Simple DIY STM32 Oscilloscope Project

A new project from BTTLab demonstrates how to build a simple, single-channel oscilloscope using the built-in analog-to-digital converter of an STM32F207 microcontroller. As Hackaday tells it, the device achieves a resolution of twelve bits at two million samples per second, making it suitable for basic low-frequency circuit debugging. The project's creator warns that users must implement front-end protections to avoid damaging the microcontroller with voltages outside its rated range.
