Command Interface
The command interface of the BK8500 series uses a 26 Byte packet interface. A command is a single packet and each command either returns a command status response packet or a command specific packet.
Basic usage:import bk8500functionscreate a list of 26 bytes - cmd=[0]*26set the fields in the packet, the last of which is an 8-bit checksum - bk8500functions.csum(cmd) returns a checksum value.

Organization
Python
Within the Python folder there are examples of command sequences and a basic function library to simplify issuing commands.
bk8500functions.py
This is the 'library'. Extensions and improvements will likely happen here in the future. Today, this helps to create the 26-byte packet, calculate the checksum and print the returned values. Below is a typical example of using this set of functions. Normally the unit will be put into 'remote' mode before any other command is issued.
8500List.py uses bk8500functions.py and creates a list sequence in the load.
LabView
