Controlling a LCD Display with a digital pot
Posted: Wed Aug 29, 2012 10:47 pm
I have used in one of my projects the above display and digital pot so that the user can adjust the screen contrast via push buttons.
The X9C103PZ is digitally controlled potentiometer. This device consists of a 99 resistor
Array, wiper switching network, a control section, and non-volatile memory. The wiper position is controlled by the CS, U/D, and INC inputs. The position of the wiper is stored in nonvolatile memory and then is recalled upon a power-up operation.
I have used 2 EB016-002 1 is for the LCD Display due to it’s size and the other is for the digital pot and pull up resistors
I hope this is of some use and happy experimenting
