CULFirmware | Firmware for the CUL transciever to work

CULFirmware is a C library typically used in Internet of Things (IoT), Arduino applications. CULFirmware has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

This is the NetHome firmware for the CUL-stick (see and The NetHomeCUL firmware builds heavily on the work made by Rudolf Koenig for the FHEM-project (see in fact large parts of this file is a direct copy of Rudolf’s readme. The difference between the firmwares is that Rudolf’s version implements a number of specific protocols. The NetHomeCUL does not implement any protocols, it just sends and receives raw pulse data and let PC-software do the encoding/decoding. The actual firmware is located in the file: NetHomeCUL.hex. Instructions on how to install the firmware on the CUL stick can be found on: Thanks to the MyUSB project () the device/firmware combination confirms to the Universal Serial Bus Communication Device Class Abstract Control Model (USB CDC ACM) specification, so it can be used out of the box with a lot of operating systems. We incorporated the relevant parts of MyUSB, version 1.5.2.
