![]() ![]() In short, these functions will help you to prepare the data you wish to send. These functions are important tool for data manipulation, since serial communication requires correct data flow in a sense of sending/reading structured data to/from designated addresses of external devices. Since serial communication is associated with relatively large amount of data transfer and to make manipulation of this data easier, there is a special group of functions with a prefix buffer. ![]() TNG already provides all required commands that implement serial specification so that you can just relax and read/send the data on command so to speak. While serial communication comes with its own rules, requirements and data framing, you would not need to worry for any of that. PlanetCNC motion controllers also support hardware UART serial interface, but this will not be a subject of this tutorial, at least not in this part. PlanetCNC TNG software possesses all the tools for serial communication with external equipment. ![]() The final goal would be a successful control of external MODBUS input/output board, but, to achieve this, we need to start with the basics. This series of tutorials will try to explain and demonstrate how to use PlanetCNC TNG software for the means of serial communication. ![]()
