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 ...

Hello to all, I m working on the wireless product which is having the DSP, ADC, WLAN chipset, LCD, ect. Now as a part of this project, i m working on the Power ON Self diagnostic test for all the major components. In our project the ADC is not yet finalised but it is 16 bit SAR type. Is there any standard procedure to test the functionality of ADC, like memory testing. Could any one please...

Hi Group, I have a connectivity problem to resolve for a prototype project. The controller is already installed: a 386 type running ROMDOS. The ONLY connections available are serial ports and one parallel port configured for digital I/O. I need to connect to some serial port devices as well as monitor and control some other devices via discrete DI/O. Currently I run physical wiring but ...

Has anyone here heard of or tried the Telit GM862-GPRS module? This offers the TCP/IP stack included with the wireless GSM module and supposedly one can connect wirelessly to the Internet with a simple serial port connection and AT-style commands. I guess what I'm really wondering is will these units work in the US? I've sent emails to Round Solutions ( http://www.roundsolutions.com/uk_p...

Hi, I would think I have enough DSP knowledge and experience as a DSP firmware engineer. I even completed a WiFi physical implementation project, i.e. I know the WiFi packet structure etc. I also know basic TCP/IP, UDP definition and its application in embedded systems. My problem is about programming on WiFi or Bluetooth for an embedded system. I have quite several DSP evaluation board...

Hello, I'm starting now a project where I have to build a little file system on a Serial Flash. Mainly, the stored files are to be transmitted to a Control Unit through any proprietary wireless link and I have not any special requirements to this file system. But it is required to allow also USB access to this storage,i.e. PC to be connected to my MCU via USB and my MCU is to be connected ...

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

My company makes an embedded device which normally is controlled by a wintel host via RS232. The communication method is 8-bit binary, packet based, with no hardware flow-control (3-wire interface). I now have a new requirement: My device must communicate with a bluetooth enabled wireless host. The host may be either a bluetooth enabled wintel box(running winxp) or a PocketPC(windows CE). ...

Any experience using handheld external displays to enter/display data in the field for an embedded device? Whats easist to get up and running? RS-232 or USB communication ok, wireless less ok. I suppose options off the top of head are PDA's, palm computers, smart cell phones, gameboys, or maybe they sell custom display/keyboard/communication link only units for this purpose?
