Hi everyone
I have a platform that has a I2C device connected directly to a processor's
I2C pins.
Now I'm researching the way to send and receive information to this device.
The first idea we had was to use the I2C Protocol Stack, but I'd like to
clarify one point.
After reading the documentation related to the I2C Protocol Stack, seems
this is application just in case the system has a I2C bus were other
devices are connected.
As far as I could understand on out case, since the device is attached
directly to the CPU pins, I understand that the correct wai ti access this
device is using the CPU I/O Protocol.
Is my understanding correct?
In case someone has some details about a scenario like this it would be
really helpful.
Thanks and Regards
