What is UARTBus?

UARTBus is a library, toolbox and infrastructure that enables you to create decentralized multi master microcontroller networks whith devices has UART peripheral. Essentally it bounds the device's RX and TX UART peripheral and forms a bus connector.

This project is aim to fill the gap between other electrical bus systems:

• Form a bus, not just point to point (Not like UART, SPI, but like Ethernet, 1-Wire, CAN)
• Capability for multi master nodes (Not like 1-Wire, SPI, I2C, but like Ethernet, CAN)
• Use least wire as possible for communication (Not like I2C or SPI, but like Ethernet, 1-Wire or CAN)
• Fast as possible (Not like 1-wire but others) and maybe with configurable speed.
• Avoid complex external peripheral, use only basic components. (Not like Ethernet or CAN but others)
• Be cheap as possible.

And some not electrical goals:

• Be the communication protocol acceptable both low (microcontrollers) a high (PC applications) level softwares.
• Provide elevated functions like discovering and uploading code to the nodes.
• Integrate with popular softwares and libraries like arduino.
