how to control a robot conected to paralel port?

**falleafd** · 26th March 2004 05:21 PM

No, this is the schematics of a 16x16 led. You may try to build it. You must use some transitors like this. Because, if you connect them directly, you cannot control all the matrix

1
2
3
_ A B C

If I connect the led like this picture matrix.jpg, and I want to set A1 off, so A: LOW and 1 LOW or A: HIGH, 1:HIGH

Then, if A: HIGH, I cannot set A2 LOW
if 1: LOW, I cannot set B1 HIGH

So, try it with the first picture.

In win XP, this folder contents many .dll files which are used to back up dll files in system32. If you rename this folder, win XP cannot backup dll files. If you wanna make win XP normal, rename again it to dllcache, your windows will be clear as it used to be. Now, you can use almost languages to control LTP.

In this link they give a clear detail.

The problems usually come as we need to drive a robot with the simulator running. Then we should use visual languages. This link help muchie.

By the way, this link have many tutorials on port types.

Good luck

Hi all,

U will got probelm to access parallel port on Windows XP, WIN 2K, NT.

U can use the porttalk driver from www.beyondlogic.org or IOdll from www.geocities.com/bagtool/parallel_access.html to get access to parallel port.
