I just setup this forum and have not yet figured out how to get emails sent to me when someone posts! I think your problem is in the Lcd constructor, try this: <pre><code>#include <Lcd.h> // LCD module is 16 columns wide, 4 pin mode, 2 lines Lcd lcd = Lcd(16, FUNCTION_4BIT | FUNCTION_2LINE); void setup() { // for the sake of demonstration change pin assignment lcd.set_ctrl_pins(CTRLPINS(1,2,3)); // RS->1, RW->2, E->3 lcd.set_data_pins(_4PINS(4,5,6,7)); // D4->4, D5->5, D6->6, D7->7 lcd.setup(); // setup arduino and initialize LCD } void loop() { lcd.home(); lcd.print("Line 1"); lcd.move_to(1, 2); lcd.print("Line 2"); }</code></pre> jkittle99 on "There's nothing here?" http://forum.slashdev.ca/topic/2#post-2 Thu, 07 Jan 2010 23:15:37 +0000 jkittle99 2@http://forum.slashdev.ca/ Seriously? Ok so let me be the first, then. I'm using Arduino 17 on a mac. The library works fine. I've wired up a 2x16 Winstar WH1602B display (it has an RGB backlight - mega cool) and I'm running in 4 bit mode. Hello world works fine on line 1, but nothing goes to line 2. Why is "move_to" not highlighted? My complete code: /* * Simple hello world program in 4 pin mode. */ #include <Lcd.h> // LCD module is 16 columns wide, use 4 pin mode Lcd lcd = Lcd(16, FUNCTION_4BIT); char msg[] = "Hello, World!"; void setup() { // for the sake of demonstration change pin assignment lcd.set_ctrl_pins(CTRLPINS(1,2,3)); // RS->1, RW->2, E->3 lcd.set_data_pins(_4PINS(4,5,6,7)); // D4->4, D5->5, D6->6, D7->7 lcd.setup(); // setup arduino and initialize LCD lcd.move_to(1,2); lcd.print("Line 2"); } void loop() { lcd.home(); // return cursor to home possition lcd.print(msg); // print the ever so familiar message }
