Technology

Project was written in the Python.

Working description

After entering the serial port name, you can manage the bargraph via json protocol.

Commands

• Set all red segments light on with power of light 70%

{"Content": {"Address": 255, "IsRequest": true, "Power":70, "Red": [1, 1, 1, 1, 1, 1, 1, 1, 1], "Green": [0, 0, 0, 0, 0, 0, 0, 0, 0]}, "Crc": "bf"}

• Set all green segments light on with power of light 70%
