The idea: - make it very easy to create hardware gadgets by providing a firmware/hardware building block that talks 9p on the host interface side & interfaces with device specific hardware.
- use a "universal" 9p driver on the host side that allows access to any such 9p device even from a shell. - provide a standard way to find out device capabilities. - together they provide a plug-and-play setup. Example: connect an LED and a current sensor to this 9p device, other necessary hardware, add a few config bits and plug this device kn]]into a host. Now you should be able to turn on/off the light or sense its state. Similarly you should be able to control a stepper motor servo, cameras, microphones, other actuators, sensors, IO etc. Eventually you should be able to snap together enough of these components to build larger assemblies such as a 3D printer. Another example: a "hub" to multiplex such downstream devices and make them available to a host. This will probably have to ride on USB first. A verilog implementation would be useful in an FPGA! Would this be a useful component? If such a thing were available, what would you want to build with it? Do you think 9p is the right protocol for this? Ideally - connect anything to anything - authenticated connections - drive the device through a shell script - no new low level drivers - self-identifying devices with help and command syntax - signicantly eases the task of creating new h/w devices. ------------------------------------------ 9fans: 9fans Permalink: https://9fans.topicbox.com/groups/9fans/Ta4e584a373b05553-M35165d4278d95e41fd95b8f7 Delivery options: https://9fans.topicbox.com/groups/9fans/subscription
