Hello everyone. We are currently trying to implemnt an image processing algorithm into TI's C6211 DSK. I've seen many pages about audio IO, but I haven't seen anything about other IOs. We're looking for ways to send data from HOST computer to DSP, process them in DSP, and send data back to HOST after everything is finished. An image size is something like 320x240(24bit). Is it possible to send and recieve data via parallel port that is connected to DSK? Or do we need to buy a PCI interface? Is it possible to send/recieve data from JTAG? Has anyone done this sort of thing? If there is a link which can help me out... Please please please help!!! Thanks, Atsuto |

Thus, you should be able to send and receive your data via the lpt port on the PC. I don't know the C6211 DSK but this is how it works on the VC5402 DSK: { There is a parallel port interface chip (SMC or something) on the DSK hooking up the PC's lpt port to the DSP Host Port Interface. Furthermore, the output of the parallel port interface chip is also connected to a TI JTAG test bus controller (TBC) supporting the JTAG debugging path. While debugging an application, the DSK specific Code Composer Studio driver sends debugging information via the PCs parallel port to the SMC and to the TBC to access the CPUs JTAG port. In Code Composer Studio, you can upload and download data to the DSP memory (via JTAG) but this would be an offline transfer. On the other hand, you could use DSP/BIOS and Real Time Data Exchange to transfer the data in realtime (tricky). } The easiest way should be transmitting data over the printer port to the C6x HPI (assuming you have the appropriate PC driver software for this). On the other hand, you could also develop your own parallel interface on top of the daughter card header on the DSK. Please check the DSK documentation and the software - most of the DSK hardware and software docu is somewhere"hidden" in the DSK specific CCS install paths.

Atsuto You can transfer images through the parallel port on the DSK but it is very slow as with the JTAG port. We are transferring images directly from a camera on the data bus via a FIFO but we do not send them to a host computer. I would expect you would need PCI to talk to a host in real time.
