EV2300 and SMBus bus speed

Carl Fosler

Is there a way to change the SMBus bus speed? As best as I can tell, out of the box, the EV2300 seems to communicate with slave devices at 33 Kbs, but I have two different hosts that we interface with, and they run at 10 Kbs and 50 Kbs, so I would like to change the speed so that I can duplicate the enviroment of the host that we will interface with.

No, we cannot change the bus speed on EV2300.

Since my original posting, I have discovered that the EV2300 will response at either 33 Kbs or 66 Kbs. Not clear how the EV2300 choices what speed it uses, but I'm guessing that it uses the response speed to the first TxRx message.

It would be nice to be able to force the EV2300 to run at the faster speed.

Hello,
is it possible to chance the speed in the SW?
