Ultra Low Power deepsleep #15

hallard · 2018-03-01T12:33:50Z

Added Ultra Low Power mode (30uA sleep mode)
Wake by LoRa module, avoid watchdog wake every 8s
Added new method to read battery voltage, needed if VCC<2.5V
Updated documentation
Bug fix with button wake
Press button more than 2s to enable 1minute window to upload new sketch when in deepsleep

- Added Hardware Reset of lora module at startup - Fixed push button duration bug - Set IRQ var to be volatile

Moved #include definition here Added wakeStatus to wakeCallback to get what waked us Added pointer to TheThingsNetwork object to enable Lora module sleep/wake up

removed #include definition (in .h now) Added wakeStatus bit field to wakeCallback to get what waked us Added pointer to TheThingsNetwork object to enable Lora module sleep/wake up Added IRQ for INT2 (Lora Serial Module) Added new configInterval method Optimized Light Sensor Changed deepSleep to support wake by lora module

Nice, thanks very much! Mostly code style issues.

Also looping in @laurensslats for testing

 ```

 - `bool enabled`: Enable or disable the interval callback. Enabled automatically by `onInterval()`, but you can use this method to temporarily disable it. Defaults to `false`.
+- `TheThingsNetwork * pttn`: This enable the interval callback but in this mode, the interval is passed to RN2483 or RN2903 module (this is why we need to pass pointer to object) with the command `sys sleep ms` and then it's the LoRa module that wake up the node. This is the most advanced Low Power Mode. In this mode, the watchdog is disabled and consuption again reduced.

Remove empty line

hallard · 2018-03-02T15:35:27Z

@johanstokking you want me to remove any use of printf, sprintf and snprintf, correct?

hallard · 2018-03-04T15:19:59Z

Requested changes are done

johanstokking · 2018-03-04T15:43:26Z

@hallard we try to keep dynamic memory allocations to a minimum, at least that's a goal!

hallard · 2018-03-04T16:40:12Z

removing printf is not a bad idea, I think it also save same pgm space (as soon as it's not used anywhere else in any lib)
