9dof sensor breakout
Posted: Fri Mar 15, 2013 1:30 am
Hello,
I recently bought a 9dof IMU and a 9dof sensor stick from Geeetech.
The IMU is working fine, but the sensor stick is not responding on the I2S interface:
running the AHRS software with the debug option returns me the "!ERR" message on the 3 sensors, which apparently, in the code corresponds to an empty or incomplete buffer.
Trying to read raw data from the sensors returns the following messages, unchanging with sensor moving or not:
#A-R=193.94,-256.00,665.60
#M-R=-40.62,10.52,163.62
#G-R=-57727.92,-965036.00,-176250.29
#A-R=193.94,-256.00,665.60
#M-R=-40.62,10.52,163.62
#G-R=-57727.92,-965036.00,-176250.29
#A-R=193.94,-256.00,665.60
#M-R=-40.62,10.52,163.62
#G-R=-57727.92,-965036.00,-176250.29
#A-R=193.94,-256.00,665.60
#M-R=-40.62,10.52,163.62
#G-R=-57727.92,-965036.00,-176250.29
The sensor is connected to the arduino uno board according to the scheme of the wiki. I tried several boards with the same results.
I also tried to connect through a logic level adapter board with the same results.
Do you have any suggestions ?
Thank you for your help
