PMClass Class

Description
A class used for PowerMode control.

Syntax
class PMClass

Members

PMClass::begin

Description
Initializes the PowerMode settings for device, include type of the mode, wake up sources and related source settings.

Syntax
void begin(uint32_t sleep_mode, int wakeup_source, uint32_t wakeup_setting = 0);

Parameters
sleep_mode: Power Mode selection. Deepsleep mode: DEEPSLEEP_MODE; Standby mode: STANDBY_MODE
wakeup_source: Wake up source selection. AON timer, AON GPIO, RTC, PON GPIO, UART/Serial1, and Gtimer0 set by 0 to 5.
wakeup_setting: Settings for different wakeup sources and default is 0.
For AON time, it is a pointer to an array that stores clock(1:4MHz; 0:100kHz) and duration(by seconds).
For AON GPIO, it is pin number 21 or 22.
For RTC, it is a pointer to an array that stores time duration as day, hour, min and sec(0, 0:0:0, to 365, 23:59:59).
For PON GPIO, it is pin number 0 to 11.
For Gtimer0, it is time duration in seconds. (start from 1s)

Returns
NA

Example Code
Example: DeepSleepMode, StandbyMode

Notes and Warnings
“PowerMode.h” must be included to use the class function.

PMClass::start

Description

year: Start time by year. Starts from 1900.
month: Start time by month. 0 to 11.
day: Start time by day. 1 to 365.
hour: Start time by hour. 0 to 23.
min: Start time by min. 0 to 59.
sec: Start time by sec. 0 to 59.

Returns
NA

Example Code
Example: DeepSleepMode, StandbyMode

Notes and Warnings
“PowerMode.h” must be included to use the class function.
