Note Current State
This is at a really early stage, I stated on the implementation of the serial protocol.
NsPanel Custom Widget UI
This is a replacement for the stock ui on nspanel, it can be controlled via custom serial command, like the stock one (but with different commands). This enables a user experiance, where it's possible to use nspanel with custom UI, but without messing around with Nextion Editor, because it's possible to configure widgets.
Custom Protocol
55 BB [payload length] [payload] [crc] [crc]
Payload length contains the number of bytes of the payload.
CRC is "CRC-16 (MODBUS) Big Endian" calculated over the payload
This protocol does not try to implement broken JSON Commands with a specified type (lol). Instead the commands are plain text commands with parameters.
Example for valid Message
This message has to be generated for the Message "1337" (1337 is not a valid command, this is just an example)
55 BB 04 31 33 33 37 AB F1
