libgpiod3

C library for interacting with Linux GPIO device - shared libraries

libgpiod encapsulates the ioctl calls and data structures behind a straightforward API. This new character device interface guarantees all allocated resources are freed after closing the device file descriptor and adds several new features that are not present in the obsolete sysfs interface (like event polling, setting/reading multiple values at once or open-source and open-drain GPIOs).

voacapl

HF propagation prediction tool

voacapl is a program that uses empirical data to predict point-to-point path loss and coverage of a radio transceiver operating in the high-frequency (3 to 30 Mhz) range, if given as inputs data such as the transmitting and receiving antennas, solar weather, and time/date.

libnetcdf19t64

Interface for scientific data access to large binary data

NetCDF (network Common Data Form) is an interface for scientific data access and a freely-distributed software library that provides an implementation of the interface. The netCDF library also defines a machine-independent format for representing scientific data. Together, the interface, library, and format support the creation, access, and sharing of scientific data.
