#136141 - what keypad ur using.as 4x4 Responding to: ???'s previous message |
IF you need the best results try from the Forums, This thread has some implementation ideas: http://www.8052.com/forum/read.phtml?id=50084 If you are using the 4x3 keyboard like a ordinary Telephone. you can also use one DTMF Decoder chip and there you can easily get the values of digits which you are pressing. Confirm it , what is your real requirement. I hope it will be better to use DTMF decoder if you need to get number of digits rather than the keyboard. Thanks, MaheshK |
