Hi everyone,

Im using STM32F103VCT6 , and i want to play with the LCD and i dont know how to start!

if you can please send me some example code to write something on it 

the LCD is 16*2 with 8 data bits (GPIO from CPU) ...

and if you have some sites to learn how to start it will be greate .

[I have some knowlage in C , but not with those CPUs]

thanks a lot

Try Google/Bing, these 16 x 2 4/8-bit displays are used everywhere, Olimex/IAR/Keil ALL have working examples, go fish.

Try harder, or consider a different line of work.

\IAR Systems\Embedded Workbench 6.4 Kickstart\arm\examples\ST\STM32F10x\IAR-STM32-SK\LCD_Demo\app\main.c

Plenty of boards with displays, review schematics for wiring, demo software for examples.

If your specific display is magically different to others, refer to the data sheet.

Most people use the displays in 4-bit mode to use less pins, the abstraction is the same you just tell the display to use nibble mode, or NOT for 8-bit mode. they are pretty slow, so little benefit to using 8-bit bus.

Yet another Classic!
