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"
When using software SW1 (efi_davide_20160131_v1), it is possible to request information to the ECU in real time, using the serial communication provided by the Arduino Micro Serial1 port. SW1 supports 8 bytes ASCII format commands (from PC, service tool, or logger), and they are interpreted by the following function, which is called every time 8 … Continue reading "ECU Software V1 Service Commands"
