interfacing keypad to psoc1
I' ve been trying to write the code for a 8 by 7 keypad using polling method . The problem is that I have all the coloumns connected to 4.7K external pull up resistors. And I cant able to find out which drive mode to be set for both cols. & rows. I have tried every possible combination. Pls suggest which should be used and also pls verify my code. The project is attached below.
