S32K344 EMIOS-TRGMUX-BCTU multiple channel conversion.

Alfredo_Rubio — Fri, 02 Aug 2024 11:42:21 GMT

We need to trigger the conversion of multiple channels synchronized with an eMios signal.

We are able to perform a single channel conversion based on this requirement, but fail to trigger multiple channel at once.

There is not example on a similar configuration in the MBDT. Could you give us some advice on this topic.

Thank you for the inquiry, indeed in the latest MBDT V1.5.0 from NXP Model-Based Design Toolbox for S32K3xx version 1.5.0.

You can check in the Motor Control models, for example s32k344_mc_pmsm_2sh_s32ct contains the EMIOS-TRGMUX-BCTU multiple channel conversion.

For more details on this you can check the document MCSPTE1AK344_- 6-step sensorless.pdf

This explains in more detail how the eMios-BCTU-ADC-TRGMUX-LCU peripherals are connected:

And how the BCTU creates a list of parallel conversions for the ADC.
