Frequently Asked Questions
How does little-endian (@1+) vs big-endian (@0+) parsing work?
In Intel little-endian (@1+), bits are packed starting from the least significant byte upwards. In Motorola big-endian (@0+), bits start at the most significant byte and follow standard network byte order.
Is my proprietary automotive CAN log secure?
Yes. All parsing, mathematical scaling, and canvas telemetry graphs run client-side in browser JavaScript. No vehicle IDs or logs are transmitted over the web.
