IR detector

[geckogrotto]

Due to all the help I have gotten here I have everything worked out. I decided to buy a lcd screen so I could output the results to it but I have no idea how to hook it up.

LCD Display 16 characters with 2 rows LCD its Hitachi HD44780 compatible LSI controller

It has 16 pins.
1 GND Ground
2 +5v Power
3 Vcont Contrast voltage
4 RS Select
5 R/W Read/Write
6 EN Enable
7 DB0 Data bus
8-14 .......
15 LED K Backlight cathode
16 LED A Backlight anode

Ok 1 and 2 are pretty simple
Im not sure what pins I would hook up to my 16F628A chip. just data bus?
going to do some searching around to see what I can find was just so excited had to post Any help would be appreciated.

Ok looks like mine is almost exactly like the olympic timer

So it looks like 7-10 should be data..?

Man I still have so much to learn

Thanks lol
Good old fashion case of RTFM!

I have one questions about it tho, pin 3 on the lcd connects to the middle of the 20K resistor? I don't understand that part.

also I don't have a 20K resistor should I use 18K , 22K , 18K and 2K in series, or wait till I can get a 20K?

Thanks

It's a 20K potentiometer or trimmer. It's there to adjust the LCD contrast. You can use lower value. 1-10K still work. You can also use two resistor to make a fix contrast. Wich value... ARRRGGH close to be impossible to tell, no lcd work the same way.

You can still use HPWM to make a software controlled LCD contrast... for now, just plug-it and display on it.
