With this new FPGA solution, certain tracks would result in what I call a “short read.” A short read is any received track that contains less than 28,125 delta T’s, aka pulse times. Given a certain...

characterizing speed performance of floppy drive controller
So I’ve got things working rather swimmingly right now. Switched drives from Samsung to Sony, and it’s made a huge difference. The Sony just seems to work better. I’m averaging about 355ms per track...
created testbench for state machine / block ram tester
So tonight I fooled around with ISIM, which is Xilinx’s simulator. I was doing behavior simulation and wrote a small testbench for the block ram state machine that I wrote a few days ago. Really neat stuff...
SX EOL
I hate when this happens. 🙂 The Parallax SX microcontroller line has reached production EOL. The owner of the SX design (www.ubicom.com) has given Parallax final notice that we are to place a lifetime buy of wafers. We...
bought a Saleae Logic. Another tool for my toolbox
I bought at Saleae Logic which is an inexpensive logic analyzer. See link here. It isn’t nearly as fast (only samples at 24mhz max), and it doesn’t have as advanced triggering capabilities, but it does do...
got build environment working again, fixed uart code
So awhile ago I bought a quad core machine which runs Vista 64. Once I had the new machine, I tried getting my build environment for the AFP working again. NetBeans, the java IDE I use, has 64-bit support but there...
