Configuring CC2650 Launchpad ADC with CCS Cloud

Other Parts Discussed in Thread: CC2650

I am trying to configure the ADC on the CC2650 Launchpad.

I was looking at the ADCBuf and ADC Projects available in the resource explorer to understand the API.

ADCBuf: dev.ti.com/.../

ADC: dev.ti.com/.../

However, I could not find where they designate a pin to be routed to the ADC.

A pin has to be internally routed to the ADC, right? How else would the ADC know where to sample from?

Where in these projects I can find the code responsible for the routing? Or am I misunderstanding how the ADC works?

    Someone in the TI-RTOS forum could give the best answer. However with the US holiday it could be Monday before they can reply.

    In looking at the code for the ADCBuf example I would look at the code in CC2650_LAUNCHXL.c starting at line 531 (ADCBUf begin) and line 589 (ADC begin). There are also a few relevant lines in Board.h at line 56.
