Open Source C# Raspberry Pi Software

Snap7, through three specialized components: Client and the inedited Server and Partner, allows you to definitively integrate your PC based systems into a PLC automation chain. Designed to transfer large amounts of hi-speed data in industrial facilities, it scales easily, down to small Linux Arm boards such as Raspberry PI. Hi level object oriented wrappers are provided, currently C/C++, .NET/Mono, Pascal, LabVIEW, Python with many source code examples. Very easy to use, a full working server example is not bigger than the “Hello world”. Many projects/makefiles are ready to run to easily rebuild Snap7 in any platform without the need of be a C++ guru. Very detailed documentation provided.

Turn Visual Studio into a powerful HMI/SCADA development package by simply dragging and dropping, no coding required. DF1, Ethernet/IP for Allen Bradley PLC controllers, and many more drivers. Free

This program was inspired by Mire De Collimation program written by Gilbert Grillot and Al's Collimation Aid. I combined best features of both and addes some of my own. Purpose of this program is not to reinvent the wheel, but rather to learn new technologies, become better at colimating my telescope and to learn something new. Main purpose of this program is to help you with aligning optical elements of your telescope such as secondary mirror, primary mirror, focuser, etc. Collimation Circles is developed with .NET 7 and AvaloniaUI Framework using MVVM architecture patern. Program was tested on Windows 10 and 11, Ununtu Linux 22.04.1 LTS (Wayland) and Raspberry PI OS Bullseye. I'm not able to test it on macOS, but it should work. Suggestions and contributions are welcome!
