Protocol Analysis (I2C / SPI / UART)

Purpose

Guide agents through software-side serial bus analysis: logic analyzer workflow, sigrok/PulseView decoding, correlating captures with firmware drivers, and Python-based parsing — bridging skills/baremetal/spi-i2c-baremetal and hardware bring-up.

When to Use

• Sensor not responding — verify clock and data on bus
• Compare kernel driver transactions vs datasheet
• Document expected transaction format for CI/regression
• Teaching protocol layers without expensive lab gear (sim + decode)

Workflow

1. Capture stack
