am converting an old laptop into a digital picture frame. My thought was to create a small XP (nlite) with the apps I need (slideshow, wireless, vnc) on a hard drive and then copy it over to a CompactFlash which I would then replace the laptop harddrive with. I've got a nice tight version on a hard drive (under 500Mb) ready to put onto CF. Problem: it doesn't appear that the BIOS I have wi...

Greetings, When an embedded wireless system has a an image sensor, what is usually used to compress the image for transfer over a GSM network similar to a cell phone unit? - Do cell phones/devices have dedicated hardware (FPGA,DSP)? - Is the compression done in software? I am guessing that would need a powerful MCU that will consume a lot of power I am a new at this so any inf...

Hi, I'm a student working on an embedded systems undergraduate design project. In our project, we want to use an Atmel chip with some other Zigbee module that will allow us to transfer information using Zigbee wireless communication. We have found several choices, such as Maxstream's XBee Zigbee module, but we would prefer to use one that is from Atmel or is compatible with Atmel. We...

So for my capstone project I've decided on a myoelectric controlled (think robotic prosthetics) wireless computer mouse. From my little reading so far, I can avoid the pc side of the bluetooth stack entirely by conforming to the Human Interface Device profile on the device side. The way I read it, it should be basically connect and play, no drivers needed. I have some decent info on the analog ...

Hi, Let's say I'm developing a control system for a UAV and I've decided to use Linux with RTAI in the vehicle. I have a real-time task which does the actual actuation of the flight surfaces and it controls the hardware (motors) through GPIO pins. The RT task is talking to Linux through a fifo (which Linux processes see as a block device) and Linux has a device driver for a wireless ...

I'd like to use an inexpensive micro-controller (like Atmel's AVR -- I like the Butterfly demo board but would like other suggestions). And then add 802.11 for broadcasting temperature readings. I saw a few serial-to-WiFi devices, but they're all > $100. Yet I can buy a USB-> WiFi dongle for ~$15. Still, many micro-controllers don't support USB either and I don't want to run Linux (unless ther
