It is based on Rs232 library for Windows/Linux created by Teunis van Beelen. Schematic for RS485 converter is provided. This library is divided in two parts 1 - C library compiled like shared library ( "so" or "dll" extension) 2 - C# and Python wrapper library that uses dinamic C library. For Windows ___________ C library is compiled with MinGW. Eclipse project is provided. Only is posted 64bit dll library, you can compile over 32bit for 32bit support. The demo project is a Visual Studio 2008 C# project and it has 2 classes : the Program class, where main method is, and Rs485 class that is a wrapper for the dll library. For Linux __________ C library is compiled with GCC. Netbeans project is provided. Only is posted 32bit shared library, you can compile over 64bit for 64bit support. The demo project is a Python project and it has 2 files : the program main.py and the class Rs485.py that is a wrapper for the shared library. Technical notes _______________ RS485 driver can be : SN75176 or ST485 RTS COM pin is used for TX/RX control on RS485 Bus. Diode D2 allows to the PC receive the transmited packet, that way the library ensures the packet is all transmited before change RST state.
