Forum Post: CCS/TMS320F28379D: DAC A OUTPUT UPDATE

Part Number: TMS320F28379D Tool/software: Code Composer Studio Good day, I am using the ADC SOC EPWM example in which I added DAC configuration in order to test the ADC to DAC circuit. I could verify that that the circuit works well, but the DAC output seems not to update the output once I change the ADC input. I verified that the new ADC value is updated in the Registers window. However the Expressions window keep the initial value. How do I make sure that the DAC ouput follows the ADC input ? Please follow below the interrupt command and the windows result interrupt void adca1_isr(void) { v_fonte = AdcaResultRegs.ADCRESULT0; v_recomp = v_fonte + 10; DAC_PTR[DAC_NUM]->DACVALS.all = v_recomp; }
