f28069 ADC channels

Other Parts Discussed in Thread: BOOSTXL-DRV8301, LAUNCHXL-F28069M

Dear team,

I am using f28069 launchpad with boostxl-drv8301 driver for my bldc motor.

successfully done potentiometer implementation with the board. But i want to add one more sensors for that i required ADC channel.

Attached pics shows my connections of my driver which is similar to the DRV board.

Can you please suggest whether i can add one more ADC read pin in this header?

Also please suggest if i made any wrong pin connection ?

Thanks.

I don't understand your question. If you are using LAUNCHXL-F28069M and only using 1 set of headers for the inverter there are at least 6 other ADC channels available on the other set.

there are plenty of ADC channels on this device (up to 16 on 100-pin package)

I apologise if i couldnt make you understand. The thing is that in the highlighted part of header, I showed the number of pins used with some GPIOs also (as showed in first pic).
My question is that can i attach 1 more ADC pin in the same highlighted header? e.g. can one of the rest GPIOs be configure to be used as ADC?

I know there are 16 ADC channels, but i don't want to use ADC channels of lower section header.
Hope it would be bit clearer.

Thanks.

Rahul,
You need to see if the pin from the F28069M connected to the header you want to use supports an ADC channel.
