/** @addtogroup led LED Control
|
|
* @brief This section covers functions related to the bi-color red/green LED mounted behind the LCD.
|
|
* @details The SAM L22 is an exceedingly power efficient chip, whereas the LED's are relatively power-
|
|
* hungry. The green LED, at full power, consumes more power than the whole chip in active mode,
|
|
* and the red LED consumes about twelve times as much power! The LED's should thus be used only
|
|
* sparingly in order to preserve battery life.
|
|
* @note Some watches use a red/blue LED instead of a red/green LED. You will be able to determine this
|
|
* easily when you double tap the reset button: if the pulsing bootloader LED is red, you have a
|
|
* red/green edition; if it is blue, you have a red/blue edition. For red/blue watches, build your
|
|
* project with the command `make LED=BLUE`, and the watch library will automatically swap the pins
|
|
* so that watch_set_led_red sets the red LED, and watch_set_led_green sets the blue one.
