LongToHex

Syntax:

    stringvar = LongToHex(number)

Command Availability:

Available on all microcontrollers.

Explanation:

The LongToHex function converts a Long number into hexadecimal format. The input number should be a Long variable, or a fixed number between 0 and 4294967295 inclusive. After running the function, the string variable stringvar contains an 8-digit hexadecimal number.

Example:

    'Set chip model
    #chip 16F1936

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


    'Send EEPROM data over serial connection
    'Uses Hex to display as hexadecimal
    For CurrentLocation = 0 to 65535
        'Send location
        HSerPrint LongToHex(CurrentLocation)          ' <<< the LongToHex instruction
        HSerPrint ":"
        'Read Long and send
        EPRead CurrentLocation, CurrLong
        HSerPrint Hex(CurrLong)
        'Send carriage return/line feed
        HSerPrintCRLF
    Next

Key line: LongToHex(CurrentLocation) — formats the current address as a fixed 8-digit hex string, so addresses line up neatly in the terminal output regardless of their value.
