-
ESP-IDF JTAGA general-purpose JTAG programmer on an ESP32.
An ESP-IDF v6.0 component that turns any ESP32 into a standalone JTAG programmer with a browser UI — scan chains, program FPGAs, flash XMOS xCORE, play SVF files. Two backends: GPIO bit-bang on any ESP32 (1–5 MHz) or PARLIO + DMA on the ESP32-P4 (up to 40 MHz).
-
AD732x ADC DriverDMA-backed SPI driver for the 500 kSPS true-bipolar AD732x ADC.
An ESP-IDF component for the Analog Devices AD732x — a 500 kSPS, 8-channel, software-selectable true-bipolar 12-bit + sign SAR ADC. DMA-backed SPI transfers so the CPU stays out of the sample stream.
-
AudioBus64-channel audio + I/O multiplexing over a single twisted pair.
An ESP-IDF component that carries up to 64 channels of 32-bit audio, plus SPI/I2C/GPIO/MIDI tunneling, over a single Cat5 pair using commodity LVDS transceivers. Daisy-chainable, hot-pluggable, deterministic and zero-jitter.
-
Self-tuning Si5351Self-calibrating multi-output clock generator.
Si5351A driver and web control surface for the ESP32-P4-Nano, with hardware frequency counting on the PCNT peripheral, three-phase auto-calibration to ~1 ppm, and a background PI controller that compensates crystal thermal drift over hours.
-
RomEMUSPI flash & I2C EEPROM emulator with a real-time web UI.
Turns an ESP32-S3 or ESP32-P4 into a drop-in replacement for common SPI flash and I2C EEPROM chips. Upload images over WiFi or Ethernet, switch slots instantly, and the target boots from PSRAM — no chip flashing required.
-
PARLIO Audio TXI2S, TDM, ADAT and S/PDIF — all from one peripheral.
An ESP32-P4 audio transmitter that creatively repurposes the parallel-IO peripheral as a deep multi-protocol digital audio output. APLL drives the I2S MCLK, the same GPIO is fed back into PARLIO as an external clock, and DMA buffers shift out pre-encoded bit patterns on 16 parallel data lines — synthesizing I2S, TDM-8/16, ADAT and S/PDIF in software.
-
ADAT for ESP32-P48-channel ADAT lightpipe TX/RX in software.
ADAT optical I/O on the ESP32-P4: I2S+APLL generates the exact bit clock for transmit, while the RMT peripheral measures pulse durations from a TOSLINK module to recover the receive clock — no external PLL needed.
-
USB/IP for ESP32-P4Standalone USB/IP server for the ESP32-P4-Nano.
Plug USB devices into an ESP32-P4 (directly or via a hub) and expose them as native USB devices on remote Linux, Windows or macOS hosts — wire-compatible with the standard usbip and usbip-win2 clients.
-
AES67 for ESP32-P4Sub-millisecond AES67 / RAVENNA on a $20 board.
An ESP-IDF component implementing AES67 and RAVENNA-compatible audio-over-IP on the ESP32-P4, with PTP slave/grandmaster, ISR-driven DMA playback and a Layer-2 RTP hook that bypasses lwIP entirely.
