Drop down menu the user can choose how often the screen should be updated. The choices are: update the screen after every executed instruction, after 100, 1000, 10,000 or 50,000 executed instructions.
Or, if none of these options is appropriate, the user can type in a number, then hit Enter. The update frequency may be changed while a user's program is running. Many users of EdSim51 have indicated an interest in a textbook on the 8051, based around the simulator. This book, titled EdSim51's Guide to the 8051, is now available from Amazon.com.
Read a (PDF) for free. Purchase the book from: EdSim51’s Guide to the 8051 is a comprehensive exploration of the core of one of the world’s most popular series of 8-bit microcontrollers. It begins with the very basic operations of any microcontroller, then focuses on the 8051 itself, including the on-chip timers and serial port, interrupts, parallel ports and peripheral interfacing.
All are explained in detail, with the use of many examples and diagrams. Full colour screenshots of the EdSim51 simulator are embedded throughout the text, illuminating the topic under discussion. In this way, the reader gets to see exactly the effects a running assembly program has on the controller’s registers and on the attached peripherals.
The reader is encouraged to download (for free) the simulator from and try out the book’s many examples. The penultimate chapter contains many more examples in assembly, designed to exercise the simulator’s peripherals, while the final chapter contains an example written in C. This C program contains a driver for the HD44780 LCD module, designed for writing to the module as interfaced to the simulator.

I'm currently learning the basics of microcontrollers and was given the task of creating a scoreboard to display on the LCD (so 4 digits) and have switches to increment and decrement each displayed digit in assembly. So something like: 0000 Switch 1 and 2, decrements and increments the first digit, 3 and 4 for the second. So on and so forth.
Hitting switch 2 from this point would show: 1000 Switch 4 woudl show: 1100 Etc. I've figure out how to output to the LCD (thanks to the edsim51 examples) so that my program shows '0000' when run, but I'm not sure how to implement the rest of my code. I'm not asking how to be spoon fed how to do it but more like I could use some guidance. Would it be possible to use the 'switch banks' on the screen to do this? There ARE 8 of them. And do I have to use interrupts to increment and decrement the counters?
If it's of any help here's the code I have written to display '0000' on the LCD:; put data in RAMMOV 30H, #'0'MOV 31H, #'0'MOV 32H, #'0'MOV 33H, #'0'MOV 34H, #0; end of data marker; initialise the display; see instruction set for detailsCLR P1.3; clear RS - indicates that instructions are being sent to the module; function set CLR P1.7; CLR P1.6; SETB P1.5; CLR P1.4; high nibble setSETB P1.2; CLR P1.2; negative edge on ECALL delay; wait for BF to clear; function set sent for first time - tells module to go into 4-bit mode; Why is function set high nibble sent twice? You should start by putting you display code into subroutines. One to initialise and a second to display the string at 30h There is no need to use interrupts yet. Poll (read repeatedly) the 8 buttons in turn, it will be easiest to wait until a key is pressed and released. The method is quite simple. If an up key is pressed, increment the value unless it is already at '9'.
If a down key is pressed, decrement the value unless it is already at '0'. Every time a key press is found, refresh the display. Would it be possible to use the 'switch banks' on the screen to do this? There ARE 8 of them. Reiniku Sorry, don't know what they are.
Reiniku Nov 29 2010, 7:54 PM The original idea was proposed as: 'The idea is to display the count on the LCD display. Using switches, a user can increment and decrement a counter.
After every press of a switch, the subsequent count can be seen on the LCD display. There are 4 counters that have to be seen on the LCD. Use two switches per one counter: first switch as incrementer, second as decrementer.' So far all I have is the digits displayed on the LCD. I'm very very new at assembly so I'm not really sure how to continue. I have the code written listed above.
I'm fortunate since this is all done on edsim51 to simulate 8051. It's part of the supplied tools given by my intrsuctor with its manual.
The whole class is to use edsim51 so we are streamlined and can compare code on our different projects as we progress. The problem is that we were instructed to use this but not HOW to use it, so I've been lost for quite a bit.
It does recognize db when used in this manner LEDcodes:; this label points to the start address of the 7-segment code table which is; stored in program memory using the DB command belowDB 11000000B, 11111001B, 10100100B, 10110000B, 10011001B, 10010010B, 10000010B, 11111000B, 10000000B, 10010000B. The sample that Majoka provided seemed very interesting and used interrupts to increment the counters.
I was hoping to get it working so that I could learn from it thoroughly. Reiniku I'm sure you would learn a lot from this code, but it may take time to get it converted to suit Edsim, and then you will need to make a lot of changes to suit your task. My initial post with the display code does only display a set value (in this case '0') and I have no idea how to create a way to increment or decrement the value. Reiniku Just increment or decrement a single memory location, there are a few ways but INC 30h is the simplest, where 30h is an address.
Try to use address other that 30h,31h,32h,33h for your memory as you may get confused with the ascii digits 0,1,2,3 which are also 30h,31h,32h,33h. Hi Reiniku how u change that DB format i download edsim its looking like nice graphics How would I go about doing this while edsim is already running and increment/decrement the value on the fly? Select two pins for push buttons as signal on push buttons becomes low then increment or decrement as u want during run time send a low signal to pin ans see is it do that or not u can download Proteus if u want 1) 2) and portable version also here http://www.8051projects.net/forum-t39541-0.html.

Do you want to learn about microcontrollers and embedded systems? Are you studying the 8051 microcontroller? Do you want to test your code for communicating with peripherals without having to first build the hardware?
Edsim51 Tutorial
Are you teaching an embedded systems course and would like your students to have access to a virtual 8051 training kit? If the answer to any or all of the above is true, then you’ve come to the right place. The EdSim51 Simulator for the popular 8051 microcontroller is exactly the tool you need. And it’s FREE! A virtual 8051 is interfaced with virtual peripherals such as a keypad, motor, display, UART, etc.
The student can write 8051 assembly code, step through the code and observe the effects each line has on the internal memory and the external peripherals. The Virtual Peripherals:. Analogue-to-Digital Converter (ADC). Comparator.
UART. 4 Multiplexed 7-segment Displays.
4 X 3 Keypad. 8 LEDs.
DC Motor. 8 Switches. Digital-to-Analogue Converter (DAC) – displayed on oscilloscope Why EdSim51’s Simulator and not some of the many other simulators that are available?
Many of the simulators for the 8051 that you will find are industry-standard. They are used by professional 8051-based embedded systems designers. While they show the state of the registers, memory and the port pins while code is being debugged, they do not have graphical representations of peripherals that can be used interactively to communicate with the 8051. EdSim51 have filled that need.
The student can learn how to scan a keypad, multiplex 7-segment displays, control a motor and count its revolutions, etc. Buy in Aliexpress with free Shipping in the Worldwide.
