Hallo,
I have to collect data from multiple external i2c devices.
My question is, what is the correct way?
1: Open i2-device-file, set slave address, read data, close i2c device
file and go on with the next one
2: keep the i2c device file open all the time, and change slave address
before every access to device
3: ???
greets
Dirk
