printf to LCD 16207

Altera_Forum · ‎09-10-2011

Hi,

My LCD routine works fine.I used the code from a template file in Eclipse. But i dun quite understand this template file.

Does anyone know how these 2 lines work??

FILE* fp;

fp= fopen(LCD_DISPLAY_NAME, "w");

Am i writing to the internal physical memory of the LCD module?? otherwise where is this file located at?

regards,

Michael

It's C language essentials. You create a pointer fp, which allocates some space in memory. Then You assign that memory space to LCD. Google "C writing to a file"
