Try:

Code: Select all

esp_restart();

In a C block.


See https://docs.espressif.com/projects/esp ... m_api.html

Seems to work okay...

A simple program - just waits 5s then restarts and does it all again...

Glad to hear it works okay.

Gave me an idea to do an utility component for esp32 with some of these type 'commands' in it.

I did a small trial:

Restart() - restart the MCU
RegisterShutdownHandler(addr of macro) - macro to be called before restart (see demo)
UnRegisterShudownHandler(addr of macro) - unregister a shutdownhandler
GetRestartReason() - 1 is power on, 3 is Restart() called (there are others though I didn't look them up)
GetFreeHeapSize() - get some memory stats
GetMinimumHeapSize()
GetFreeInternalHeapSize()

Need to add the fcpx file to component directory (Global Options->Locations->Search For Components in)

Demo - is very simple and just displays the values from each routine. - then uses a ShutDownHandler to do a 5s countdown to a restart...

Any ideas on 'useful' macros (I just used a handful from the link above)
