how to get adc data on coapp?

[Liverpool007]

what is code for ADC data on coapp(Single channel)?

[Jørgen Holmefjord]

I have made an example, but I have not tested it (I don't have a IoT setup to test on), but I checked that the example compiles and runs.

coap_adc.zip

You need to copy the ADC driver and HAL from SDK 11.0.0 into your nRF51 IoT SDK directory:

Copy the directory components\drivers_nrf\adc from SDK 11.0.0 to Nordic\nrf51\components\drivers_nrf in nRF51 IoT SDK v0.8.0.

Copy the files nrf_adc.c and nrf_adc.h from components\drivers_nrf\hal\ in SDK 11.0.0 into directory Nordic\nrf51\components\drivers_nrf\hal in nRF51 IoT SDK v0.8.0.

Best regards,

Hi, did you use your own example or the one I provided? I see that I set the ADC to use AIN0, which is also used for crystals. If you have not done this already, you should change the line:

static nrf_drv_adc_channel_t m_channel_config = NRF_DRV_ADC_DEFAULT_CHANNEL(NRF_ADC_CONFIG_INPUT_0);

to:

static nrf_drv_adc_channel_t m_channel_config = NRF_DRV_ADC_DEFAULT_CHANNEL(NRF_ADC_CONFIG_INPUT_2);

If you want to use P0.01 (AIN2).
