I am working towards enabling USB connectivity to the PC via uIEC, and I've had some initial success. Of course, now I need to work on the protocol between the two endpoints. Although my initial thought was a low-level protocol (CMD bytes, data bytes), it turns out that for most disk access, it's more efficient to operate at a higher level. I've implemented a set of commands, but I'd like to solicit suggestions on something that might be standardizable, or at least has merit beyond my thinking. From a high level protocol perspective, the IEC routines can take care of handling the DEV/CHAN stuff and deliver to the firmware a complete command string (open "name" on channel X or open/exec "data" on channel 15), data requests (fill read buffer with data, write this data to storage) , or channel closure. Any thoughts on that? Any particular format folks might prefer?
