Detailed Description

Driver for the BlinkM LED controller connected via I2C.

Connect the BlinkM to I2C3 and put the following line to the rc startup-script: blinkm start

To start the system monitor put in the next line after the blinkm start: blinkm systemmonitor

Description: After startup, the Application checked how many lipo cells are connected to the System. The recognized number off cells, will be blinked 5 times in purple color. 2 Cells = 2 blinks ... 6 Cells = 6 blinks Now the Application will show the actual selected Flightmode, GPS-Fix and Battery Warnings and Alerts.

System disarmed and safe: The BlinkM should light solid cyan.

System safety off but not armed: The BlinkM should light flashing orange

System armed: One message is made of 4 Blinks and a pause in the same length as the 4 blinks.

X-X-X-X-_-_-_-_-_-_-

(X = on, _=off)

The first 3 blinks indicates the status of the GPS-Signal (red): 0-4 satellites = X-X-X-X-X-_-_-_-_-_- 5 satellites = X-X-_-X-X-_-_-_-_-_- 6 satellites = X-_-_-X-X-_-_-_-_-_- >=7 satellites = _-_-_-X-X-_-_-_-_-_- If no GPS is found the first 3 blinks are white

The fourth Blink indicates the Flightmode: MANUAL : amber STABILIZED : yellow HOLD : blue AUTO : green

Battery Warning (low Battery Level): Continuously blinking in yellow X-X-X-X-X-X-X-X-X-X

Battery Alert (critical Battery Level) Continuously blinking in red X-X-X-X-X-X-X-X-X-X

General Error (no uOrb Data) Continuously blinking in white X-X-X-X-X-X-X-X-X-X
