They can be used to -self-program the flash memory (taking care not to overwrite themselves). Instead of a hardware programmer you can use an available communication port (such as the serial port) to upload new programs into the controllers flash memory. text/html 2010-07-29T15:35:44+02:00 edwin http://wiki.edwindertien.nl/doku.php?id=boards:ottantotto&rev=1280410544&do=diff Introduction The idea behind this board is: build general purpose Arduino but very much lightweight (similar to the bare bones). Skip the form factor, but make it possible to connect sensors and servo's directly. Make it possible to use in breadboard, but also as small standalone module. Make it flexible, yet as compact as possible. It is by no means meant as competitor to the standard Arduino boards, it is tailored for easy building (few parts, all trough-hole) and easy connection (lots of con… text/html 2010-07-29T14:08:57+02:00 edwin http://wiki.edwindertien.nl/doku.php?id=software:xbee&rev=1280405337&do=diff Introduction This page describes simple hardware and software for a wireless sensor using Xbee modules. Electronics * PC side: Xbee on USB adapter by parallax * Arduino side: XBee on adapter by sparkfun The PC-side XBee has been programmed using the ZNET 2.5 coordinator firmware (using X-CTU, digi's configuration tool under Win XP). The Arduino side XBee has been programmed using the ZNET 2.5 Router / end device firmware. text/html 2010-07-29T13:08:17+02:00 edwin http://wiki.edwindertien.nl/doku.php?id=modules:opticalmouse&rev=1280401697&do=diff Introduction Sensors from optical mice work as incremental encoders and camera-in-one. A lot of these sensors have an SPI interface which makes interfacing to a microcontroller system relatively easy.
