LCD JHD162A dtn

Hi, i am new in uC programming, i want to use the LCD to display a clock signal from my AT89C52 uC, i found the datashet for JHD162A dtn, but the tut, does not have the instructions used to set chars on LCD panel, I understand the most functions of pins, but, Can someone explain me, what is the use of the RS pin?, and, Can you give me an example to set a single char on the module?, that is everything, from there, I can make my own path to master the LCD module p ), was a joke!!!.

Thank you, from Mexico to the world.

the RS pin determines how the signal in the d0-d7 is interpreted by the lcd controller . if rs is high the data is interpreted as a command to the controller or otherwise data (or opposite ? ) ..hava a look at nigel lcd tut: for more info.

Many many, thank you!!!

Then thank you very much that they answered my post, already I found something very good in the page 8052.com

Pues muchas gracias a los que contestaron mi post, ya encontré algo muy bueno en la página 8052.com, thank you!!!

i have done LCD interfacing with parallel port and avr microcontroller. The above codes are the working ones

Ok

I already understand that code, tnks very much.
Just another question, where do you write that C code?
Which compiler or editor is used for program that?

I undestand C code now, but where can I found that SW?

-----------------------
Muy bien, ya entendí ese código, muchas gracias.
Solo otra pregunta, ¿En dónde escribes ese código de C?
¿Cuál compilador o editor es usado para programar eso?

Si entiendo el códigode C ahora, pero ¿dónde encuentro ese software?

******
Thank you very much, muchas gracias

You need a piece of software called a compiler. There is a freeware compiler called SDCC. Here's the link

http://sdcc.sourceforge.net/

Good Luck and de nada

Ok, thanks im already making the download, thanks bro!!!

Esta bien, gracias, ya estoy haciendo la descarga, gracias hermano!!!!

I used WinAVR for compiling the above programms. I have explained about it in my book. it is a FREE BOOK.
