espp Web Apps
14 self-contained browser tools hosted with the espp documentation. They use the Web Serial / WebUSB / WebHID APIs (Chromium-based browsers) and talk directly to your hardware — nothing to install.
Basicmicro MCP Console
Test and configure Basicmicro MCP/RoboClaw motor controllers over a USB-UART (packet serial) or USB-CAN (slcan + CANopen/DS402) adapter: device info, motion control, encoders, and an SDO object browser.
CAN Bus Console (slcan)
Generic CAN bus console for slcan (LAWICEL) USB-CAN adapters over Web Serial: send standard/extended/RTR frames, periodic transmits, live per-ID monitoring, and log export.
espp BLDC Haptics Console (WebUSB)
Control and visualize an espp BLDC haptic knob over WebUSB: live dial, detent presets, and control commands. Firmware update and crash inspection are separate modules (see the ota / coredump consoles via the device hub).
espp Board Console & ESP Flasher
General-purpose Web Serial board console and ESP flasher (esptool-js): serial monitor, reset/bootloader controls, and firmware flashing.
espp CAN Bridge Console (WebUSB / Web Serial)
Drive a USB-to-CAN bridge device over WebUSB or Web Serial: configure the bus, send CAN frames, and watch a live monitor of received traffic using the espp stream_frame protocol.
espp Core Dump Console (WebUSB / Web Serial)
Inspect ESP-IDF flash core dumps in the browser: crash summary, ELF core dump download, client-side nearest-symbol backtrace resolution and erase, over WebUSB or Web Serial via the espp coredump component.
espp Device Hub (WebUSB / Web Serial)
Connect to an espp device over USB (WebUSB / Web Serial) and discover which modules it runs. The device answers a capability query on the reserved dispatcher discovery module (0xFF) with its name, firmware, and the list of modules — each shown as a tab that links to its hosted web app.
espp DS402 Drive Panel (WebUSB / Web Serial)
Commission a CANopen CiA 402 (DS402) drive over a USB-to-CAN bridge from the browser: SDO object read/write, the DS402 state machine, mode selection, target/actual values, and a generic object-dictionary panel for vendor-specific addresses.
espp MCP266 Console (WebUSB / Web Serial)
Configure, command, and monitor a Basicmicro MCP266 dual-channel motor controller from the browser over USB (WebUSB / Web Serial): per-axis position loop setup, profile-position moves, and live status. The device runs the CANopen driver and exposes a high-level protocol.
espp OTA Console (WebUSB)
Update espp device firmware over WebUSB: streams a .bin to the espp ota component
ODrive ASCII Web Serial Console
Web Serial console for the ODrive ASCII protocol: interactive terminal, quick motor controls, and live position/velocity plotting.
ODrive ASCII WebUSB Console
WebUSB console speaking the ODrive ASCII protocol over the vendor bulk interface (no serial driver needed).
ODrive Native WebUSB Control Panel
