Hi all, I have been using HPI to communicate between my PC application and my c6711DSK. As you know, there are problems with the API functions, and I have some reliability problems as a result. Because of this, I was thinking of using rtdx in addition to hpi, using rtdx to send commands and hpi to transfer data. The first question. Can I use rtdx without CCS? If yes, then how do I go about loading a *.out file to my DSP via rtdx as you would when using hpi. Are there api functions for this? Thanks for your help, Barry.

Barry To quickly answer your questions. No you cannot use RTDX without CCS, unless TI has changed this recently... At one point, I designed a fairly reliable and extensible HPI interface for the DSK. It used two locations in the C6711 parameter RAM for read/write flags and external memory (that the C6711 processor needed to CACHE clean) for transmit/receive buffers. I directly used the TI HPI drivers for the host side. Unfortunately, the host PC needed to poll the communications flags because there is no PC-side interrupt in the TI drivers. Unfortunately, I cannot give you the source due to company restrictions. We did successfully mate this interface (both PC host and DSP) to provide many demos and transfer MBytes of data.
