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 were a host of issues regarding FTDI drivers, jd2xx, etc which I fought over [...]
my checksum algorithm
So I’m using an XOR checksum to detect errors in the transfer between the SX and the PC. I always thought it was a reasonably strong checksum, even though it’s still an 8 bit checksum.
I found a neat article today here.
“The XOR checksum has the highest probability of undetected errors for all checksum algorithms in [...]
About techtravels.org
This website mixes a few of my interests: travel, photography and technology.
I have two different photography related sections. The first section, Travel Snapshots, is a gallery collection of travel related pictures. Most were taken prior to my Great Awakening in the wonderful hobby of Photography. These pictures were designed to preserve the memory of our vacations and were taken with a Point and Shoot camera in Auto mode. They were taken with a Canon Digital Elph and a Fuji E900.
The second section, my Portfolio, contains photographs where I have paid attention to the details. These photographs weren't haphazard results from putting a camera into Auto, pointing it, and releasing the shutter. I'm still a beginning amateur. While I have the important basic concepts down solid, I'm constantly honing my skills, especially in the composition department. These were taken mostly with my Nikon D300.
I plan on adding a section on Photography Tips and cover a wide range of different topics. I've read quite a few books, and learned what to do, and what-not-to-do, and I'd like to put together short essays.
One of my other interests, technology, has manifested itself on this website as primarily my Amiga Floppy Project. This project involves building an external Commodore Amiga floppy drive controller that attaches to a PC via USB, and allows a standard PC floppy drive to read amiga formatted floppies, and create .ADF emulator images. It uses a Parallax microcontroller called the SX28.
