MCUIO/LININOIO - Virtualizing MCU peripherals

MCUIO/LININOIO - Virtualizing MCU peripherals

The MCUIO/LININOIO subsystem allows a Microprocessor Unit (MPU), somehow connected to a Microcontroller Unit (MCU), to see the MCU's peripherals as standard Linux peripherals (i.e. gpios, i2c adapters, pwms, ...). The basic communication protocol is completely generic, it just defines ways to read/write a (virtualized) memory space on the MCU. Standard, vendor independent memory maps are then defined for each kind of MCU peripheral, so that MCU specific implementation details can be ignored by the MPU. Interrupt events can be spontaneously sent by the MCU to the MPU as write requests. The protocol is transport independent, only a bidirectional channel is required (for instance rs232 or even a network connection).
