9e6c80dfbb multifunction device) for raw access, USB printer emulation, and driverless USB HID operation Industrial PCB (two-sided, 150 m), reflow soldering Plug housing, blue High-Speed LED, USB-MiniB receptacle, 25 pin SubD receptacle 3.3V design with disable-able pull-up to 5V on every port pin Three extra lines for using as 20-way I/O device (good for simple parallel high-voltage AVR programmers) Possibility for downloading volatile firmware extension code to RAM for problem-specific tasks using GPIF and true 480MBit/s New very-low-power low-voltage-drop regulator conforms to USB idle-mode power consumption limit (500A) Professional clones recommended Useful for programming devices, FPGA bitstream download, graphical LCD, medium-moving stepper motors (maybe 1000 steps per second) Number 8 In development: USB2LPT Release 1.8 Eagle source USB Full Speed (12 Mbit/s) using Atmel AT90USB168 True 5 V input/output levels, changeable to 3.3 V by a solder jumper 20 input/output lines, each direction selectable (perfect for simple parallel high-voltage AVR programmers) Easy to clone: less, cheap, widely available components, true USB design Easy to program with your tailored firmware using free C / C++ compiler Planned: MACH3 stepper motor adapter, parallel port adapter for Velleman PCS500 oscilloscope Preprogramed USB bootloader by Atmel (no programming equipment required) . This problem is on the TODO list. DiscoLitez WinAmp plugin, AD9834 DDS generator interface Even when resellers claim uniqueness, these are always the same (they lying) PCI or PCIe cards (for desktop computers): + True parallel port with ECP/EPP and expected speed Base address offset to >1000h (your software must cope with this, or you need a patch or an address-shift driver) Driver sometimes necessary, depends on operating system version and model + Cheap and easy to handle This USB2LPT: + Emulated (virtualized) true parallel port with ECP/EPP Reduced speed due to emulation and (mainly) USB bus transfer cycles (expect 10.100 times slower) + Base address same as built-in (378h, 278h) Doesn't work with programs that expect a true PnP driver stack (scanners, ZIP drives) and software that disables port access redirection (dongles) + USB available everywhere Driver necessary Driver unstable, tricky, currently not certified, currently no driver for Linux + Smart and handy cabling with thin USB wire + open-source, multi-language, extensible, life-time support Current versions There are older revisions, maybe easier to understand or to clone. Integrated bootloader for firmware update via USB (squeezed into 2 KByte of Flash ROM) Two USB interfaces (i.e. By using this site, you accept the Terms of Use and Rules of Participation . .. Yet.
