13 Testing your Blackmagic Shield and Library Installation
LED Indicators
Your Blackmagic 3G-SDI Arduino Shield has six indicator LEDs that confirm activity on your
shield such as power, UART, I
2
C and SPI communication, plus indicators to show when tally and
camera control overrides are enabled.
LED 1 - System Active
Illuminates when power is connected to the shield.
LED 2 - Control Overrides Enabled
Illuminates if you have enabled camera control in your Arduino sketch.
LED 3 - Tally Overrides Enabled
Illuminates if you have enabled tally in your Arduino sketch.
LED 5 - I
2
C Parser Busy
Illuminates when communication is detected between your shield and the Arduino
using the I
2
C protocol.
LED 6 - Serial Parser Busy
Illuminates when UART communication is detected.
When your Blackmagic shield is booting, the power indicator will remain off and LEDs 3, 4 and 5
will indicate the following activity.
LED 3 - Application image loading
LED 4 - EEPROM initializing
LED 5 - Memory check in progress
After a successful boot, the power LED will turn on and all LEDs will resume their standard
functions during operation.
In the rare case of a boot failure, all LEDs except for the failed activity will flash rapidly so you
can identify the cause of the failure.
