In case someone needs this…
Working with very fast data flows from an LPUART I was in need of a very performant handler for inter-task communication because I want to send data from my uart task to a ui task. I came up with this simple programm that can transmit data just like the xQueue fifo queue, but much faster:
Feel free to use and modify this code in case you need something like this. This saved me a lot of trouble that came up when I was using xQueue. Also, if you find any mistakes or have suggestions on how to improve the code… Let me know!

Also, I’ve summed up some different functionalities in my handler to make it (from my pov) easier to use from all different kinds of tasks.
