Does the SAADC have a SHORTS register?

[David Fernandez]

Hi there,

I am trying to automate the ADC sampling in a regular way.

Application timers seem to be a bit irregular if I depend on not loosing too many miliseconds on each 2ms interval, so I decided to use PPI events/tasks, as the SAADC seems to have driver functions to get the task register, and HAL functions to get the events register.

I was wondering if there is a SHORTS register for the ADC, so that I don't have to use PPI channels at all (couldn't find anything about it in the documnetation).

Seems a good optimization to me, given what was commented in the tech tour about it.

Hi,

 

No there is no SHORTS register in the SAADC module, I do not know the details but I would guess that it has to do with a limited number of envisioned use-cases. For your use case it sounds like continuous mode would be a good fit.

Hi Andreas,

How does continuous mode work? I did not find any documentation about it.

Hi,

 

It is described in the continuous sampling section under SAADC.
