Hi, I have installed ADSP-21160(M) Ezkit (having Parallel interface) from SpectrumSignal on VDSP++3.0. But the talk-through program when I am compiling is giving error, as the talk-through was written for VDSP-4. 1. version. VDSP++3.0 has a talk-through program for 21160 Ezkit (for USB interface) whereas my kit is having Parallel interface only. So, I want to re-write the talk-through program for my kit so that it runs smoothly on VDSP++3.0. Please help me in this regard, if anybody has written the talk-through program for the same. regards Juliba |

Hello, I have used both of these kits quite extensively. Here you have my comments, from my experience. The PP (Parallel Port) kit has a Xilinx CPLD, XC95144XL which performs several tasks (source code is in Verilog): - Act as a controller for writting to the onboard flash memory. - Act as a controller for read/write to the DSP. In this mode, it acts as the debugging interface, coupled with the monitor running in flash memory. The USB kit uses a Cypress USB controller as the deugging interface directly connected to the JTAG pins of the DSP, much like a real emulator (not just a debugging interface), so it is much more "transparent" and lets you use all of the DSP resources without limitations. So, the examples and programs originally developed for the PP kit use libraries wich perform the configuration and access to SPORTs, for example, so you don't have to do the "dirty stuff" for configuring the CODEC (AD1881A in both kits). Please read carefully your PP kit to know all of the limitations and implications of usage of a monitor program running from flash memory to access the DSP via Parallel Port (I think that on-chip timers are also used by the monitor). As the AD1881A is connected to the same SPORT in both kits (SPORT0, I think), you could use the talkthrough example from the USB kit on the PP kit. I say "could" instead of "can", because you should first check whether the example for USB kit interfers with DSP resources needed by the monitor program used by PP kit. Anyway, of course, you *can* generate a loader file from the TT (TalkThru) example for the USB kit, and burn the flash memory on your PP kit with this loader file. Beware that if you do this, you'll erase the monitor program from your PP kit's flash memory, so if you want to perform debugging tasks again, via Parrallel Port, you'd better keep a copy of the flash memory image, for later restore. I think the loader file with the monitor program is included in the installation. All of this within VDSP++ 3.0 (or even the newer 3.5) I hope I helped. If I can help even further, please reply back.
