Test Circuit for Logic Analyzer software - del20006This is a Test Circuit for Logic Analyzer software, with the Simple port circuit. The VB Logic Analyzer works, but is just an example program to test and learn.The speed at which the logic state changes say like 10 M Hz while probing even a PIC or 89C51, is too fast for this circuit. For that, the incoming data has to be spooled or stored in RAM at real time, by the external Hardware itself. As this is a Parallel Port Interface, an Embedded High Speed Digital RAM Storage of Multiple Logic input Channels with Signal Conditioning in the front end, could do the job. This is the minimum, if you want to program the rest of the instrument on Computer Software. Here is a Parallel Port Scope from picotech. Here is one you can see from Bitscope using USB or Ethernet, Mixed Signal Oscilloscopes.

The vb programs in this page works well on xp-p4 and may not work well on win98-P2. I just also made a sketch of a Logic Spooler for 10MHz Logic Analyzer, this is just a design idea for experts to improve upon. The design source is here 20006.zip. The Logic Analyzer Program dla_demo.zip . Demo Logic Analyzer 100KHz VB6 program with source code. example to get fast time in uS as vb timer min.1ms is here perftmr.zip. More Information. |
