ESP8266 Community Forum

The Arduino software has a number of symbols defined by GCC's PROVIDE keyword,
eg: PROVIDE ( ets_post = 0x40000e24 ) where the ets_post function is then
called with ets_post(LOOP_TASK_PRIORITY, 0, 0).

Can anyone confirm that these addresses are in the ESP8266 firmware, rather
than the Arduino shim, and does anyone know of any documentation covering
the ESP8266 firmware calls? (Apart from their names in the Arduino software.)

Thanks - Will

All provides are for ROM functions (build in the chip itself). Definitions for some of them you will find in the tools/sdk folder of the Arduino env for ESP8266

Many thanks - that makes things much easier.
