Other Parts Discussed in Thread: CC430F6137

Hi , Does the CC430F6137 have the ADC10_A module ? Also is there a way to sample the channels in different rates ( on the ADC12_A or ADC10_A ) ?

It has one ADC12 only. So you will have to sample all the channels in the same rate.

Do you have references ? Since the datasheet didn't help me much , it was more general for the CC430 family.

Yes, you can see it in the datasheet page 4, take a look at the functional block diagram.

Indirectly, and only on the ADC12(A).

On the ADC12 you can program a sequence of channels to sample. In this sequence, a channel may appear multiple times. By proper distribution o fthe sampling requests, you can sample different channels at different speeds.

e.g.
1-2-1-3-1-2-1-4
This samples channel1 four and channel2 two times as often as channels 3 and 4.
