The paper aims to implement and simulate a prototype of industrial multiprocessor communication systems through serial communication RS-232 protocol using an 8051 microcontroller. The created model is used for experimental purposes by the microcomputer trainer (MTS-51). Many simulators are present for the 8051 microcontrollers, many of them do not support multi microcontroller communication, or simulate all the embedded peripherals. A few of them can simulate external peripherals. The proposed simulation has been accomplished using the PROTEUS program. In this work, the RS-232 serial mode of communication using an 8051 microcontroller is used, with an emphasis on interfacing it with an LCD screen and a hex keypad, stepper motor, speaker and a seven-segment display. The operation of several microcontrollers in the master-slave configuration is explained. It is verified that both the stepper motor and speaker is controlled at each slave using the master controller. The used communication protocol is a very simplified one, highlighting how simple such communications are accomplished in high-tech industrial environments. Moreover, perfecting the use of the RS-232 for transferring small blocks of information has resulted in simple use and support of the maximum number of communicating processors.
Hello guys, Im in college atm and I own an macbook air and I want to code an 8051 microcontroller. The program I was suggested to use was Keil, but sadly it doesnt have a version to mac. Im here to ask for your help because I really need to find another way to code my 8051. The Parallels Desktop program is really expensive so I was trying to find any program that would have an mac version already.
I know that currently NGSPICE is under development, so please consider my idea. To be able to build a virtual board on which to just load the hex file and observe will my device work, including the LCD and others is what we need.
I used Proteus in past (my university had the license), it use some kind of .dll files to this kind of models. The last updates (when I used) on MPLab (Microchip) allowed use the PIC simulator within the schematic. But only allow this in schematic environment (do not allow interact with the PCB).
I think its depends of -/issues/2119 and a full definition of how interact with this model files. For example, PSIM (a power electronic simulator) defines that the DLL linked to a symbol must have standard functions names called on: simulation start, simulation step and simulation end.
I am not a developer (just help with reports and tests) but this appear a long shot. It needs more than NGSpice and also more definitions on the symbols (to allow the users to interact in the Eeschema canvas).
In the past I played a bit around with the Proteus demo, and implementing the simulation capabilities into KiCad would be a real game changer. For example, you can simulate a PIC connected to a touchscreen (and a loudspeaker) running chess on it.
I tried this project, and it is really nice. I think this is the most comparable OSS solution to Proteus. It uses AVRSim and GPSim in the backend, with apparently some custom written circuit simulation.
Now to the bad things. This is the weirdest Open Source Software I have ever seen. The sources are GPL licensed, but only old ones are available from the website. At least, there is a precompiled AppImages of an old version available. Newer version need to be acquired via Patreon (where you need to pay). The SourceForge Repo seems to be outdated as well. So, It looks like as there is only one dev in the background. No wonder there is a fork on GitHub available:
Thanks for the suggestions! The good thing of Proteus is that you can see how the pins change and whether its what you expect. Its like an all pin osciloscope, also it gives the ability to test your circuit easily. A visual simulator is the future. I am trying with PicSimLab at the moment, which has good documentation. I can not work with GPSIM, its very hard to find out how to build my own circuits.
A simple example of something I did, I wanted to simulate a 3-way light switch with 12VDC toggle switches for a kitchen under-cabinet light system at a previous residence. I kind-of understood the concept, but simulating it in EveryCircuit really helped me understand the current flow with multiple switches.
Best visual simulation program I play with is falstads circuit simulator, howerver for things like simulation a full blown microcontroller you need a very accurate model of its internals, Or is it closer to you want to cheat, just having a way to say script a sequence on the output / input pins and simulate /log it.,
I knew a programmer that got a job on large industrial machines. His code had a problem so he started to step through the code to debug it, all the while charging a very large capacitor. Shock and awe ensued.
I am the opposite: EE with some software experience.
Beyond the educational propose, I think that @halachal want to say is that is not common to create a elaborate unit/system test script/enviroment for project with small CPUs. At least, it was not common in the companies that I worked (doing message displays, score borad for games, and other projects based on PIC/8051 plus few ICs: memory, logic and so on).
The Silicon Labs Integrated Development Environment (IDE) is a complete, stand-alone software program that includes a project manager, source editor, source-level debugger and other utilities. The IDE interfaces to third party development toolchains to provide system designers with a complete embedded software development environment. The IDE supports the entire 8-bit microcontroller (MCU) portfolio.
The Configuration Wizard 2 utility helps accelerate development by automatically generating initialization source code to configure and enable the on-chip resources needed by most design projects. In just a few steps, the wizard creates a complete startup code for a specific Silicon Labs MCU.
The Flash Programming Utilities allow you to download your code to a device and perform other memory operations without needing to use the Silicon Labs IDE. These utilities are static examples of the C8051Fxxx On-Chip Interface Utilities DLL detailed in application note AN117. The downloaded installation utility installs both the Windows Flash Programming Utility and the Command-line (32-bit) Flash Programming Utility.
The Silicon Labs ToolStick is an easy to use development system that allows designers to develop and debug application firmware directly on the target microcontroller using the Silicon Labs Integrated Development Environment (IDE). Once complete, designers can replace the Daughter Card with a Programming Adapter and program blank devices for use in their actual system.
Silicon Labs and Keil Software have teamed to provide support for the C8051F family of MCUs in the Keil Vision state-of-the-art development platforms. The Vision debug driver allows the Keil Vision IDE to communicate with Silicon Labs on-chip debug logic. In-system Flash memory programming integrated into the driver allows you to rapidly update target code. The Vision IDE can be used to start and stop program execution, set breakpoints, check variables, inspect and modify memory contents and single-step through programs running on your actual target hardware.
IAR Embedded Workbench for 8051 is a complete IDE with many smart features, including a highly optimizing compiler, a comprehensive debugger, integrated static analysis tools, and more. This workbench supports all EFM8 devices.

I am trying to simulate a display in my Keil debugger when running in the simulator, but I don't know how to add the display to the "Peripherals" menu. It says here that I should be able to change the peripheral settings, but it doesn't say how. Can anyone help me with this?
You can add such external peripherals with so called AGSI DLLs. This is described in application note 154 for 8051, 251 and 166 devices ( ) and it was described in application note 196 for all Arm based microcontroller. The latter one has been withdrawn because it was outdated. If you are interested, please send me a private message and I will send it to you. These AGSI DLLs only work with our simulator for ARM7/9 and Cortex-M0/M3/M4. They do not work for 'Fast Models', 'Fixed Virtual Platform' or 'Arm Virtual Hardware'. Since we stopped to implement simulation for on-chip peripherals at least 10 years ago, there is very limited use of AGSI DLLs.
Questions to you:
I am using a Texas Instruments TM4C123G Launchpad microcontroller, and I got the simulations in the screenshot from my university. I don't know how they are added because I was given an executable that set them up for me. How can I send you a private message? I am new to the community.
It seems that someone in your university has written one or more AGSI DLLs for Vision which simulates some of the on-chip peripherals and also an external display. Please ask them to how they have made it and maybe you get the source code from them so that you could modify it for the display you want to use. In that case, you would not have to start from scratch to write such an AGSI DLL.
Suppose the MCU simulation software is reliable and easy to use. In that case, one can also learn the MCU platform using MCU simulation software while the actual hardware is unavailable or you are waiting for it to arrive.
Sometimes, you want to quickly simulate your op-amp circuit, power supply circuit, or some analogue portion of the project by doing simulations and not wanting to do hardware design and wait for the proto boards to arrive to start the testing.
