Hi all,
I am new with the dsp's. I am trying to setup the adc of the Piccolo 28027. I want to convert the channels in simultaneous mode.
My first step has been trying to modify the example called lab3 but it doesn't work.
My code is the following:
void InitAdc(void)
{
asm("EALLOW"); //Enable EALLOW protected register access
AdcRegs.ADCCTL1.bit.RESET=1; //Reset the ADC module
//Must wait 2 ADCCLK periods for the reset to take effect.
//Note that ADCCLK=SYSCLKOUT for F2802x/F2803x devices.
//Power-up and configure the ADC
AdcRegs.ADCCTL1.all= 0x00E4;
DelayUs(1000); //Wait 1ms after power-up before using the ADC.

Can anybody tell what is wrong? Or correct?
Thank you
