Reading values from a potentiometer using nRF52

[Tormod123]

Im quite new to development with the DK so bare with me.

Currently I am able to read digital values (0 and 1) from the potentiometer using pin P0.03.

I am using the function: nrf_gpio_pin_read(POTMETER_PIN)

How do I go about getting the analog values instead ( 0 - 1024 etc.)?

Hi,

Can you please tell me how to copy the configure file, include and code.

Thanks

This seems bit old thread.

namitha K M can you share some details like SDK version, hardware and what you are trying to do?

Hi,

Can you help me please, You make one example code that is SAADC with ble_app_uart combined code and send me please. I am waiting for your quick response.

Thanks.

It's not that difficult and since you are getting started, it is recommended to go through these examples at-least.

Let us know in-case you are getting some issue, we may try to help you.

Hi,

I have tried the combined code as saadc with ble_app_uart, from that i am getting some error as below

"error:  #20: identifier "NRFX_TIMER0_INST_IDX" is undefined"

Can you please tell me how to solve this error. I am waiting for your quick response.

Thanks

Hi,

You may take a look at the ble_app_proximity example. It uses the SAADC to sample the voltage on VDD.

Also, note that TIMER0 is reserved to the Softdevice (System on Chip resource requirements) so you need to select another instance and make sure it is enabled in sdk_config.h. E.g. TIMER1_ENABLED.

Best regards,
