rero 1.0.1

Rero is an efficient communication protocol intended for transmissions of byte frames over e.g. a serial interface or buses. It builds upon COBS which allows for a minimum encoding overhead. It is perfectly suited for MCUs with DMA support.

Did somebody asked what is it good for? Here are some qualities of Rero:

A C implementation written for STM32 MCUs is available here. It builds upon a very efficient ring buffer implementation tailored for UART interfaces, which of course utilizes DMA support for transmission and reception.

Quick start

Rero requires Python 3.5 or newer to run.

$ pip install rero

Usage

import rero

reroPacker = rero.Packer(1) 	# own address = 1

# Dummy payload
payload = bytes([1, 2, 3, 4])

msgToSend = reroPacker.pack(payload, 20) # Packing with dedicated address = 20

# msgToSend may now be sent e.g. by use of pySerial...

# Unpack received frame
for payloadRcd in reroPacker.unpack(msgToSend):
	print(payloadRcd)

Further examples are given in the docs.
