Here is one of the modified form of a project discussed earlier on this forum only
In above code :
The whole system is a kind of basic counter type system.
The observing area includes case '#': & case 'C': in the code
Here I use to enter a value up to 1 or 2 or 3 digits which gets printed on location (1,1) on LCD (as the dialed value)
and
After pressing key '#'
I get the same entered or dialed value result on the location (11,1)
Here the term Export(a++) is responsible for the complete function
A variable 'count' is defined as we can see in code before setup part . .
I use to make increments of count simply using key 'C' in case 'C': area
Now here comes the actual target :
I just want to equate the value of count with the 'Export[a]' value observed at (11,1)
Reason behind doing this is here :
I want to enter a random dialed single or double or triple digit number and want to start a count from that random dialed number in increasing order
For example =>
Say :
Enter a number '121'
and Enter (#) to display (11,1)
Then By pressing C it will count after '121' like :
122
123
124
125
126
and so on an on . . . . . Like that !!!!
or
Simply =>
Dial '11'
Enter (#)
Display(11,1)
Increment (C)
Result : 12 , 13 , 14 , 15 , so on . . .
Yeah I tried in Case '#' : but that is a complete disaster
Please Help Me getting the target !!!!!!!
Thanks
