Hi, I'd like to write a little app to allow a PSP to be used as a "wireless display/terminal". I've already developed a suitable framework for the PocketPC platform and would like to try for a common framework that I could extend to things like PSP's, small tablets, smart phones (e.g., winmobile), etc. Any pointers to SDK's, etc.? The hits that come back from search engines seem to b...

I've just bought a Humax Digital Video Recorder and it has a USB 2.0 interface to allow saved films to be copied onto a PC. However, it is upstairs in my living room and my PC is in the basment and I don't want to run a cable down there. Humax's PC software will only work with a USB port so it would need to be a USB to USB link. Although, thinking about it, it is possible that the Hum...

Hi, I currently have a kiosk application that I would like to port to a wireless, *portable* implementation. So, small tablets or (ack!) smart-phones (with the phone functionality permanently and irreparably disabled) seem a good choice. Phones being better suited in terms of size (want to tuck this into a shirt-pocket while not in use). But, I rely extensively on barcodes to provide...

I have an application where I there may be several automatic pedestrian doors (the sliding and swinging doors you see in airports, supermarkets, department stores, etc.). Each installation shall be able to communicate to some gateway/logger/concentrator/router, whatever you call it, whether it be via CAN, RS232, and one day, even wireless, to the gateway. This gateway then will communicate...

Hi, I have a modest sized distributed system (~100 processors) that I am trying to protect against intentional acts of sabotage, theft, etc. [The current implementation is *wired* though that will probably change in the future to a hybrid wired/wireless approach. I'll deal with those issues, later] I am not concerned with intrusion *prevention*. The stacks and protocols are hardene...


Long distance comms

Hi I have a requirement to communicate between a slave device and a master where the distance between them is approximately 3km. I don't need high speed comms, 10-20kbaud is sufficient. Unfortunately I don't have the luxury of being able to use repeaters, fibre optics or wireless. If RS422 was spec'd beyond 1.2km then that would be ideal. It seems that CAN will work up to 6km at bit rate...

Hi Embedded Group- I'm having a problem with my Lantronix WiPort module and I'd like to hear some non-Lantronix advice if that's possible. I'm not an experienced user of wireless hardware and software. I had a very early WiPort on a WiPort eval board from 2004. It stopped working after a few hours of use (WLAN ACTIVITY LED is held steady on whereas it would flash when it worked). ...

Hi, we have been doing a lot of work with normal XP/2000 installs. Ideally we want to ditch harddisks and run off flash disks... so we have bought some x86 embedded boards with Embedded XP images, however we have asked our supplier to make changes (such as add certain device drivers for 802.11 wireless etc) but they are charging a small fortune each time. It would be nice to have a smaller...

Hi, Is there any difference (hardware-wise) in the "radios" (chipsets) on the AP end of a 802.11b/g/n link and those on the "client" end? I.e., is the difference merely one of antenna gain, Tx power and *firmware* (meaning software that conceivably *could* be rewritten vs. software that is deeply and immutably buried within the chipsets)? Said yet another way, could 'n' PC's with wire...

I'm looking for suggestions for a microcontroller for use in an audio player. This is going to be for a high-end player, not a mass-produced portable, so I'm not bothered about size or power consumption, nor am I worried about getting the lowest possible cost. It needs to have Ethernet for connecting to the outside world. Some support for wireless networking would be good too, if poss...

The conductive paint is very flexible (I put it on my hand which flexed a lot ) and there seemed to be enou...
