Hi Jorgen,

Thx for the tips. It was the trick I was waiting for.

I'm pretty sure I've already read about that on the DevZone (I think I need some vacation)..

Anyway, thx for the quick and great support.

Best regards,

Fabien

Hi,

The problem is that you have configured the SAADC with OVERSAMPLE set to 8X, which requires you to trigger the sample task 8 times before the END event is generated. You can fix this by enabling BURST mode for the channel, by adding this line to your saadc_init function:

channel_config.burst = true;

Burst will make the SAADC sample the channel X_OVERSAMPLE times from a single SAMPLE task.

Best regards,
Jørgen
