Hi

I have been searching answer for this sceniorio in I2C communication.I Hope some one here will give me ansmwe for this.

I have a system with one master communicating with one slave@400Kbits/sec on I2C bus.
I want to add a new slave device which can communicate to master only at 100Kbits/sec.

i.e one master two slave(1-@400Kbits/sec and 2-@100Kbits/sec)


With this sceniorio how do I communicate with slave devices?DO I need to reconfigure the master I2C code to slow communicating device or I2C protocol itself will take care?


Please help me

Thanks & regards,
Praveen
 

Yes, you can adjust the speed based on which device you are communicating to. This can easily known because the I2C slaves have a unique Address.
Otherwise the slow receiver will be overflown with excess data or the full capacity of the fast receiver will not be utilized.
 

ok which controller u are using and is your controller having built in I2C protocol?
and which compiler using also.
