Richard,

I'm not always entering 5 digits. The range must be between 0 and 25000 and then convert it to a hex value. The code for scanning the keypad and store the separate values that isn't a problem for me. Do you have an example of de code for me to do the conversion from the single digits to a combined value? I tried to do it by myself but has some problems to multiply the digits. Especialy for the higher digits. (multiply bij 100, 1000, 10000)

Regards,

Peter
