ADC+DMA+SPI for FRDM-KV31F

Dears,

 

  We need 2 channels 1Mbps ADC conversion rate to output result via SPI, is there any example source code for this in FRDM-KV31F?

 

BRs,

Ray

Hello Ray,

The KV31 does have two ADCs which are capable of up to 1.2MSamples/second in 12bit mode. You mentioned 1Mbps, so it should be doable albeit it would also depend on the size of the samples.

There is not an SDK example with exactly this configuration, but there are some ADC and SPI examples on the FRDM-KV31F SDK which may help as a starting point.

My apologies for the inconvenience.

Regards,
Gustavo
