BL 1800 Jackrabbit & USB

Hi,

I'm the application engineer at ZWorld. I don't know of any one who has done a USB host interface for Rabbit, or more importantly the required protocol stack to handle the host end of it. The sl811hs from Cypress looks like a good candidate in terms of USB host adapter, since it has a 8bit parallel bus interface which will be easy to interface to the Rabbit's AUXIO bus.

The sl811 devkit/appnote from Cypress also has some drivers in C which implement some simple host functionality, which shouldn't be too hard to port to Dynamic C. However, I don't think they have a mass storage driver that you would need in order to talk to a Flash disk.

See ya, -ingo

Well, actually I have to communicate with a digital camera with a USB interface, so I'm not sure if the technology is the same as a Flash drive.

It's not the same. The resources needed are much higher to deal with a camera. You would need several megabytes of RAM to handle the frame buffers. Some of the camera output jpeg frames, so you need to decode jpeg as well. I suggested that you look into a standard x86 SBC, rather than the JackRabbit's limited resources (Flash & SRAM in K's, not M's).

A few days ago, there was another poster asking for microcontrollers with USB webcam. You might want to check/share information with him, as long as you are not in the same school/classs/professor with him.
