Is it possible to use External LED ( via I2C (Link ) ) or Buzzer with Erle-Brain 3 ? It is really difficult to see the status leds on Erle-Brain3 over the frame
The I2C is a digital bus, you need a chip that talks I2C and afterwards turns on/off your LED.
I understood , Could it be possible to use PWM pins for the buzzer option?
I ordered an external I2C LED and tried with Erle-Brain 3 via second I2C port and It did not work. Is there a config for I2C ports? [ PS: External Compass which contains in GPS modules works . Also I ordered a pixhawk , I will try this I2C module with pixhawk to see modules works well] .
