ESP32 Bit Pirate protocol workbench with wired buses, signal capture and browser tools

Wired buses

Start here for board bring-up, memory dumps, sensors, serial consoles and GPIO-level bench work.

I2CI2C debuggingScan unknown buses, identify addresses, read registers and recover stuck SDA/SCL lines.scan · read · dump · recover SPISPI debuggingProbe SPI devices, validate wiring, read JEDEC IDs and move into flash or EEPROM workflows.probe · read · write · flash UARTUART and HDUARTInspect serial consoles, bridge traffic, detect baud rates and work with half-duplex links.bridge · sniff · autobaud · console 1-Wire1-Wire debuggingRead device IDs, test DS18B20-style sensors and inspect timing on simple one-wire buses.read · identify · timing 2-Wire2-Wire smartcardWork with SLE4442-style smartcards through the matching 2WIRE mode and shell.ATR · read · security 3-Wire3-Wire Microwire EEPROMRead, write and erase 93Cxx EEPROM devices after confirming pinout and organization.dump · write · erase I2SI2S audioTest microphones, speakers, clocks and sample paths when audio hardware needs quick validation.tone · record · clock DIO/GPIOGPIO, DIO, PWM and servoCheck logic levels, pulse pins, measure frequency and exercise simple digital outputs.pulse · measure · PWM · servo

Debug and adapter protocols

Use these pages when ESP32 Bit Pirate acts as a debug probe, USB bridge, signal capture tool or browser-controlled GPIO interface.

Wireless and RF

These protocol pages help with radio modules, remote-control captures, local wireless checks and repeatable RF bench workflows.

Peripheral and field protocols

Use these when the target is a module, network peripheral, modem or field bus rather than a simple board-level signal.

From protocol pages to practical workflows

Protocol pages explain the role of each mode. Recipes, tools, flashing and hardware pages turn that context into a concrete bench action.
