TMS320F28388D: Program/setup a ADC/SOC for F28388D

Wen Li

Part Number: TMS320F28388D

Hello;

Based on the F28388D's datasheet, there are 4 ADCs in it, and each ADC has 16 SOCs, so there are total 64 SOCs. Is this correct?

So if I want to setup the ADC-A's SOC3 to acquire the analog signal on pin ADCINA5(pint# T3 of 337-ball ZWT package). Is the following C statement correct?

ADC_setupSOC(ADCA_BASE, ADC_SOC_NUMBER3, ADC_TRIGGER_EPWM1_SOCA, ADC_CH_ADCIN5, 80U);

Also can I setup the ADC-A's SOC5 to acquire the analog signal on pin ADCINA5(pint# T3 of 337-ball ZWT package)? And the C statement is as following?

ADC_setupSOC(ADCA_BASE, ADC_SOC_NUMBER5, ADC_TRIGGER_EPWM1_SOCA, ADC_CH_ADCIN5, 80U);

Thanks

Hi Wen,

Each of the 16 SOCs can be set up independently and can be assigned to any ADC input channel. All or part of the SOCs can also be assigned to only one input channel, like what you have stated above in the C function ADC_setupSOC().

Best regards,

Joseph

Hi Joseph;

Thanks for your quick response!

Just want to confirm: so my both C statements are legal, correct?

ADC_setupSOC(ADCA_BASE, ADC_SOC_NUMBER3, ADC_TRIGGER_EPWM1_SOCA, ADC_CH_ADCIN5, 80U);

ADC_setupSOC(ADCA_BASE, ADC_SOC_NUMBER5, ADC_TRIGGER_EPWM1_SOCA, ADC_CH_ADCIN5, 80U);

Best regards

Wen
