I am looking to design a current limited, 2-6A, power supply controlled by a PIC. Consumer electronic "smart microprocessor" battery chargers seem to know how to regulate the current. Any thoughts?

My company has a device that uses the 89C51. Somehow the flash memory is getting corrupted. The device will not boot properly after a reset. When the device is reprogramed it works ok. I know this is a general description without much detail. I'm just looking for anyone who might have had similiar problems with this device. Thanks! E.L.

hello members... realize i cud be a little off topic here.... just banking on anyone of u having used it before... well, am trying to pick up a Microprocessor for one of my projects.. after much deliberation, have settled for MCF5249 - ColdFire series... I have also downloaded the Crossware Development suite for Windows... There is not a great deal of help from the software on how to r...

I have a basic acknowledge of PIC. And I take OS, Logic and Computer Design, x86 Assembly in university, and wrote some codes on experimental board (processor 80386). Now I want to go deeper on embedded systems. But i don't know where to start. e.q. Which microprocessor should i select? Which books are for me? Thanks...

Hello all, Caution I AM A NEWBIE!!! Be gentle, ever so gentle!!! I am currently trying to create a communication protocol that will connect several microprocessor devices together. The devices do not exist yet, because I have not designed them yet. In order to keep my sanity, I would like to store all the data in the same memory location for each of the devices such as firmware number, pr...

Hi, I recently posted asking about ethernet on eZ80 microprocessor. Is there a better processor to use? I spoke with an engineer at Zilog, and it appears that working with the MAC layer directly is going to be extremely difficult. Are there any microcontrollers that are better suited for this task? I need to run it in promiscuous mode, which is also a problem with the eZ80 because it can actu...

Hello, I've done some PIC development before, with the PIC16F690, PIC18F4321, etc. and I'm thinking about trying out the Atmel processors since I've heard they have a flat memory space (no banks), a software stack, and other things I am interested in. What would be a good entry level atmel microprocessor to experiment with (maybe having features like USART, SPI, USB, external data/program ...

I've never used ARM microprocessors, so i have questions about. For now, i have only used 8 bit micropoccessors and i have programmed only in C and asm language (i'm not expert in object oriented programming). I shoud use an ARM7 microprocessor. 1)What is the best ide for software development?Any site, reference , comparative table, suggestion? 2)Any book about this micro? I'm totally new, ...

Hi everyone, I am a newbie here. So some of the queries might seem inexperienced. Also, I am a little inexperienced about embedded systems. So please bear with my stupidities sometimes. What I exactly want to know is something like this. I am building a UAV and I am having some problems in controlling the speed of the fans (its a quad rotor flyer). The digital signals that I send through my re...

Hi all, I'm new to the group, and to the micro world as well. So, please forgive what may seem like ignorance on my part... I have recently aquired an EVB (nmix-0020) that utilizes an HC6811 microprocessor. I have been able to find some documentation on this, but the schematic that accompanies it (via the web) is very blurry. I have hunted for this information for what seems like hours (...

Hi, I am new to using lwip. I am wondering if you can advice me on the same. I need to transfer data from PC to Microblaze microprocessor on a Xilinx FPGA board and vice versa as fast as possible. i dun need any error correction or the overheads like full TCP/IP. I am currently readin this article to understand about socket programming as an initial start: http://cscene.unitycode.o...
