Use push button to go to sleep/wake up.
Use a queue to transmit messages between system and display task (sleep & wake up for now).

@ -28,6 +28,9 @@ I've tested this project on the actual PineTime hardware.
|

* One big font to display the time (hours : minutes)
|
||||
* BLE advertising, connection and bonding
|
||||
* BLE CTS client (retrieves the time from the connected device if it implements a CTS server)
|
||||
* Push button to go to disable screen (and go to low power mode) / enable screen (and wake-up). **NOTE** : I'm not completely sure the power consumption is optimal, especially in sleep mode. Any help to measure and debug this is welcome.
