Assembly error problem

ymouse999

The subject of the course design, the prawn helps. . .

The purpose of software design is: common in industry-microcomputer temperature control system

The software includes the following:
1. The beginning of the program, including the setting of the scale constant table and the settings of the segments, the allocation of the pre-stored temperature and the storage unit of the calculation results.
2. Input and storage of set temperature and alarm temperature.
3. System initialization.
4. Analog thermoelectric digital signal input.
5. Scale conversion, convert the thermoelectric potential signal to the corresponding decimal temperature value.
6. Temperature display.
7. Preset temperature comparison, and display heating, insulation or alarm respectively according to the comparison result.

Design principles
  The temperature control system is completed on the 586 microcomputer. Use assembly language to compile the source program. According to the working principle of the A / D converter, the 8-bit binary in the range of 00 ~ FF represents the 0 ~ + 5V thermoelectric potential signal provided by the thermocouple and amplified, and input from the keyboard. According to different thermocouple indexing tables, the digital signal input to the computer is scaled and converted to a temperature value corresponding to the temperature thermoelectric potential and displayed on the computer screen, and heating and heat preservation are given according to the set temperature. And alarm information. Master how to use computer to realize the collection and control output of industrial furnace temperature.

Haha, it turned out to be X86, and didn't even say anything wrong? Have you read it seriously? I’m sorry, I can’t show it to you. Come on, I’m also a student, I’ll push all the problems and you can help me solve them.
At least you can write your analysis. You can write program comments. This shows that you are sincere, and then others will read it quickly, so they can reply to you. If you give the debugged code directly to you, it won't do much except earn credits for you? This does not seem to be the original intention of verysource...

It turns out that I was wrong. You have a simple comment. It doesn't seem to be programmer's comment style
I only have masm32 here. I am in a hurry to take the exam and let the later masters correct it. If LZ sees it, write down the wrong place...otherwise it will be difficult to find all the errors for you...

Laziness is affirmative, but I didn’t say that I just didn’t want to mislead other people. My thoughts have fallen into a dead end (about this procedure), so I only left the title. I hope you have something to say. What, maybe it will help!
