Hi,

I modified adc_ex2_soc_epwm example by initializing all peripherals in syscfg file. I noticed the following:

I have to add this line into main.c , if not, interrupt routine is not enabled. Why?

//
// Enable ADC interrupt, do not work if commented
//
Interrupt_register(INT_myADC0_1, &INT_myADC0_1_ISR);
Interrupt_enable(INT_myADC0_1);
/* even though in Board_init();
void INTERRUPT_init(){

// Interrupt Setings for INT_myADC0_1
Interrupt_register(INT_myADC0_1, &INT_myADC0_1_ISR);
Interrupt_enable(INT_myADC0_1);
}
*/

I need to use this statement, or again interrupt does not work

EPWM_setADCTriggerEventPrescale(EPWM1_BASE, EPWM_SOC_A, 1);

// is there a way to set it up from syscfg?

thanks vadim

Hi Vadim,

Let me take a look at this and get back to you as soon as possible.

Hi Vadim,

Did you add your own sysconfig file for this example and were you set up the project properties to handle the new sysconfig file configurations?

Here is a resource for how to add a syscfg file to a project.

Hi Ryan,

I added a new syscfg file. It looks like those two statements need to precede board file.

Device_init();
Interrupt_initModule();
Interrupt_initVectorTable();
Board_init();

thanks vadim

any comment regarding

EPWM_setADCTriggerEventPrescale(EPWM1_BASE, EPWM_SOC_A, 1);

// is there a way to set it up from syscfg?

Hi Ryan,

i found the way to set up prescaler form syscfg.

thanks vadim
