fpSup

Firmware research and on-camera tools for the SIGMA fp. Everything here runs from AutoRun.txt on the SD card, in RAM only — remove the file, power-cycle, and the camera is stock. Nothing is written to flash. Firmware Ver.5.02 only.

Releases

productversionwhat it does
fpsup-gyrov1.11b writes Gyroflow's .gcsv and .json while recording
fpsup-og3kv0.1.1test 3:2 open gate, 3024×2010, eight frame rates — sensor modes 98/117, a native 2×2-binned readout rather than 6K resampled down. Records correctly at every ISO: v0.1.1test fixes the conversion-gain misclassification that cost 2.7 stops of highlight headroom above ISO 640.
fpsup-usbshellv3.1.0 the shell that answers shl over USB

Each release is two files. Copy AutoRun.txt and VSHL.BIN to the root of the card — no folder to make, no step afterwards. To combine two of them, use the card composer rather than copying both.

Explainers
