View Full Version : I2C fast to slow at runtime

This project requires a 100k device and a 400k device on the same bus.
The I2C slow command appears to be compile only.
Is there a way to change fast to slow and back again at runtime?
Thanks.

No. But as far as I know all 400K devices work on 100K.

Yes, it works fine. At the moment we have a 900 us read (Honeywell pressure sensor), but at 400k it's about 225 us, and saving the extra time would be useful.

If you need the speed, then what devices are running at 100K?

or use the mssp module if your chip has one

Microchip TC74.
We used this for the TO-220 packaging - it is screwed to a motor where it is difficult to put a PCB.

Thanks, I'll look into that.
