Hello, the very old timer intel 8253 and 8254 could be used in mode 1 as a hardware triggerable one-shot with programmable pulse length. Now I am using the infineon 80c167 and need a one-shot with programmable pulse length and hardware triggering too. There are a lot of counters T1 to T8 and there is the Capture/Compare unit too, but I found nothing about one-shots in the user's manua...

Hi Everyone, I am now using a PC104 (model: nano-4386A, vendor IEI world), which will be running linux. Now I installed fedora core 6(kernel 2.6). but COM1 does not work at all. I have installed winXP on the same hardware platform, COM1 works well. So the hardware is OK. Here is detailed info. (1) hardware configuration: NANO-4386A, Pentium 1.6GHz, Sandisk 8GB CF card, 1GB Ram...

Hi Friends, I am a new bee in embedded systems. My task is to test a filter(low pass) with audio in and out connections of hardware board. I have developed a low pass filter in C and tested it using goldwave(signal processing tool) and need guidance on how to test the same filter with audio in and out connections of hardware. Thanks in advance. Aamer

Hi - does anybody know of any ARMs with a built in hardware divide? I heard that a new core coming out would have a built-in hardware divide, but I've been unsuccessful in finding out which core that is and if any chips have that core. Thanks, -Michael J. Noone

All, I have been handed a project to locate and obtain a replacement for a now obsolete single board computer, a win systems SAT-4DX. Win systems recommend a newer one, but there is a compatibility issue with the target hardware that the computer connects to. The target hardware utilizes the PC-104 (ISA bus) to memory map hardware into the 15-16Mb range. The new PC has a minimum of 32 M...

Hi to everybody, We are planning to switch luminary micro from silicon laboratory 8051 + Keil C51 compiler. I need suggestion for following points, 1. Is there any luminary micro specific hardware debugger adapter available which will support many IDE's ??? 2. For testing software development tool like IAR, Keil, RealView will I need to purchase their hardware debugger ??? Please s...

The LOOPGEN IP collection provides fast hardware architectures for implementing nested loop structures. The collection comprises of three different architectures (variants), namely: - HWLU, a mixed-level structural/RTL architecture, - IXGENB, a behavioral-level and - IXGENR, a high-performance, pure RTL description of a more generalized form of the architecture. Hardware looping archite...

Hi all, I learn computer from colleague and all my development experience is on desktop computer. I want to do something new. I want to begin to do interface with hardware and, hopefully, can do something useful (say, to make a simple toy). I don't know how to start and I need you suggestion/help. Say, where/what hardware should I buy? And how to "program" those little device? Any knowle...

I am using IAR Workbench w/ JLink & have been thinking that Jtrace capability would be real useful. Unfortunately, JTrace is ~ $1300 for the hardware. Is there any open source or 3rd party Jtrace hardware around? I'm using NXP LPC 2300 chips mostly. Thanks, Tom

Hi, Does anyone know what hardware device a mobile has? I want to start some software development for mobile phone hardware, but having difficulty finding the right one for me to start with. Can anyone please recommend a mobile device, contains a LCD like Nokia N91. If Nokia N91 is hard to program with, what other device is easier? Which system development kit I will have to use for mob...

I hacked together my "IP cameras" using some web cams for which I was able to track down some FOSS i/f implementation documentation. This was OK for a proof of concept. But, I now have to settle on "production" hardware. There seem to be a variety of i/f's for cameras: - RS170 (requires hardware to digitize the signal; inflexible) - parallel (video is digized, just needs to be captured a...

As a coder I've usually had custom hardware to work with and the choice of architecture etc has been cost-driven and set in stone long before I start trying to debug the board... but I digress. I have a potential project coming up, where I may have some influence on the hardware. The spec is of necessity still slightly woolly, so my apologies for that in advance. The basics are inpu...

Hi All, From my limited understanding the physical interface is the same between the SD and SDHC except the read/write speed is much faster... My ARM9 cpu has SD hardware ... but what is needed to impliment SDHC..... is extra hardware required or only software driver. Thanks in Advance Joe

hello guys I want to ask one basic thing about the bootloader. as bootloader is the first program which runs on the machine and initialises all the process and the hardware before passing the command to the operating system. But what I want to know is that how it bring up the board , I mean when we push the power button bootloader gets staarted and start doing it's job. So I want to know ...

Hi all What would be a good choice for low-end embedded hardware (single board systems à la raspi, cubieboard) with good support for USB slave mode? As in there is USB hardware onboard that can be configured to run in USB device / slave mode and there is kernel support for it; as in gadget driver. I gather this mode or something like it was / is supported on the early RasPi model

I am working on a prototype chip using electron beam lithography near the technique's limits (10 nm wires). I need to bridge from the chip to the PC world and need some embedded hardware. I am a biochemist and programmer (with an MBA, so I am a 'suite' who wants to grab a soldering iron) and while I have studied IC fabrication for a number of years, much of the stuff is still pure voodoo to me. ...
