I have some 8051 ICE equipment back from my initial employment in the 80s Nohau Emul51 Hardware (2 x Full length ISA cards, pod with some adapters eg DIP40, PLCC44 etc) and software (on floppies, MSDOS-based). Is it of interest to anyone or send it to landfill? -- Cheers Chris.

Hi Experts, Let me start by providing some background. We have designed an ASIC: 8051 + non standard peripherals (timers etc) + FLASH + RF frontent for a product used in wireless communications. The 8051 currently has a single breakpoint register, and we have managed to integrate with the Keil debugger (single stepping and breakpoints seem to work OK) Anyway, we are now looking at t...

I strongly suspect it is the 8051 core. It has good maturity and is produced by many many companies. Yet the 6502 onwards were more popular before the 8051 was (am I right?). What about the 68H11? is it popular at all? Ive seen many references to powerpc-based MCUs but never bothered to dive in. Are they used around much? I was opening an MP3 player at home and gave myself an exercise to...

Hi all, Recently I am stuck on my first microcontroller project. I think I have everything nailed down to the absolute last detail, but have not yet been able to find a solution to this - after about 6 weeks of looking. My 8051 microcontroller is trying to determine the ocean floor depth. To do this, it sends out a ping, enables a timer, and counts how long until the echo is returned. Si...

Hello list, Thank you for bothering to read my posting on this group. I just have one query and I would like if anybody of you answered it. I have been using the Keil 8051 C Compiler for some time now. In one of the programs I am having the output in a 2500 elements array and it seems that Keil doesn't show results of arrays beyond the 106th element or something like that. ...

Hello, I am looking for a devlopment board specifically for the 8051 family of microcontrollers. My budget is approximately $70. I want the board to help me write small/medium programs, just to start off my embedded endeavours. But of course I want it to be helpful in the long run as well. My actual ambition to create my own embedded OS because I feel that is the best way to learn about em...
