Recently, for my IMU (Inertial Measurement Unit) project, I had the necessity to add low-pass filter, in order to reduce the noise on the accelerometer sensor signal. For this purpose, I decided to use a 1st order IIR (Infinite Impulse Response) filter, because it is easy to implement and run on a microcontroller. In general, … Continue reading "How to calculate a first order IIR filter in 5 minutes"
This morning, before going to work, I finally had some time to assemble the first Fuelino Proto3 board. Since this board is only for testing purpose, in order to save some time I did not mount filter capacitors, I mounted a cheap electrolytic capacitor that I had quickly available, and put some cheap 12V Zener … Continue reading "Fuelino Proto3 first assembly"
