SERIAL READ

This command allows you to read one or more bytes, up to a whole string, from the serial port. The simplest syntax is the one that allows you to retrieve a string from the serial port, indicating the number of characters (chars) to read. It is possible to omit the size (in bytes) to read and instead directly indicate the type. In this case, a piece of data will be read from the serial port as long as the indicated type. In this last use case, the programmer must pay particular attention to the order of the bytes, where the data exceeds the size of one byte. In other words, the data is read with the endianess prevailing on the target computer. To change this behavior and ensure that the endianess is the same, regardless of the computer used, it is necessary to use the BIG ENDIAN or LITTLE ENDIAN option, to indicate the preferred endianess.

EXAMPLE

 result = SERIAL READ AS BYTE
