Function Documentation

digitalWrite()

void digitalWrite	(	uint8_t	pin,
		uint8_t	val
	)

Allow digitalWrite to be used for pins on the IO expander.

This function overrides the default digitalWrite provided by the Arduino core so we can use it with pins on the IO expander IC. If the pin number > 0x80 then the bits > 0x80 are masked off and the request is sent to the IO expander library.

For example, passing in pin 0x82 will ask the IO expander library to write to its pin 2.

Parameters

pin	the GPIO to write to; values > 0x80 will be handled by the IO expander library after masking off the bits > 0x80. @val HIGH or LOW

loop()

select_rtc_slow_clk()

void select_rtc_slow_clk ( void  )

static

Switch the RTC clock source to the external crystal.

This code is copied from the ESP32 Ardiuno core, and slightly modified so it only tries to use the external crystal before falling back to the 150 kHz internal oscillator.

timeout_task()

void timeout_task

(

void *

pvParameters

)

A simple timeout task. Runs on core 0 so the app code does not interfere with it.

If 14 minutes passes and timeout_restart has not been set to false, power to the modem is shut off and the ESP32 is rebooted.

Parameters

pvParameters

not used.
