How to Deal With Clock Stretching on the Raspberry Pi @Raspberry_Pi #PiDay #RaspberryPi
via RaspberryPiPod
I was getting I2C read errors when using the new TE AmbiMate MS4 sensor board (review coming soon!) with the Raspberry Pi 4. I contacted TE about it and they asked me to try a Pi 3. So I did, and it worked absolutely fine.
It was an intermittent issue on the Pi 4 (everyone’s favourite sort of error!), and so I did some research and found some information on something called ‘clock stretching‘.
