How to check SAADC is enabled?

[ndarkness]

Hello,

I would like to know how I can check whether the SAADC is enabled or nor on my application. I am disabling the SAADC with nrf_drv_saadc_uninit(); after configuring it, however when my interruption is triggered to sample it seems that the saadc is not started so I would like to check if that's right or not.

Thanks in advance,

Hi,

You can check if the SAADC peripheral is enabled by calling the HAL function nrf_saadc_enable_check(), but from your question I'm not sure this is what you want.

If you call nrf_drv_saadc_uninit(), the SAADC driver will be uninitialized, and the peripheral will be disabled. If you try to sample after this, without calling nrf_drv_saadc_init(), you will get an error code.

Best regards,

Jørgen

But with this function I will pass an saadc event type which will be filled if the saadc is enabled right?

No, nrf_saadc_event_check() will do that. nrf_saadc_enable_check() will return the value of the ENABLE register.

@Jorgen, if I do as told, I get an error too few arguments to function 'nrf_saadc_event_check' looking into nrf_saadc.h it expects an event as the proto states __STATIC_INLINE bool nrf_saadc_event_check(nrf_saadc_event_t saadc_event)

Why are you trying to use nrf_saadc_event_check?
