Compiler/TM4C123GH6PM: TM4C123 ADC APIs

Tool/software: TI C/C++ Compiler

Hi,

I spent to much time, a day, trying to figure out which statement causes FaultISR, even I used the latest library.

Without using Tiva-C API everything works fine. ADC APIs must have wrong in coding.

Break points didn't help me too. Even I used  ADC_CLOCK_SRC_PIOSC  instead of ADC_CLOCK_SRC_PLL  didn't help.

SysCtlClockSet(SYSCTL_SYSDIV_5 | SYSCTL_USE_PLL | SYSCTL_XTAL_16MHZ | SYSCTL_OSC_MAIN);

{// inside this block FaultISR occurs

SysCtlPeripheralEnable(SYSCTL_PERIPH_ADC0);

ADCSequenceDisable(ADC0_BASE,1);

ADCSequenceDisable(ADC0_BASE,3);

ADCClockConfigSet(ADC0_BASE, ADC_CLOCK_SRC_PLL | ADC_CLOCK_RATE_HALF,1);

ADCSequenceConfigure(ADC0_BASE, 3, ADC_TRIGGER_PROCESSOR, 0);

ADCSequenceStepConfigure(ADC0_BASE, 3, 0, ADC_CTL_TS|ADC_CTL_IE|ADC_CTL_END);

ADCSequenceEnable(ADC0_BASE, 3);

ADCIntClear(ADC0_BASE, 3);
}
