Article Summaries:

  • The ESP32‑Bus Pirate firmware has been updated to turn low‑cost ESP32‑S3 boards into a versatile, affordable debugging platform. Building on the Classic Bus Pirate’s multi‑protocol support (I²C, SPI, UART, 1‑Wire), the new release adds advanced signal‑inspection features, including a “Wizard” pin activity analyzer that detects PWM, data bursts, and noise, giving basic logic‑analysis capability. A profile system now lets users save and reload full pin configurations, while the CLI gains auto‑completion and improved command handling. Internal storage expands to ~4.5 MB for logging. UART support now auto‑detects pins, performs autobaud analysis, and emulates devices such as GPS modules. The firmware supports several ESP32‑S3 boards and plans for FM radio, cellular, and 5 GHz Wi‑Fi integration.
