" /* Standard Includes */ #include #include static uint16_t resultsBuffer[4]; int main(void) { /* Halting WDT */ MAP_WDT_A_holdTimer(); MAP_Interrupt_enableSleepOnIsrExit(); /* Zero-filling buffer */ memset(resultsBuffer, 0x00, 4); /* Setting reference voltage to 2.5 and enabling reference */ MAP_REF_A_setReferenceVoltage(REF_A_VREF2_5V); MAP_REF_A_enableReferenceVoltage(); /* Initializing ADC (MCLK/1/1) */ MAP_ADC14_enableModule(); MAP_ADC14_initModule(ADC_CLOCKSOURCE_MCLK, ADC_PREDIVIDER_1, ADC_DIVIDER_1, 0); /* Configuring GPIOs for Analog In */ MAP_GPIO_setAsPeripheralModuleFunctionInputPin(GPIO_PORT_P5, GPIO_PIN2 | GPIO_PIN0, GPIO_TERTIARY_MODULE_FUNCTION); MAP_GPIO_setAsPeripheralModuleFunctionInputPin(GPIO_PORT_P4, GPIO_PIN3 | GPIO_PIN1, GPIO_TERTIARY_MODULE_FUNCTION); /* Configuring ADC Memory (ADC_MEM0 - ADC_MEM3 (A3,5,10,12) with no repeat) * with internal 2.5v reference */ MAP_ADC14_configureMultiSequenceMode(ADC_MEM0, ADC_MEM3, false); MAP_ADC14_configureConversionMemory(ADC_MEM0, ADC_VREFPOS_INTBUF_VREFNEG_VSS, ADC_INPUT_A3, false); MAP_ADC14_configureConversionMemory(ADC_MEM1, ADC_VREFPOS_INTBUF_VREFNEG_VSS, ADC_INPUT_A5, false); MAP_ADC14_configureConversionMemory(ADC_MEM2, ADC_VREFPOS_INTBUF_VREFNEG_VSS, ADC_INPUT_A10, false); MAP_ADC14_configureConversionMemory(ADC_MEM3, ADC_VREFPOS_INTBUF_VREFNEG_VSS, ADC_INPUT_A12, false); /* Enabling the interrupt when a conversion on channel 3 (end of sequence) * is complete and enabling conversions */ MAP_ADC14_enableInterrupt(ADC_INT3); /* Enabling Interrupts */ MAP_Interrupt_enableInterrupt(INT_ADC14); MAP_Interrupt_enableMaster(); /* Setting up the sample timer to automatically step through the sequence * convert. */ MAP_ADC14_enableSampleTimer(ADC_AUTOMATIC_ITERATION); /* Triggering the start of the sample */ MAP_ADC14_enableConversion(); MAP_ADC14_toggleConversionTrigger(); /* Going to sleep */ while (1) { MAP_PCM_gotoLPM0(); } } /* This interrupt is fired whenever a conversion is completed and placed in * ADC_MEM3. This signals the end of conversion and the results array is * grabbed and placed in resultsBuffer */ void ADC14_IRQHandler(void) { uint64_t status; status = MAP_ADC14_getEnabledInterruptStatus(); MAP_ADC14_clearInterruptFlag(status); if(status & ADC_INT3) { MAP_ADC14_getMultiSequenceResult(resultsBuffer); } } Regards, Akash Patel
