Hi,
I have interfaced a 4x4 basic keypad and we have programmed the keypad. However we are facing the following problems:
1> we do not know how to incorporate the key being pressed or not within a stipulated amount of time. We do have a "delay" include file but do not know how to modify it as per the requirement.
2> we are unable to shift the cursor on the lcd screen while pressing the next key.
e.g. if we press abc(key2) and press def(key3) the letters are overwritten on the initial cursor position.
If you all have any idea about the above mentioned could you please mail us at saraf.pranav@gmail.com. We can mail you the present code too.
