    Any decompilers available for AT89C2051 HEX code?

    Re: Any decompilers available for AVR HEX code? Thanks for your help. I just noticed that I made a mistake in the header line... will try to change the header line. It should be a HEX decompiler for AT89C2051 code... Any luck with this?

    How to use *.abs files for AFT16V8B?

    How to use *.abs file? I'm not very familiar with PLD's. I have received an *.abs file which is supposed to be loaded in a AFT16V8B. Till so far I have figured out that this is a file used for simulation purposes generated by the compiler. So, I would like to: - convert this to readable...

    Problems with hysteresis as soon the ADC reaches 255

    Re: Need help with PIC asm That looks stupid. I already asked this question... Had to ask the next: It works as you described. I do get some problems with this hysteresis as soon the ADC reaches 255, then it will go to 0+. Same happens if the ADC reaches 0 and I do this comparision. Sorry...

    Problems with hysteresis as soon the ADC reaches 255

    Need help with PIC asm Please give your advise on next problem: I read in an analogue value. I like to switch 4 outputs on predefined levels. Problem is that the output is blinking very fast as soon as the ADC reaches the prefined levels before it goes on steady. I think some hysteresis must...

    Which is the best BASIC compiler for PIC Micro

    I found a reference to a basic compiler/simulator in another post here at elektroda. I tried with some small simple code to see if it produces too much asm code, or does it do things diffrently from what I would code in asm. I can say that it produces almost the same as I would code myself in...

    How would you control DC motors?

    Hi Flatulent, Have you seen any sample of circuits (boards) of this? Which FET's would you recommend? What about the PCB design, tracks etc? All info is welcome.

    How would you control DC motors?

    Need to control DC motor of ~300W at 24VDC (~13A) and in some cases on 12VDC (~25A) with reversal from PIC micro. How would you do that saving cost and space?

    How to make a SMPS with input 230-500VAC & output 24V/2A

    24v smps I know very little about SMPS and need to make a reliable SMPS with these data. Input voltage can vary from 230VAc to 500Vac (230,380,440,480 500). Output should be 24VDC at 2A. All schematics or tips are welcome. THanks for your help.
