Trigger ADC from both BCTU and other HW source S32K344

[oskarjohansson]

Hi, I want to trigger one ADC, both from BCTU and from other hw trigger source.

The BCTU is triggered from a eMIOS channel to enable center-aligned ADC reading in a PWM pulse and having the data into a FIFO.

I also need to trigger a group on the same ADC which I want to be triggered from a hw source, such as a PIT.

But when I initialize the BCTU with Adc_EnableCtuControlMode( ADC ) I cannot longer trigger the ADC, as I can read in the RTD ADC user manual 3.6.3 BCTU control mode.

Is there any other way to be able to use both the BCTU and a HW trigger source simultaneously?

Best regards,

Hi,

Thank you so much for your interest in our products and for using our community.

If you are in BCTU control mode, only the BCTU can start a conversion. All other trigger sources are ignored, including HW trigger sources.

Hope it helps you. 

Have a nice day!
