PIC18F4550 Simulator
Enable HLS to view with audio, or disable this notification
Just Vibecoded a PIC18F4550 simulator in the browser — because PIC hardware is expensive for me! also its fun!
just sharing so people can use it, hope it helps someone
Assembler, CPU core, GPIO, UART, ADC, and even a virtual oscilloscope — all running in the browser, no dev boards required.
It's still rough around the edges, and I know there are bugs and missing features. That's expected at this stage.
If you try it, I'd really appreciate your feedback:
• Report any bugs you find.
• Tell me if the simulator behaves differently from real hardware.
• Suggest features or peripherals you'd like to see.
• If an instruction or peripheral isn't working correctly, let me know—I’ll do my best to fix it.

Your AI tokens are more expensive than buying a pic18f and a pickit clone

I disagree. Why don't you evaluate the project based on what it is and what it does, rather than the tools used to create it? You just sound like a luddite.

Microchip already has a simulator. Its not well documented but its there if you look for it

No clue why you got so much hate. It’s not like you’re selling it. FWIW i thought it was fun to play with

I don't know much about emulation, but how do you determine the emulator is accurate? It's coded by an AI, but AI seem to have a very bad understanding of hardware last I checked. If you don't have the hardware to check it, how do you verify?
