Post by thread:Reading Parallel Ports

Howdy All, I am involved in a Zilog project that will not run properly on an ICE BOX. Therefore we must burn chips to debug it. We need to monitor our internal RAM values, and have interfaced to a PC via a serial port. However this slows the system down too much. By now you all are wondering, "where is the PIC part?" Well, here it is. I am presently writing some PIC code to provide a faster clocked serial link between the ZILOG part and the PIC. The PIC will then output this data to a PC in a parallel format. My problem is how to read the PC's parallel port fast enough. My forecasted data rate will be about 20K byte per sec. I wrote a QBASIC program, but it cannot keep up. My questions to the List are? 1. Has any attempted this sort of serial to parallel conversion process? 2. Where can I get a program that will read the parallel port of a PC and store the retrieve values to the hard drive? I have a bidirectional printer port and can run either a DOS app., a WIN3.1 app., or a WIN95 app. Thanks for your help. ---- Steve spam_OUTstevemTakeThisOuTtanisys.com
