The INPUTHEX routine can be used when you have a RS-232 interface on your uP.

The RS-232 interface can be connected to a serial communication port of your computer.

<span style="font-family: Arial;"> </span>

This way you can use a terminal emulator and the keyboard as input device.

You can also use the build in terminal emulator.

The input entered may be in lower or upper case (0-9 and A-F)

<span style="font-family: Arial;"> </span>

If var is a byte then the input can be maximum 2 characters long.

If var is an integer/word then the input can be maximum 4 characters long.

If var is a long then the input can be maximum 8 characters long.

<span style="font-family: Arial;"> </span>

In VB you can specify <span style="font-weight: bold;">&H</span> with INPUT so VB will recognize that a hexadecimal string is being used.

BASCOM implements a new statement: INPUTHEX. This is only to save code as otherwise also code would be needed for decimal conversion.
