My Gyro TL3GD20 is not working.
Hello,I am using the TL3GD20 gyro in the stm32F429 discovery board to develop my own driver. The output registers are fixed and they do not move, always at:I respect the 10 ms second before powering up.I activate the x y and z axis and set the PD reg...
Resolved! LIS2DE12TR accelerometer component query
Hello,We are going to use LIS2DE12TR accelerometer, in our ultra low power device, to wake on motion. Here is schematic for LIS2DE12TR, Our requirement :1) ultra low power consumption2) Wake MCU on Motion by INT_1 Pin Below are queries regarding sche...
Resolved! ILPS22QS Cleaning After Soldering
TN0018 calls out in the Process considerations section that the board must be properly cleaned after soldering if "self-cleaning" solder paste is not used. Are there any guidelines on cleaning methods that will not damage the sensor? Can the sensor p...
Resolved! DC bias from MEMS microphone using ADF on STM32U5
I have a MEMS microphone (IM72D128V01, using this eval kit) with PDM output connected to a STM32U5 NUCLEO board.It's connected to the ADF/Audo Digital Filter peripheral which I have configured to provide a 5th order CIC filter with a 32x decimation f...
Thermal response
One of the critical measurements for the analysis of bridges is the thermal response. The 201/109 combination has an average thermal response in the FFT of 1.5 milli-g - it is slightly frequency dependent, but ignoring that the standard deviation mea...
L3GD20 does not send the x y an z acceleration values
hello,I am using the L3GD20 to measure the angles, I have a 10 ms interrupt and in this interrupt service routine I read each time the 6 Output registers, I am configuring the gyro like this:GyroscopeDriver.TL3GD20_Reg_Struct.Who_Am_I = I_AM_L3GD20; ...
