Experimenting with Jim's motion software
Hi fellow builders,
Never thought that an die-hard hardware guy like me could endeavor on the software side, but thanks to Jim's website and software files including clear explanation on how to build a cheap software interface, I found out that it is actually pretty simple. I only got stuck with the GWbasic code driving the parallel port. Jim's code line 20 BASE0 = &H3BC and line 1340 OUT BASE0, DOUT seems to indicate the parallel port address is &H3BC. My PC's port does not react on this, but it does work with address &H378 . Seems that not all PC's have the same address for parallel port then?
But with this small modification the whole interface is now running perfectly, and this simple interface method opens a lot of possibilities. Lots of new things to try out !
Thanks a lot for your inspiration, Jim !
