29 define KernelPackage/ucmb/description
30 The Microcontroller Message Bus is a tiny SPI-GPIO based communication
31 channel used to talk to microcontrollers over GPIO pins.
32 The lowlevel protocol is CRC16 protected, so one can be pretty sure
33 that the data transmitted and received through the /dev/ucmb node is not corrupted.
34 So no further checks should be needed at upper protocol layers.
35 The device node considers every read/write to be one packet. The maximum packet
36 size is either PAGE_SIZE (at least 4kb) or the microcontroller specific packet size
37 limit, which is likely to be a lot smaller than PAGE_SIZE.
38 To register an ucmb device, simply create a struct ucmb_platform_data
39 and register it via ucmb_device_register() from another kernel module.
40 Example implementations for the microcontroller-side code can be found in
41 the utils/ucmb/microcontroller_examples subdirectory of the OpenWRT packages feed.
