but with the aid of a Windows driver for your EPP-mode parallel port, it goes pretty fast. At about the time USB was catching on, some digital camera makers were providing drivers for interfacing their cameras. Since USB is so much more convenient from the cable size, weight, and cost standpoint, it isn't rocket science figuring out why parallel ports aren't so much in use these days.
Some drivers use the parallel port at full PCI speed, whatever that happens to mean, but the days of software-timed interfacing are gone, hopefully forever. That doesn't mean they're a bad thing in the MCU environment, but for computers of varying rates, with varying amounts of memory, with varying CPU types ... <sigh> ... it just doesn't fit. RE |
