Hello Leigh
I think we connect extra key as you adviced.
When it is in key scanning mode pressing any key it will show
key value.There is one more idea can we program for pressing
key number 1 and 2 together to go to the mode for displaying
1000 and should be able to decrease and increase by pressing
0 and 1.What is your opinion.If you have better idea please tell
me.
Regards
George
