You can try Avocet. I used their stuff donkey years ago on DOS. Was quite useable then, no idea how they are now. Look at http://www.avocetsystems.com/company/techshee/asheets/8051.htm They have a downloadable demo, so you can see whether it will work for you or not. Regards Anton Erasmus

Other variations in the 8051 devices are more complex: - Dual or multiple DPTR registers, with various SFR-based methods for selecting the active DPTR (some devices can even auto-switch, toggling the active DPTR choice after each MOVX...) The 80320 has dual DPTRs. - SFR-controlled MOVX timing, dynamically adjustable as the program runs. - Nonstandard "unified" address mappings, for example letting MOVX instructions access internal data and SFRs. -- Niklas Holsti Tidorum Ltd niklas holsti tidorum fi . @ .

You will need the Keil simulator. There is nothing else to touch it particularly for the Dallas cores. Keil worked very closely with Dallas during development of the parts. AFAIK none of the other simulators come close as the Dallas parts used many extensions to the hardware. BTW There are over 50 different 8051 family cores with different timing and extensions. >It needs to: >- run on Windows, All do >preferably Vista but failing that, XP :-) It was Vista that failed. >- be free or a lot cheaper than the Keil package, which I would use if >I could justify it for this project. Sorry but the "free" stuff is just not going to cut it for these parts. It is not a standard 8051 core. Where most do a reasonable simulation for the standard cores the Dallas parts had a lot of extensions. Also all the free/open source/shareware tools are going to be quite old I would think as the circus moved on to ARM years ago. SO I doubt you will get anything that is Vista compatible except by luck BTW which compiler are you using? You will need a compiler that will output the relevant extended OMF debug files. Otherwise you will be debugging assembler not C. -- \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ \/\/\/\/\ Chris Hills Staffs England /\/\/\/\/ \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/

No. IF you want to use a free/cheap set of tools you will have to restrict yourself to the "standard" 8051 parts with no major extensions. -- \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\ \/\/\/\/\ Chris Hills Staffs England /\/\/\/\/ \/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/
