Hi all, I am new to this controller,I want to interface the 7 segment LED(common anode) with P89LPC932,i have to display 0 to 999 on display.I am using 3 seven segment LED displays.Are their any sample programe for this? Thanks n regards kanaka

To Reinhard: 1) are you sure Kanaka understands German 2) I found no LED 'example' To Kanaka: Everybody and his brother is going to come out of the woodwork with multiplexed solutions. If your LEDs are less than 20mA per segment a string of 3 shift registers provide a simpler and cheaper solution. Erik
There is an example with the title: "SAA1064 4-digit LED-driver with I²C-bus interface" Well, he may not understand German, but still the program might help him to think about his own problem.
Hi, I am Miss bye the way. I do not understand German. But "Danke (dahn'-kuh);" for your concern.. I am already using a microcontroller for a different purpose and along with that i want to use 7segment LED Display - 3nos, so the document doesnt help me.. Thanks and regards, Ms. Kanaka
I want to interface the 7 segment LED(common anode) with P89LPC932 You are using a uC with hardware IIC. Philips have LED drivers that run off the IIC bus. Erik
"Philips have LED drivers that run off the IIC bus." http://www.philips.com/i2c And also several other manufacturers; eg, http://www.maxim-ic.com/Display.cfm
How is the question. By transistors? Logic chips? a display driver? Once you choose the method, the code will follow.
I must add one more decision to be made How is the question. By transistors? Logic chips? a display driver?, multiplexed or not Once you choose the method, the code will follow. one added bit: if your LED segements use less than, say, 20 mA, the multiplexing typically is the wrong choice (more complicated, more expensive).
