probe-rs: Making Embedded Development Feel Like Userspace Programming

If you've ever developed embedded firmware, you know the pain: cryptic flashing tools, primitive debugging methods, and a workflow that feels decades behind modern software development. You write code, compile it, flash it to hardware through a complex toolchain, and then… hope it works. When it doesn't, you're stuck with blinking LEDs and printf debugging over UART. probe-rs fundamentally changes…
