PBUS – an RS485-like multi-drop bus with half duplex serial protocol

overview There are three PIC source versions: PB12 is for 12-bit slave devices without interrupt PBUS is for slave devices with an interrupt, software UART implementation PB628 is for slave devices with an intterupt and a free hardware UART PBUS assigns a unique device ID in the range 1-f for every controller on the bus.
