The post to which you responded appears to be a duplicate of one to which I responded, in some depth, earlier today. As far as I can tell from the datasheet, 1.23 V is the output bias voltage, not the reference voltage for his ADC. I don't know from where he got his factor of (5000/1024), but it appears to be in error.
Iam giving 3Volts as the supply for the gyro.
Should i use ((Vout-Voffset)*5/1024)/sensitivity or ((Vout-Voffset)*3/1024)/sensitivity
Right now iam using the 1st equation.On stationary the gyro outputs around:x-axis -7.28deg/s and z axis -7.28deg/s
when i rotate quite fast along x axis the gyro outputs xaxis:-58.239deg/s zaxis: -7.28deg/s
and gives some positive values if rotated in another direction.
Is these values seems to be correct??
PLS help me out..!
