OpenScope-2C53T

OpenScope 2C53T is an open-source firmware developed as a replacement for the FNIRSI 2C53T handheld oscilloscope, multimeter, and signal generator, addressing limitations and bugs in the stock firmware through a clean-room rewrite. Its primary use case includes providing a customizable interface and various diagnostic tools for signal analysis, although it currently lacks live oscilloscope functionality due to unresolved FPGA configuration issues. Notable features include a four-mode UI, variable bitmap fonts, a robust battery management system, and various analysis algorithms, while emphasis is placed on ongoing development for reliable live data capture.
