K60 ADC eternal sequencing of 12 inputs

[michelc]

Hi, I have to scan 12 single ended inputs of ADC1 with 8 bits result eternally.

I would like to do this without CPU intervention, so in DMA mode modulo 24, using 2 buffers of 12 bytes.

Is this possible? (cfr. X-Scale Stellaris can)

Thx,

Michel

An application note appeared yesterday that should answer your question.

Thanks Norm, that's just what I was looking for!
