Tools & Demos

Eight CRC algorithms in one tool — CRC-8, CRC-8/MAXIM, CRC-16/IBM, CCITT, MODBUS, XMODEM, CRC-32, and MPEG-2. All math runs in your browser.

Enter your MCU clock and target baud rate to get register divisor, actual baud achieved, and error percentage for both 16× and 8× oversampling modes.

Compute system gain, EIRP, maximum outdoor and indoor range, and received power at common distances — with presets for the most common wireless protocols.

Spin a colorful task wheel, edit activities locally, manage cooldown rules, and control categories without any login or backend.

Estimate battery life from sleep/active current, TX bursts, reporting frequency, and temperature effects.

Build OTA state machines, inject failures, simulate rollbacks, and detect unsafe designs.

Connect to brokers over WebSockets or local bridge mode, publish/subscribe quickly, and run replay-driven reliability checks.

A client-side IoT developer tool for decoding hex/base64/UTF-8/JSON payloads with endianness controls and structured field extraction.

Define bootloader, application, OTA slots, NVS, stack, and heap regions for any MCU. Get a proportional visual map, utilization bars, and instant overlap warnings — all in-browser.

Paste hex from a sniffer, HCI log, or Wireshark capture and instantly decode every AD record — Flags, UUIDs, Local Name, TX Power, Manufacturer Specific (iBeacon, Eddystone), and unknown types.

Convert data both ways with delimiter controls, flattening options, type coercion, and private in-browser processing.

A practical daily tracker designed for quick glucose logging, weekly visibility, and clinician-ready organization.
