Hi, I have some question about Interface DSK6711 to PC. As I know there are only two ways to interface DSK6711 to PC, One is LPT1 using EPP mode and the other is JTAG which could use XDS510 or XDS560. I have problem that I want to send image frame(640x480) from DSK6711 to PC. Currently, I am using the HPI via LPT1 to send one image frame to PC. But the speed is very slow (500 Kbytes/one image frame = 5-6 minutes). I have tried to solve the solution, I found that this problem could be solve by using XDS560 via RTDX which speed is 2-3 MBytes hence could send image frame for real time maybe about 15 fps. But this XDS560 is too expensive, I tried to find a low cost solution, cause my goal is not image acqusition, the image frame that I send to PC is only for debugging. Here is my question Is there any possibility to send one image frame to PC more than 500 Kbytes by using EDMA. Cause I saw in the TI datasheet, the HPI could use EDMA to transfer data. I mean that Is there any possibility to improved the HPI speed by using EDMA. I have another problem related to the DSK6711 interface. I couldnt found Serial Communication (SCI) in DSK62xx/67xx family. Is it true that DSK62xx/67xx SCI Port is not in use anymore ? Thank you Henrry Andrian |
