When working with machines you will often be required to encode and decode integer and float data, modbus is a good example.Įarly computers used 16 bits to represent an Integer and 32 bits for a floating point number. In the video below I cover the above and also show you how to use Buffers in node-red to read text data from a file.Įncoding and Decoding Integers and Floats These options reads the data into you script/flow without any interpretation i.e as raw data. The third and forth options are for when the file contains binary data or text data encoded in another format other than utf8 or ASCII. Note: See data encoding tutorial for more details If the data in the file isn’t text data or not encoded as utf8 then the single utf8 and 1 msg per line options won’t work as with these options the data is read in, and decoded using utf8 into characters. The first and second options are the most common as files normally contain text data.
