Qt5/C++ application for automated label printing on DYMO LabelWriter printers with integrated DYMO scale support. Create custom SVG-based templates, manage prices, and print product labels with automatic weight calculation.

A C++ class that uses libusb to interface with MCP2210 devices. It can be used to control the several aspects, such as NVRAM or volatile configurations, GPIO directions and states, or to perform SPI transfers. Note that this is a class variant made specifically for Qt. If you wish to use the original, non-Qt variant, please refer to https://gitlab.com/bloguetronica/mcp2210.

A C++ class that uses libusb to interface with CP2130 devices. It can be used to configure the OTP ROM of such devices, as well as to control them. The class was made for Qt. If you wish to use a derived non-Qt version, please refer to https://gitlab.com/bloguetronica/cp2130.

A C++ class that uses libusb to interface with CP2130 devices. It can be used to configure the OTP ROM of such devices, as well as to control them. This class was originally derived from the corresponding class for Qt. Please refer to https://gitlab.com/bloguetronica/cp2130-qt if you wish to use the original class instead.
