vedirect

WIP

Fork of https://github.com/rosenstand/go-vedirect

Go package for VE.Direct

go-vedirect can read data from the VE.Direct serial protocol used in compatible products by Victron Energy.

It currently uses the tarm/serial Go package for setting up the serial port.

Has been tested on a Raspberry Pi Zero W connected to a Victron Energy SmartSolar MPPT 75/15 solar charger.

Disclaimer

This is my first Go program. It's not pretty (yet). Suggestions for improvements will be highly appreciated.

Usage

s := vedirect.NewStream("/dev/ttyUSB0")
fmt.Println(s)
for {
	block, checksum := s.ReadBlock()
	if checksum == 0 {
		fmt.Println(block)
	} else {
		fmt.Println("Bad block, skipping:", block)
	}
}

TODO

• Proper error handling.
• Godoc support.
• Use a larger buffer instead of doing a read() for every byte.
• Improve interface and naming.
