The Lishui Parameter Configuator
Several Display types are supported basically. For most displays only speed and power are displayed and the support level, push assist and light on/off function are sent to the controller. Further settings in the display are ignored.
Displays, that are using the Kingmeter J-LCD protocol
Displays, that are using the Kingmeter KM5S protocol, the KM5S protocol uses an encrypted handshake on some OEM versions, so in some cases the lookup table has to be adapted to the certain display.
Displays, that are using the Bafang protocol
Displays, that are using the Kunteng protocol. Here some more settings can be done in the display, they are stored in the controllers emulated EEPROM.
This setting supports the EBiCS-Flutter app on android, see the EBiCS repo. The EBiCS Flutter protocol uses the ANT+LEV syntax. The autodetect routine can be started from the app.
In debug mode the controller sends UART data on the display connector. Use lines, that are not described here don't have to be adjusted
