For DSK C5402 board, I remember that the TI DLL will work, but it is slow and sometimes you have to download more than once -- occasional memory accesses do not "stick". I'm sorry I cannot be more definitive. I have not used the TI DLLs in a long time. In our labs, we use DirectDSP for all DSK boards with a host interface. The main reasons are: a) higher transfer rate, b) do not need to pause or halt processor to transfer data, so time-sensitive things like monitoring debug data inside an interrupt routine are possible. -Jeff > Ajit S.H. > > > i have 2 questions to ask. > > 1) why do we need to run api' on visual c++? > > 2) what process r included in interfacing hpi that is > > in creating a channel(tms320c6711dsk)? > > Using that method, you can communicate at medium rate (up to 200 to > 300 > kbyte/sec) > with DSP.
