Compiler/UCD3138064EVM-166: UCD3138064EVM-166

Moumita,

With 2.5V input, the ADC conversion result is close to 0xFFF (full scale).

With GUI, you can open memory debug and read the device registers.

Rds,Sean

This is not working.

When Vin is changed, is ADC result changed?
Where do you get the source code? The EVM code should work. You may reinstall the source code.

I am sending my program to you, please tell me whether if it looks ok. Though it is not giving me satisfactory result.


if(AdcRegs.ADCSTAT.bit.ADC_INT==1)//If the conversion is not complete
{
Ic= AdcRegs.ADCRESULT[5].all;
AdcRegs.ADCCTRL.bit.SW_START = 1; //RESTART
}

void rectify_vac(void)
{
Dpwm2Regs.DPWMCTRL1.bit.GPIO_A_EN = 1;
Dpwm3Regs.DPWMCTRL1.bit.GPIO_A_EN = 1;
t1=(Ic/2.5)*0xfff;
t2 = (1/2.5)*0xfff;
if(t1>=t2)
{
Dpwm3Regs.DPWMCTRL1.bit.GPIO_A_EN = 0; //now turn on neutral PWM
Dpwm2Regs.DPWMCTRL1.bit.GPIO_A_VAL = 1; //and then drive line always high
}
else
{

Dpwm2Regs.DPWMCTRL1.bit.GPIO_A_EN =0;
Dpwm3Regs.DPWMCTRL1.bit.GPIO_A_VAL = 1; //line drive low
}
}
