* Allow scaleValue() for 32bit values * Victron: Implement CAN message 0x360 This one-byte message is set to 0xff to request charging below a certain SoC threshold (10% in my tests). * Pytes: Add support for native CAN protocol The recently added PytesCanReceiver.cpp implements the Victron CAN protocol. This change additionally adds support for the native Pytes CAN protocol messages. Features only supported in Pytes protocol: - High-resolution state of charge / full and remaining mAh - Charge cycle counter - Balancing state Features only supported in Victron protocol: - FW version - Serial number Note that the only known way to select the native Pytes protocol is via the serial console (Cisco-compatible cables work): ``` login config setprt PYTES logout ``` to return to Victron protocol use: ``` login config setprt VICTRON logout ``` to return to DIP-switch based protocol setting: ``` login config setprt DIP logout ```
