Resolve CAN bit timing (BRP, tq, phase segments, SJW) and sample point from clock and bitrate, plus CAN-FD DLC payload mapping.

Compute CRC-32, CRC-16/ARC, CRC-16/MODBUS, CRC-16/CCITT-FALSE and several CRC-8 variants locally in your browser.

Parse DBC message and signal definitions in your browser, inspect bit layout, factor/offset, and decode physical values from a hex payload.

Convert UDS DTCs like P0420 to/from two-byte frames, build and parse ISO-TP single/first frames locally.

Compute Modbus RTU CRC-16 and ASCII LRC, build complete frames, and map 1-based references like 40001 to 0-based PDU addresses.

Decode Mode 01 41 <PID> <data bytes> responses into RPM, speed, coolant temperature, MAF, voltage and other common OBD-II values.

Convert cutting speed to spindle speed, feed per tooth to feed rate, plus metric tap drill size and theoretical surface roughness.

Paste G-code to resolve modal G0/G1/G2/G3 and G90/G91, preview the XY toolpath, and compute block counts, bounding box and path length.
