Adding analog input to Logs #21

Closed albertofast closed 5 years ago

albertofast commented 6 years ago

Dear all, I bought the Sparkfun Razor imu m0 to compare its results with an industrial optical motion tracking system ( double integration to extract trajectory plus euler angles). The IMU will be used on a model falling in the air from about 3m height and then impacting on the water. I would like to add to my logs an analog input: a voltage signal ranging from 0 to 5v, sampled @100Hz like the rest of the imu data. As I am totally new to arduino I kindly ask you a suggestion of how and where to modify the code to add the voltage read to the log file data output and to the serial monitor. Thank you!

Please refer to this Arduino Analog Input Reference Page. Also the logging section of the firmware can be found here: https://github.com/sparkfun/9DOF_Razor_IMU/blob/master/Firmware/_9DoF_Razor_M0_Firmware/_9DoF_Razor_M0_Firmware.ino#L168
