When I executed the initialization script via the following:
$ python3 init_parallel_mode.py
I got a message of
FileNotFoundError: [Errno 2] No such file or directory: '/dev/i2c-7'
There are i2c-1 and i2c-22 under /dev but no i2c-7.
I did connect them as instructed in the User’s Guide (Figure 6-1).
I guess the Raspberry Pi 4B didn't find the EVM.
Is there any way to check if the EVM is connected correctly to the Raspberry Pi 4B?
What could probably go wrong?
