Post by thread:[PIC]: PC based transition recorder?

Resending with tag! Anyone have a DOS program that I could use as a data transition recorder? I wrote one a long time ago (under CP/M). I want to watch a parallel port (in input mode) for changes on the 8 data lines. On any change, the new value would be stored in memory. When the program is stopped, the data would be saved to disk as 8 bit binary, eight ones and zeroes per line. I could then print the whole mess out and see a long string of SPI commands. Or, any other sort of SPI monitor would be great! THANKS!

Harold, I have some source code on my site which enables you to display the contents of the parallel port on the screen FWIW. It's written in Borland C with lots of comments. http://www3.mistral.co.uk/brian.clewer/code.htm Regards, Brian {Original Message removed}

Thanks! That's a start. The hardware people just built another unit and everything started working, so I may not need to do some deep SPI recording... But, I'll keep your notes and adapt them to my needs should the need arise! Thanks!
