Original question:
MSP430FR5969: How to know which pins go to what ADC channels
Hi,
Looked at the datasheet and found the pins for A0-A3, A8-A9 and A14 and A15. Unfortunately these are already allocated to other functions. I need to connect four temp. sensor to my design, but can't figure out how to connect.
Thanks.
It doesn't look like they are available on this package. You'd have to upgrade to the MSP430FR6047 which is the same base silicon and modules, but higher pin count, more FRAM, but less LEARAM. Looking at table 7-2 in the datasheet, there are two ranges of ADC inputs which are not actually routed out of the package.
Alternatively, implement an Analog Switch to mux your temperature sensors into a single ADC channel if you have one available.
