Hi Is it possible to do some software DTMF /Tone detection on an ARM (LPC21xx) ? I need some links to existing code to implement this kind of DSP techniques. (i am no expert in DSP techniques ) if this type of controller can handle this. Johan

I am searching for some Xilinx programmer software for the HW-130 unit from around 1996-2000. Looking the the DOS version. The filename was HW130.ZIP Also looking for the 16-bit windows version HW130W.ZIP. Thank you for any help you can offer!

Hi, The subject of "software metrics" has limped across my desk. I don't dislike metrics for what they may show/fail-to-show. But, rather, because they usually don't have a stated "purpose". I.e., What are you trying to measure? Why are you trying to measure it? What do you plan to do with the result (besides put it in a 3-ring notebook)? I can argue many points *agains

I am somewhat confused about debugging arm processors through the jtag port using gdb. There does not seem to be a complete GPL based option. I see alot of commercial software for which I do not have the thousands to spend on and I see bits and pieces of software that looks like it could be integrated to provide jtag debug access, but nothing fully integrated. I have experiemented with imp...

Folks, How difficult it is for a software guy to learn working with hardware. I've been working on embedded systems for about 4 years. Worked on various platforms like TI DSP, Morotola, Intel x86 etc. Having sound knowledge of C, Assembly, DD, RTOS and other system level stuff. I want to learn some basic skill on hardware side (like soldering etc.) to prototype some very simple circuits....

Does anyone know if on the ADuC831, if it is possible to write to the SPIDAT (SPI I/O Register) when the chip is in slave mode? I am only asking this because I am trying to debug some software and the Keil compiler is not taking my slave writes to SPIDAT, but it would when I had specified the chip as a Master. This could just be a limitation/flaw in the software though. I wanted to check ...

Hi! I am working on a company which doesn't require a unit tests. I definently want to validate my software to myself if nobody else is not interested. Seems like I have to do unit tests with freeware tools because my company doesn't want to invest in those tools. I have been learning how to test my software, testing techniques etc. Now I would like to have somekind of measurement about ...

Hi ppl, I need to program sevetal PAL's and GAL's in an educational enviroment. I will be using a hobbyist programmer to do the programming as i do not need any large volumes. What software is available to enter the logic equations and compile to the fuse file? Does any schematic entry software exist which one can enter the schemtic and compule to the fuse map? Any sort of help on PAL...

The SIMPL project (http://www.icanprogram.com/simpl) produces an ultra lightweight toolkit useful for gluing together software programs using the Send/Receive/Reply messaging scheme first pioneered by QNX. A SIMPL application consists of two or more interacting modules. These modules can be created in a number of supported programming languages including C, C++, Python, Tcl/Tk and the j...

Any experience with On-Time RT-USB32 USB host software stack ? It comes at a reasonable price in source form ($3000), no royalties, and supports EHCI, HUBs, and some standard classes. Many years ago I used their old RT-Kernel rtos, and was pleased by the cleanliness of the code. Not that it resembles any similarity, but... I'd like to try that with the ISP1760 (if this beast really e...

In my work project, I was assigned as the firmware integrator for our digital power conversion board. We have different people working on different subsystems within the board. There aren't any problems with physically integrate each power conversion subsystem, but I would like some help with software integration. Some of the routines are very time sensitive, others moderately, and a few are ...

Hi! I am trying to implement a software real-time clock on the HC12 using the timer module. I am pretty much unable to do it at this point and was hoping that someone could point me in the right direction -- perhaps even coded examples that could serve as a way to better understand it. I need to keep track of a 24 hour day, no need for any actual dates. I can code using either assembler or...

Hi Everyone, Are there any formal requirements, guidelines, or recommendations for software which will run in a safety-critical environment in the United States or world-wide? By a "safety-critical" environment I mean an environment in which a failure can lead to loss of, or serious injury to, human life. For example, automobile navigation systems, medical devices, lasers, etc. I know...

Slightly off-topic maybe: Our company has a recuring problem : subsystems send out for cabling at subcontractors are often returned miswired. It seems that they always misinterprete our schematics. Partly i think this is because the people whoe actually carry out the cabling are not electrical engineers. The electronic schematic entry and pcb layout software we are using are working out...

I am a software engineer looking for a hardware solution that will interface with my software. I need to build a button of some kind that will emulate a USB keyboard, sending a particular character to the PC. For example, when I click the button I want it to send the letter "T" as if it was typed on a keyboard. I have looked at hacking a standard keyboard controller, but I would like a mo...

BTW, is there any good 1-wire "master" interface library (as used, e. g., to communicate with the DS18B20 temperature sensors), which happens to be free software? I'm aware of the Peter Dannegger & Martin Thomas work [1], yet neither in the code nor on the Web page can I find any permission whatsoever to reuse the code (or even to run it!) I've also seen a number of such libraries...
