* - Boot sequence: LEDs flashing (Red, then yellow, finally green)
|
|
*
|
|
* - etimer/clock : Every LOOP_INTERVAL clock ticks (LOOP_PERIOD secs) the LED
|
|
* defined as LEDS_PERIODIC will turn on
|
|
* - rtimer : Exactly LEDS_OFF_HYSTERISIS rtimer ticks later,
|
|
* LEDS_PERIODIC will turn back off
|
|
* - ADC sensors : On-chip VDD / 3, temperature, and Phidget sensor
|
|
* values are printed over UART periodically.
|
|
* - UART : Every LOOP_INTERVAL the Remote will print something over
|
|
* the UART. Receiving an entire line of text over UART (ending
|
|
* in \\r) will cause LEDS_SERIAL_IN to toggle
|
|
* - Radio comms : BTN_USER sends a rime broadcast. Reception of a rime
|
|
* packet will toggle LEDs defined as LEDS_RF_RX
|
|
* - Button : Keeping the button pressed will print a counter that
|
|
* increments every BUTTON_PRESS_EVENT_INTERVAL ticks
