Hello Tom,
Thanks for your answer.
Yes i have noticed that. If that is the only way to use these devices, then they are not sufficent to measure a high speed because the speed drops from 3mbit to 20kbit. That is to slow for our backemf readings.
We have send the universal start-code to put all the device active with one command. After that i have send a restart with a read command for the first device followed by an new restart with the read command for the second device After that the bus drops down to normal i2c. The things that i like to know :
What is best way to speed up the i2c to the high speed mode.
Is sending a restart the best option for another devices read.
Had anybody some code sample for speeding up i2c
Greetings,
