this is the data sheet for the driver chip that is on the same printed circuit as the lcd
I was wondering how I need to get started.. i am still noobie at arduino.
all I want to use is the 5x 7 segment displays built into the lcd that used to show the clock.
and I am planning on building my own arduino clock.
the lcd screen info is p/n tvfd150ft007

can I just start probing (1.5v?) the lcd for the 7 segment lcds that I want
or should I start working on how to interface the driver chip with arduino?
if it is too big of a hassle, I will just go to radioshack a buy 4x 7 segment displays and matrix them
Does the display also have buttons on it as datasheet shows ability to interface 16x buttons to the chip?
You will need 3 pins to transmit data to the display chip STB, DIN & CLK and a forth DOUT if your reading the keys attached to the display. It looks like SPI_MODE0 so using the SPI library will take a lot of the grunt work out of programming. Most everything else you need will be in the datasheet but it may be a lot of trial and error to determine how the display is wired up. First thing is to determine what type of display the chip is connected to...
