HD44780 1602 compatible LCDS for sale

I have had these working great with the pi so I imported some so you don't have to.

I can give example code and wiring if needed.

I'm pretty new to electronics and I imagine not all LCDs are created equal. I was looking to buy a couple of these, but found some that look similar that are much cheaper - can you explain if the ones you're selling are better than the ones that cost less?

I have no idea. I can't vouch for LCDS I have not used. I have also had more expensive LCDS than mine and they were of lower build quality. As long as they are HD44780 compatible they will work. A lot of the cheaper ones I found are delivery from china so long waits. My first china one took 3 weeks.

I'm watching and waiting xD

Anybody know where i can get one of these from in the UK without having an Ebay account?

I have a few left what means of payment do you have?

Could you share your sample code please ?

I have written a C++ library called PILib that implements an interface for HD44780 based LCD displays for the Raspberry PI. It can be downloaded at http://www.ctheroux.com/raspberry-pi/. It is pretty easy to use. Source code and complete documentation are included. A "Hello World" is as easy as:

Code: Select all

#include "HD44780.h"

int main() {

   CTTPI::HD44780 module(1, 16);
           // EN  RS RW  D4  D5  D6  D7
   module.initialize(17, 18, 0, 21, 23, 24, 25);
   module.writeString("Hello world!");
   return 0;
}

You can get these displays cheaper ... but you'll have to wait for them to arrive from China.

I've got a 16x2 and 20x4 LCD module and they are well worth a fiver given the fun you can have. If you want to save £2 then order from China or Hong Kong and wait 2 weeks

The modules are all pretty much the same. The only real differences are colour of the back light.

Details of my 16x2 and 20x4 LCD experiments in Python are on my blog.
