Hi Bill,

I'd love to see a video about using the Arduino IDE with STC8H microcontrollers.

These are modern 8051 chips that cost under $1, but they're surprisingly capable — 64KB flash, 8KB RAM, built-in USB, 4 UARTs, 12-bit ADC, SPI, I2C, PWM, and they run at up to 45MHz. No external programmer needed — you just plug in a USB cable and hit upload, same as an Arduino Uno.

There's an open-source Arduino Core that makes these chips fully Arduino-compatible. You write standard Arduino code — digitalWrite, analogRead, Serial.print, Wire, SPI — and it just works. Most Arduino libraries are compatible too, so you're not starting from scratch.

It even has a FreeRTOS port, so you can run multiple tasks on a chip that costs less than a cup of coffee.

The whole project is open-source: https://github.com/thevien257/STC_Arduino_Core

I think the community would find it interesting — a legit Arduino-compatible board for under a dollar, no programmer, no adapters, just USB and go.

Thanks!
