Hi
I am using ESP32 , i am using version v4.0 of idf. I cant say abt freertos version.
But i have encountered on issue, i dont understand the problem is at my end or libraries.
I am trying to create Timers for my routine, i see that after 10 timer are created i get error for next. i have approx 100k heap remaining, i dont think memory is issue
is there a limit for max timers we can use ? is it modifiable ?
kindly help me in right direction
When in doubt (although it’s probably documented somewhere) it’s at the beginning of each FreeRTOS source / header file comment.
Find the FreeRTOS sources and lookup one of the files.
I guess you mean FreeRTOS timers and the error on create is that it returns NULL, right ?
That’s strange because the number of timers is not limited except by available (heap) memory requested by pvPortMalloc in xTimerCreate …
If you have 100K heap left then there is no obvious reason why creating a timer would fail so I suggest stepping into the xTimerCreate() function in the debugger to see what goes wrong.
