[chirp_users] bf-888s programming data protocol for arduino project

[Jim Unroe]

Hi Gary,

The BF-888s uses the "h777.py" driver module. It is available in the CHIRP
repository.

You may also be interested in looking at Baoclone. It is a basic command
line programmer that supports the BF-888s among other Baofeng models.
