I am building an IMU for a robot using the Teensie 4.x as the main compute engine.
During development I am using the 4.1 to be able to write all the raw sensor data to the SD card for algorithm development.
"Production" unit would use the 4.0 to save space.
I just took the IMU for a drive to work in my car to get some live data to play with.
I noticed that my car FM radio gets interference when the Teensie is running.
The interference is a series of clicks.
I am assuming this is the periodic writing of data to the the SD card or the periodic reading of the gyro/accel chips via SPI.
Has anyone else noticed this behavior?
