Change Analog Pin number of SAADC in nrf52

[Ankush]

Hi,

I am working on one application in which I want to change pin number assign to channel 7 of SAADC in nrf 52. I am using Rigado BMD 300 module in my application. As per datasheet channel 7 is assign to P0.31. But I want to assign channel 7 to P0.6. This is because in my application I have designed a PCB in which only P0.6 pin is available. so I want this pin to be configured as channel 7 of SAADC.

Is this possible? and if yes How?

Can anyone help me in this regards?

You cannot use P0.06 (pin 8 in the QFN48 package) as an analog input. There are only 8 analog input pins on the nRF52, and these are fixed, as you can see in the Pin assignments section of the spec.

Hi Einar,

Thanks for quick response. But in nrf52 BMD 300 Rigado module, any GPIO pin can be configured to some different function. Correct me If I am wrong. Then why we cant do this with analog pins. Is it because they are hardware pins?
