INPUTHEX/de

= (**COPIED FROM ENGLISH PAGE**) === Action

Allows hexadecimal input from the keyboard during program execution.

 

 

Syntax

INPUTHEX [" prompt" ] , var[ , varn ]

 

 

Remarks

prompt	An optional string constant printed before the prompt character.
Var,varn	A numeric variable to accept the input value.

 

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.

 

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)

 

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.

 

In VB you can specify &H 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.
