Hi,
I am trying to calibrate a 9DOF Razor IMU by following this tutorial: https://dev.qu.tu-berlin.de/projects/sf-razor-9dof-ahrs/wiki/Tutorial
I have followed all instructions for uploading the firmware and I'm using the same IMU and FTDI basic breakout as decribed in the tutorial.
However, when I open the serial monitor I rarely see #YPR= ... , the rest is just noise. (I have checked the connectors and the baud rate)
What I want to do now is to check what is causing the noise by having the IMU send the signal to my pc via my Arduino Mega 2560 (instead of using the FTDI breakout).
My question is, can I simply connect the IMU to the Arduino like this:
9DOF Razor IMU Arduino Mega 2560
GND ------> GND
CTS ------> nothing
3.3V ------> 3.3V
RxI ------> Tx1 (Pin 18)
TxO ------> Rx1 (Pin 19)
DTR ------> nothing
I got a bit confused by this topic: http://arduino.cc/forum/index.php/topic,131968.0.html
It says you have to connect Rx to Rx and Tx to Tx but the tutorial says otherwise.
Another question: Can I use the Serial library to send the information from the IMU to my pc?
Something like this:
Serial.println(Serial1.read())
Any help would be greatly appreciated.
Thanks,
KdJ
