Debugging Electronics for the Software Engineer
summary
Checklist for first bringup: use a multimeter diode mode to probe pins against Vcc/GND and expect ~0.3–0.7 V on clamp diodes to spot bad solder joints; power the board from a bench power supply with current limit and measure every rail with two multimeters and an oscilloscope to catch voltage droops or spikes; correlate timing with a logic analyzer (Sigrok/OpenBench or Total Phase USB analyzer) and an oscilloscope (aim for ~5–10× analog bandwidth and ~1 GS/s sampling) to find swapped bytes, race conditions, or missed interrupts.
