#88424 - Delay are not suppose to get rid Responding to: ???'s previous message |
The Keypad will debounce.
So Delay can make the prompt appear slower so that the debouncing won't affect the keypad. The problem now is, for column 3, that is key 3,6,9,# for this 4X4 matrix keypad can't press at all. others 12 button is ok. From my program, there is no problem which allow column 3 behave in that way. So I think is hardware problem. Thanks Jan. |
