Using TRGMUX with RTDs on the S32K118

hns80 — Fri, 22 Apr 2022 00:01:21 GMT

I'm trying to use the lpit and the PDB to trigger ADC conversions every 10ms using the RTD low level drivers.

The TRGMUX is needed to route the lpit's trigger output to the PDB's trigger input and I see a driver for TRGMUX and configure it, but this only creates a data structure. I can't find the library call to initialize the TRGMUX with this data structure.

The RTD_MCL_UM mentions a TRGMUX IP driver on the last page. The detailed description is blank.

How can I use the interval timer to trigger ADC conversions using the RTDs? The library appears to be incomplete.

Hi,

I think just Trgmux_Ip_Init should be called, Trgmux_Ip.h need to be included.

Function is defined in Trgmux_Ip.c

Trgmux_Ip_StatusType Trgmux_Ip_Init(const Trgmux_Ip_InitType * const pxTrgmuxInit)
