Respected Memebers, I have an application on TMS320C6711 IDK which is DSK 6711 with the daughter video card. I need to take the images from the video and by applying the optic flow algorithm, driving the vehicle. The idea is to have a driver less vehicle which will be driven by the algorithm for optic flow. I need to send the control singals (Start, Stop, direction) to vehicle. DSK is only having one parallel port for I/O. So, could anybody help me out with this? How to use parallel port as output port and if possible any example programs. As I am bit new to this field any help in this regards is appreciated. Thank you, Hiren Gajjar. __________________________________ |

How to transfer data using Parallel Port of DSK 6711?

Hiren- If I understand you correctly, you want the DSK C6711 board (with IDK video daughtercard) to run "stand-alone", using power from the vehicle and booting from Flash EEPROM, to provide output signals to control circuitry that drives the vehicle. In that case, I might suggest using either GPIO pins or interface to the daughtercard connectors using async interface and/or different memory space than the IDK daughtercard. If you are going to use the parallel port, then you pretty much need a PC parallel port on the other side; in that case you could read C6711 memory via the HPI every few msec to get updated control data. There is no way that I know of to go in "reverse direction" through the SMSC controller on the board. One major problem is that the HPI port is "target only" and does not have a way to initiate transfers. -Jeff > I have an application on TMS320C6711 IDK which is > DSK 6711 with the daughter video card.
