SAADC Scan Mode mixes channel buffers whan fast.

[schef]

Hi, i have a strange problem which happens when i use scan mode to get 3 separate channels on saadc.

For example when i use uint32_t ticks = nrf_drv_timer_us_to_ticks(&m_timer, 200); everytihing is ok but whan i use 50us buffers get mixed up?

Is this possible?

I use nrf52 with sdk 12.2.0

@schef:I don't understand why you need a timer here, I assume you only need one sample per channel ? The saadc example we used the timer just to show how this can be done automatically and periodically with the help of EasyDMA. I'm not sure you need that for your use case.
