  1. I believe to have all connections correct from the launchpad to my breadboard, but when I connect VCC to my board the LCD just flickers some vertical lines and then the LCD goes dark again. Anyone have an suggestions? /* The circuit: ================================= LCD pin Connect to --------------------------------- 01 - GND GND, pot 02 - VCC +5V, pot 03 - Contrast Pot wiper 04 - RS Pin8 (P2.0) 05 - R/W GND 06 - EN Pin9 (P2.1) 07 - DB0 GND 08 - DB1 GND 09 - DB2 GND 10 - DB3 GND 11 - DB4 Pin10 (P2.2) 12 - DB5 Pin11 (P2.3) 13 - DB6 Pin12 (P2.4) 14 - DB7 Pin13 (P2.5) 15 - BL+ +5V 16 - BL- GND ================================= */ // include the library code: #include <LiquidCrystal.h> // initialize the library with the numbers of the interface pins LiquidCrystal lcd(P2_0, P2_1, P2_2, P2_3, P2_4, P2_5); void setup() { // set up the LCD's number of columns and rows: lcd.begin(16, 2); // Print a message to the LCD. lcd.print("hello, world!"); analogReference(DEFAULT); } void loop() { // set the cursor to column 0, line 1 // (note: line 1 is the second row, since counting begins with 0): lcd.setCursor(0, 1); // print the number of seconds since reset: lcd.print(millis()/1000); }
