analog() (SystemSleepConfiguration)
SystemSleepConfiguration::analog, analog, SystemSleepConfiguration.analog
// PROTOTYPE
SystemSleepConfiguration& analog(pin_t pin, uint16_t voltage, AnalogInterruptMode trig)
// EXAMPLE
SystemSleepConfiguration config;
config.mode(SystemSleepMode::STOP)
.analog(A2, 1500, AnalogInterruptMode::BELOW);
Wake on an analog voltage compared to a reference value specified in millivolts. Can only be used on analog pins. Voltage is a maximum of 3.3V (3300 mV).
The AnalogInterruptMode is one of:
- AnalogInterruptMode::ABOVE - Voltage rises above the threshold
voltage. - AnalogInterruptMode::BELOW - Voltage falls below the threshold
voltage. - AnalogInterruptMode::CROSS - Voltage crosses the threshold
volagein either direction.
| Analog Wake Support | Gen 2 | Gen 3 |
|---|---|---|
| Wake from STOP sleep | ✓ | ✓ |
| Wake from ULTRA_LOW_POWER sleep | ✓ | |
| Wake from HIBERNATE sleep |
P2 and Photon 2 Devices:
Wake on analog is not supported on the P2, Photon 2, or Tracker M.
