Then, you need to look at the datasheet of the LCD with the AY0438 in it. Look at figure 4 of the AY0438 datasheet. This figure shows you how to control the 32 segments. If I remember correctly, you have to connect the LCD(Phi) to the clocking signal for it to work. How many digits does the LCD have?
