There are a whole slew of Arduino simulators out there, many free, and some paid products as well.
The CodeBlocks Arduino development environment includes a free Arduino simulator, still under development but functional.
Simuino simulates the Arduino Uno and Mega pins - not a pretty-looking realistic simulator, but it works.
The Python based Arduino ...
I like to use circuits.io aka TinkerCAD for this.
It's cloud based and has some nice features including PCB design and collaboration.
IMO the Arduino simulation and capability is impressive and intuitive.
Plenty of options exist in the world of electronics simulators, but circuits.io aka TinkerCAD is probably the most versatile one out there.
You can compose your circuit on a virtual breadboard which looks just like real.
You can actually watch a LED blinking or press a button during real-time simulation rather than struggling with abstract waveforms.
Be aware that no simulator will reproduce real-life situations. There have been plenty of posts on the Arduino forum about problems with code or electronics, which turn out to be something subtle, such as:
Race conditions (related/dependent events not always happening in the same order)
Voltage levels, eg. floating input pins
Driving motors ...
Yes, you can, try using Proteus ISIS for simulating your code...
For full emulation of Arduino, there is a shareware program called VBB (Virtual BreadBoard), I tried it too and it was nice.
Edit: You can check my detailed tutorial here on how to simulate on Proteus ISIS
I believe this website has a list of both emulators and simulators along with their price and availability.
Since some users mentioned there are broken links in that website, here's a selection of emulators I found. Note that some descriptions may have been taken from the mentioned link:
Emulino: Is an open source linux based software in early ...
I am working with the new Wokwi Arduino Simulator. Wokwi Arduino simulator is based on AVR8js engine which is made open-source. You can find the link here
Following are the main features of the simulator
• Supports multiple file projects
• Supports the Arduino libraries
• Whatever compiles on the Arduino IDE will compile on the simulator
Virtualbreadboard has a new VBB4Arduino 'Two Arduino's' edition which includes BOTH a JVM Arduino emulator AND a AVR Instruction set simulator with examples that cover almost all of the Arduino distribution examples and a bunch of peripheral hardware - LCD's, WS2812 Neo LEDS, Motors, Servo's, Logic Analyser and more.
The Arduino Uno uses the Atmel Atmega328p microcontroller, which only has one debug option, DebugWire. There are a few tools that can work with it, but the least expensive and most commonly available is the AVR Dragon.
You can use AVR Studio 6 for this. You can use the .elf file file produced during the Arduino build process directly, but setting up the ...
The answer is "yes, you can use extra AVR Flash memory as non-volatile EEPROM-like Flash memory storage, very similar to an STM32 microcontroller."
One of these days I'm going to write an Arduino library to make this really easy for the beginner. For now, however, I'm going to simply post links to valuable references that contain the full answers and that I ...
Yes you can. This Arduino IDE add on lets you make calls to code store in the bootload of memory so you can make changes to the flash memory.
The number of times you rewrite a cell are limited.
I'd suggest you are better off with adding a FRAM memory chip.
Get a 5V part with SPI interface. Fast reads,...
You could e.g. use my simulator.
It is especially suitable for PLC-like applications, where multitasking is achieved by cyclic evaluation of interconnected circuit-like objects: Timers, Markers, Latches, Oneshots and Registers.
You can use it to simulate your controlled system as well, as becomes clear from the examples in the download. It has modest ...
a way I can write my code and emulate/test it using a desktop computer
If you mean being able to "unit test" using a desktop computer, I can offer a library I wrote called arduino_ci.
It doesn't offer emulation. You would express your tests in code. For example, here is a test pulled from the reference documentation that validates the data written to a ...
I made this video and github just for this about a year ago.
And here is the code:
2-axis joystick connected to an Arduino Micro
to output 4 pins, up, down, left & right
If you are using pull down resistors, change all the HIGHs to LOWs and LOWs to HIGH.
This skectch is using pull up resistors.
int UD = 0;
int LR = 0;
/* Arduino Micro output ...
I am using the Wokwi Arduino simulator for a long time. It runs on all three platforms. Mobile, Windows OS, and macOS.
I have checked the working of the simulator in both Android and iPhone. Both give a good performance as well.
I have successfully reprogrammed the UNO's R3 8U2 to support keyboard emulation, as to just this. Making dedicated user inputs for kiosks to Computers. I recommend NicoHood's GitHub as it allows simultaneous Arduino Bootloader and Keyboard functionality, making it easy to reprogram the Arduino.
This along with using Capacitive Touch Sensor connected to ...
You could use the Simulator in Atmel Studio or something like Virtual Breadboard which looks good
The Atmel Studio simulator might take a bit of work to simulate your devices but if you have 2 months then maybe that's okay :) If you want to use the simulator in Atmel Studio then you might also find the Arduino plugin for Atmel Studio useful.
I think there ...
If you want to run the Arduino sketch on your desktop, you just have to
implement the Arduino core library for your PC.
It may not be as bad as it sounds. If your program makes only minimal
use of the Arduino core, you may implement only the parts you really
need. For example, this partial implementation is enough to run your
Disclaimer: I have no affiliation with Wokwi (based on opensource AVR8js engine) except that I have learnt a lot from it.
I just tried it on the free Wokwi Arduino simulator(my favourite Arduino simulator for learning) and it worked in a blink!
Here is what I did to load the hex file into the Arduino simulator
Go to the Arduino IDE and open the basic blink ...
Since an Arduino is "just" a microcontroller with some specific bootloader and commonly programmed via the Arduino IDE, you can also program it like any other microcontroller.
There are several projects offering USB functionality as a library, in the Arduino world or outside of it. Use your favorite web search engine to find them. With such a ...
There are many different processors used in making many different types of Arduino boards. So there is no one way to write Arduino machine code.
There are emulator for simpler processors available for the asking. But, while they work, it is not believe they claim to be totally accurate.
At one point in processor development history, ICE machines were ...
Take a look at section 30.8 in the datasheet:
It has all the information to reprogram the bootloader section of the flash during runtime.
The bootloader partition size can be adjusted as well.
Yes you can, and fairly easily. There is a wonderful online simulation (completely free) called TinkerCAD. It has an excellent breadboard simulation, with parts like transistors, LEDs, ICs, and Arduino. You can program the Arduino and run it all in a live simulation that includes interactive inputs (pushbuttons, DIP switches, etc.).
[Edit: The following ...
The easy answer is to use a Leonardo, Micro, or Due instead. They already support USB HID functionality via Mouse and Keyboard.
If you insist on using an Uno R3 then you will need to reprogram the on-board ATmega16U2 to accept serial commands from the ATmega328P and generate the appropriate USB HID events.
If you're using an Uno or clone that doesn't have ...
I have not done extensive testing with the simulator but here is what you do open code blocks start a new project. Then under the target choose simulator. See the picture for details.
I just tested it out for the simple program but this looks pretty cool.
This might not be right for you, but the Visual Micro plugin for Atmel Studio and Visual Studio has a USB debugger which only uses Arduino code.
In the background the debugger uses Serial which might affect some time-sensitive applications.
