I'm now using saadc in nRF52832 and wanna to use both ppi and manual

[jasonbu]

using **nrf_drv_saadc.**c and nrf_saadc.c nRF52832 with sd132v2.0

for example. i init a app_timer to update a adc channel per 10ms. and manually update the batt volt per second.

and the trouble is when init the adc channel nrf_drv_saadc_buffer_convert is called app_timer timeout and nrf_drv_saadc_sample called, everything all right.

and if I init the second channel, ppi will auto sample both channel, I guese it will cause power touble.

if when I init channel sample and uninit the channel nrf_drv_saadc_sample_convert by this funtion.

it always busy. even if I call nrf_drv_saadc_abort.

any suggestion?

Have you measured the difference in current consumption with 1 and 2 channels? It does necessarily consume a lot more.

Can you explain what you mean with this sentence? "if when I init channel sample and uninit the channel nrf_drv_saadc_sample_convert by this funtion." Did you first uninit the channel, and then try to sample it with nrf_drv_saadc_sample_convert ?
