Microchip PIC
USB Mass storage device on PIC
15. February 2009 - 16:25 — adminMicrochip's microcontroller applications can easily support USB Embedded Host functionality. One of the most common uses of this capability is to interface to mass storage devices, such as USB Flash Drives and memory card readers. These devices utilize the USB Mass Storage Class.
Random bit generator
3. February 2009 - 21:43 — adminSimple, low-consumption and really unpredictable random generator, usable for cryptographic applications.
Open Programmer
23. January 2009 - 22:10 — adminAn open source USB programmer for PIC micros, I2C EEPROMs, some ATMEL micros, generic I2C/SPI devices...
ds30 bootloader
10. January 2009 - 19:30 — adminds30loader is an 100% open source bootloader for the Micropchip dsPIC30F family of digital signal processing microcontrollers. It supports all devices out of the box, only minor adjustments need to be done in firmware.
UBW32
5. January 2009 - 19:37 — adminA 32bit version of USB bit whacker - more pins, more memory, more power, more fun...
PIC12F675 video game concept
2. January 2009 - 17:08 — adminAll PONG game is controlled and run by 8 pin PIC12F675 microcontroller that is clocked with 4MHz internal clock generator.
Simple CPLD dev board
22. December 2008 - 22:34 — adminA home-etchable, self programming development board to get you started with the CPLDs.
Web server on a business card
16. December 2008 - 2:56 — adminThis mini web server is slightly smaller than a business card. There are a lot of tiny one-board servers out there, but this is probably the smallest you can etch and solder at home. Unlike many embedded web servers, files are stored on a PC-readable SD card, not in a difficult-to-write EEPROM.
The Bus Pirate/Universal Serial Interface
15. December 2008 - 8:07 — adminVery cute idea I like – a universal bus interface that talks to most chips from a PC serial terminal. It deserve to rework!
