String Manipulation

Syntax:

    stringvar = ByteToString(byte_variable)     'supports byte.

Command Availability:

Available on all microcontrollers

Explanation:

The ByteToString function will convert a number into a string. number can be any byte variable, or a fixed number constant between 0 and 255 inclusive.  For Word number use WordToString(), Long numbers use LongToString(), for Integer numbers use IntegerToString() and for Single numbers use SingleToString()

The string variable stringvar will contain the same number, represented as a string.  The length of the string returned is 5 characters.

This function is especially useful if a number needs to added to the end of a string, or if a custom data sending routine has been created but only supports the output of string variables.

These methods will not support conversion of hexadecimal number strings.

Example1:

    'Set chip model
    #chip 16F1936

    'Set up hardware serial connection
    #define USART_BAUD_RATE 9600
    #define USART_TX_BLOCKING

    Dim SensorReading as Byte

    'Take an A/D reading
    SensorReading = ReadAD(AN0)

    'Create a string variable
    Dim OutVar As String

    'Fill string with sensor reading
    OutVar = ByteToString(SensorReading)

    'Send
    HSerPrint OutVar
    HSerPrintCRLF

    When using the functions ByteToString() do not leave space between the function
    call and the left brace. You will get a compiler error that is
    meaningless.

    ' use this, note this is no space between the ByteToString() and the left brace!
    ByteToString(number_variable)
    ' do not use, note the space!
    ByteToString (number_variable)
