Gyro sensor
12.2.2014
Today the first delivery from Adafruit with the L3GD20 arrived.
I soldered the header strip to the breakout board and connected it with four wires with a I2C interface on the control board. There was a little problem, because Arduino has not yet uploaded the Eagle board files to their web site, and the I2C connectors are not labelled, so I had to to measure voltages and do some try-and-error.
If you have the robot in front of you, so that the I2C connectors are top left, then the I2C signals are:
| Pin | Signal |
|---|---|
| 1(Top) | SCL |
| 2 | SDA |
| 3 | VCC |
| 4(Bottom) | GND |
I downloaded the Adafruit library and installed it. I removed the #include "Wire.h" directive, because
that's already included in the RobotLibrary. And in the example sketch I changed
Adafruit_L3GD20 gyro();
to
Adafruit_L3GD20 gyro;
