Part Number: MSP430FR5959

Hi All

I am looking for an ADC12 example for multiple ADC conversion on FR5959?

Specifically where it could capture many of the ADC channels all at once especially channel 0 1 2 3 and 0x0b (3v3 rail)

as per 34.2.8.2 Sequence-of-Channels Mode (Autoscan Mode) from user guide?

Thanks

It isn't difficult. Configure ADCMCTL0 and subsequent for the inputs you desire. The last ADCMCTL should have ADC12EOS set. ADC12MSC should be set in ADC12CTL0 and in ADC12CTL1 ADC12CONSEQx should be set appropriately. With subtle variations depending on if you want the ADC to automatically repeat the sequence or only perform it when triggered.

Hello Rodney,

We do not have a specific example for multiple ADC conversions. You can find the ADC examples available below and add what David mentions below.

I think the ADC12_A on the F5 series has much in common with the ADC12_B on the FR59 series. You can probably get a general idea from e.g. MSP430F55xx_adc_06.c here:
