ITS URGENT…..

[dinesh yadav]

    THE KEYPAD SHOWN HERE HAS 7 PINS WHICH CONNECT TO THE MICROCONTROLLER (PIN 33 TO 39)

     ALSO ALL THE INTERNAL RESISTORS IN  THE  KEYPAD  CONNECT TO THE VCC.

   I DONT UNDRSTAND HOW CAN I CONNECT THESE RESISTORS TO VCC IN THE ACTUAL CIRCUIT BECAUSE THE  KEYPAD HAS GOT  ONLY 7 PINS ( I AM  TALKING ABOUT THE  ACTUAL KEYPAD NOT THE ONE SHOWN IN THE FIGURE)

 

PLEASE HELP…………..

use SIP resistor of 10 ka to give a pullup

it is a package of parallel resistors having single inline package 9 pins use this to provide VCC on all pins form 33 to 40….

OR you can use port 2, then you will not need any pullup resistor on your Keypad

Hi Dinesh,

“I AM  TALKING ABOUT THE  ACTUAL KEYPAD NOT THE ONE SHOWN IN THE FIGURE“

 

What you meant by the actual keypad. Kindly make it more clear.
