I am working on adding in ArduCopter support for ArduStation.

One big problem I am having is parsing the CSV string.  From the documentation on the internet sscanf() allows me to parse a string, however, it only seems to work when I try to parse a CSV containing values which are integer and it doesn't work when parsing values that are float

This is the line of code

sscanf(buffer, "%f,%f,%f,%f,%f,%f,%f,%f,%f,%f,%f", &gyro_roll, &gyro_pitch,&gyro_yaw,&accel_roll,&accel_pitch,&accel_z,&roll_err,&pitch_err, &roll_angle, &pitch_angle, &yaw_angle);

buffer is the line of CSV received from the "Q" command on ArduCopter.

all variables are of type float

If I replace the %f with %d and make all values and variables integer it works fine.

I'm quite new to programming Arduino, and I know very little C and C++, most of my coding is done in Obj-C
