Hi Ralph,
Formatting can help alot for readability. This is explained in my noob.pdf MOV A,#55 ;A=55H MOV R3,#10 ;R3=10, THE OUTER LOOP COUNT NEXT: MOV R2,#70 ;R2=70, THE INNER LOOP COUNT AGAIN: CPL A ;COMPLEMENT A REGISTER DJNZ R2,AGAIN ;REPEAT IT 70 TIMES (INNER LOOP) DJNZ R3,NEXT Jon P.S. I received the MX-8 today, I haven't got to try it yet, but THANKS Hi Jon: I have never tryed MX-8 but its my christmas gift to you Jon. Jon have you ever seen this 8051 Simulator? http://www.computersciencelab.com designed by John Kopplin. Any way I purchased about 6 months ago. Its a whole 8051 course and simulator in one on a cd for think $20. I tryed the course it is really good and simulator is great. I just wondered if any of the engineers on this site ever used it. Do have question about it. The ports on simulator only show up as hex value on each port 0,1,2 and 3. However is their simulator that shows each pin on example port 1? My simulator does not show this. Other then that the simulator is ok for me. I started with MC68hc705c8s mcu 1995 but gave up on it because I did not like erasing the eproms and had no simulator for this chip. Any way I helped this airo space engineer write article for Radio Electronics 1995 magazine on this chip where its used as Logic Analyzer for the serial port he sent me proto type but my name was never mention in the article. I told him what he had design in the unit so Radio Electronics would publish it. When he first contacted them they turned down his article. Any way he said because I did not write the software I basically just gave him good ideas on how to improve unit. But my ideas took $75 unit and turned it into a $1000 unit. Any way thats how I got in interested in the MC68hc705c8s chip. I ask him if he ever used 8051 mcu he said the instruction set was to time consuming to learn. As he was an expert the MC68hc11 family of chips. Thats when I decided I wanted to learn the 8051 instruction set, but waited to 1998 to start as I was too busy as tech on job to learn. Tech get lot of overtime but then lose lot time with their families. Now I have the time but now I have a lot family problems you can't win. By the way I have a U.S. Cyberlab Inc kit that programs the MC68hc705c8 chip. Its new never assembled and any engineer that whats it you pay shipping it yours it worth $100. The shipping will be $10. No out of country, but if you really want it I see how much it cost to ship to you. This professional programmer made for engineers. I have it and will never use it so thats why I am offering to anyone. email rs555timer@aol.com. Its my way of saying thanks to the engineers on this site that help newbies all over the world. Best reguards, Ralph Sack |
