Can you please tell me for what is the define traceTIMER_CREATE() ?
Is it empty now ?
Is it for the user implementation ?
Yes, for user definition. They allow you to add code into the kernel
without needing to edit the source files. Most commonly used for
tracing – the FreeRTOS+Trace tool generates all its data from trace
macros. This list is out of date:
In which filed should I write the implementation of those functions ?
For example – should I write the implementation of traceTIMERCOMMANDSEND() in timers.c ?
The page I just linked to describes where to define them.
