Hi,
Please correct me if I'm wrong.
Consider an application that will read 6 bytes of data from I2C at 200Hz (each 5mSec) and will stop after 2000 reads. This will be...
Hi,
Apologies if this is an obvious question, but I haven't been able to establish from previous questions or the data sheet whether it is necessary to use an external...
