inital results on error correction

While I have yet to actually implement the full-scale error correction as I want to, I did some manual tests today. I basically took a track that I was erroring out on, and swapped in 1-bit away values for the bad bytes.  In some cases, it appeared...

example files

I wanted to put up some example files. Note that a preceding “D” for dump and two delimiting 0xFF’s might exist in these files. Also an ending 0xFF 0xFF might exist. So two bad files below have exactly...

I’ve played around a considerable bit from yesterday. There’s something very strange about the speed the PC can react in certain circumstances, and I can’t quite nail it down. Now I haven’t...

java and portability

While I have some experience with Java, I’ve never tried to run my stuff cross-platform. Never a real need. While most of the Java stuff has yet to be written, I took some basic serial code and GUI stuff, and...

Finals week at pitt.edu

Welp, this is finals week, so don’t expect anything new to show up until after April 28th, 2005. But, this doesn’t mean I’ve forgotten about this project! I am very much interested in moving this...

Timing problems still?

I think I’m still having timing related issues. I have RTCC overflowing every 1.8us which I *know* is less than the 2us bit cell(or less than half the bit cell, if you take it to be 4us), but this seems to be what...

too many variables

I think that’s really the problem I’ve been facing with this floppy project. Trials and tribulations indeed. Or at least trial and error, with stress on the error part. There are probably less than half-a...

java software updated

Tonight I’ve finally got around to adding a config file option so that you don’t have to keep selecting a comport to open.  It also remembers your “number of retries” before skip options. Simply...

review of timing details

I set up a couple more hardware flags on my software so I could see things like, edge detections vs rollover detections vs PC transmissions, etc. It all looks perfect to me. I took maybe a dozen different samples...
