How can use multi channel saadc on nrf52832?

[Judge]

Hi everyone,

I have a project that needs to use multiple saadc channels but I don't want to use ppi but use app_timer. So is there any way I can change between saadc channels?

Hi,

Sorry for the late reply. You need to call nrf_drv_saadc_sample(). Set multiple channels with nrf_drv_saadc_channel_init() and make sure you have a buffer size with N*enabled_channels with nrf_drv_saadc_buffer_convert().

For triggering the sampling with nrf_drv_saadc_sample() it's the same if you use PPI or app timer.
