Online barcode decoder from the ZXing project.
rtl_433 is a generic data receiver, mainly for the 433.92 MHz, 868 MHz (SRD), 315 MHz, 345 MHz, and 915 MHz ISM bands. rtl_433 is written in portable C (C99 standard) and known to compile on Linux (also embedded), MacOS, and Windows systems. Older compilers and toolchains are supported as a key-goal. Low resource consumption and very few dependencies allow rtl_433 to run on embedded hardware like (repurposed) routers. Systems with 32-bit i686 and 64-bit x86-64 as well as (embedded) ARM, like the Raspberry Pi and PlutoSDR are well supported.
