Simulating Embedded Development To Reduce Iteration Time
![<div><img alt="" class="attachment-large size-large wp-post-image" height="450" src="https://hackaday.com/wp-content/uploads/2025/03/Arduino-GIF-example-in-my-CYD-simulator-0-1-screenshot.png?w=800" style="margin: 0 auto; margin-bottom: 15px;" width="800" /></div><p>There’s something that kills coding speed—iteration time. If you can smash a function key and run your code, then watch it break, tweak, and smash it again—you’re working fast. But if you have to first compile your code, then plug your hardware in, burn it to the board, and so on… you’re wasting a lot of time. It’s that problem that inspired [Larry] to create <a href="https://bitbanksoftware.blogspot.com/2025/03/a-simulator-to-boost-embbeded-software.html" target="_blank">an embedded system simulator to speed development time for simple projects.</a></p>
<p>The simulator is intended for emulating Arduino builds on iPhone and Mac hardware. For example, [Larry] shows off a demo on an old iPhone, which is simulating an ESP32 playing a GIF on a small LCD display. The build isn’t intended for timing-delicate stuff, nor anything involving advanced low-level peripherals or sleep routines and the like. For that, you’re better off with real hardware. But if you’re working on something like a user interface for a small embedded display, or just making minor tweaks to some code… you can understand why the the simulator might be a much faster way to work.</p>

A #Quantum #Simulator is a specialized computer designed to model the behavior of quantum systems, which are governed by the principles of quantum mechanics.
These simulators help scientists understand complex quantum phenomena that are difficult or impossible to study with classical computers or experiments.
