Hi,
We are using ADXRS290 gyroscope. We have made three boards, out of which Board 1 is working fine and problems related to Board 2 and 3 are presented below. All the three boards are identical.
Board 2
1. We are able to R/W the register and power on the Gyro.
2. The data from both the axis are gibberish. The value ranges from -20 to +120 deg/sec in both the axis.
3. On further investigation, we found that Cp voltage is only 25V, we replaced the Cp, however, the voltage remains the same.
What further can be done to identify the issue?
Board 3
1. We are able to R/W the registr and power on the Gyro.
2. The data from y axis is okay, however, data from x axis is not correct. X axis is immune to sligh rotations and when higher rotations are provided, the maximum value registered is approximately 4 deg/sec.
3. Cp value for this board is 38V. FYI, we checked, Cp value for Board 1 is also 38V. (Operating voltage for Cp provided in datasheet is 31V)
What further can be done to identify the issue in x axis?
