+# k400p-fn-lock-for-windows
+ Lock Fn keys on K400+ (for windows)
+
+## Goal
+This program locks the fn key for the Logitech K400+ bluetooth keyboard on Windows. 
+Having the F1-F12 without pressing the Fn key is nice for developers.
+
+I wanted a simple way to do the same as the Logitech Options/Options+ softwares WITHOUT their continuously running processes.
+
+## Download
+Precompiled binaries available here :
+https://github.com/dheygere/k400p-fn-lock-for-windows/releases/tag/v1.0.0
+
+## How to use
+Running `k400p-fn-lock.exe` will lock Fn key till next reboot. 
+Revert with `k400p-fn-unlocklock.exe` to unlock and restore media keys.
+
+## How to build
+
+- build with gcc: 
+ `gcc main.c -o dist/k400p-fn-lock.exe -I hidapi/include -L hidapi/x86 -lhidapi` 
+ `gcc main.c -D setMediaKeys -o dist/k400p-fn-unlock.exe -I hidapi/include -L hidapi/x86 -lhidapi`
+- build with msvc:
+ `build.bat`
+
