Re: How to implement tcp_sent callback ?

FreeRTOS shouldn't care about that: a pointer is a pointer is a pointer. The heap debugging message does however hint at something writing exactly one byte past the end of the allocated memory region; perhaps you have an off-by-one error somewhere?

Re: Problems with sleep timer

I think your issue is that the sleep time you specify is larger than a 32-bit value. This is not an issue for esp_sleep_enable_timer_wakeup as it takes a 64-bit value as an argument, but you're not calculating a 64-bit argument as uS_TO_S_FACTOR is specified as a long which is only 32-bit. My conver...

Re: How to use SPIFFS

That's pretty much impossible to say from the coredump... can you show your code here?

Re: Cannot build WiFi AP example (<property> not defined)

Those lines normally get dropped in a sdkconfig.h that is generated after you configure the project for the first time. Simply build the project once and that file will exist and the issues should be solved.

Re: ESP32 and MAX7219 daisy chain problem

What exactly is 'after a while'? Is it reproducably the same time every time, or does it differ? I'm wondering if it could be a thermal issue... I also seem to remember that chips like the MAX7219 sometimes are faked, so where did you obtain them, from a reputable source like Digikey or from an Alie...

Re: interrupt timer not work with library

The IRAM_ATTR has very little to do with this. Your basic problem is that you cannot directly use an object method as a callback, as the information wrt *which* object the function is called on is lost. The solution for this would be to work around the issue by passing the object in the argument to ...
