ShiftLCD Library - CreateChar
|
||||
|
||||
Demonstrates the use a 16x2 LCD display. The ShiftLCD library works with
|
||||
all LCD displays that are compatible with the Hitachi HD44780 driver.
|
||||
There are many of them out there, and you can usually tell them by the
|
||||
16-pin interface.
|
||||
|
||||
This sketch prints "Hello, World!" and then adds a smiley after it
|
||||
|
||||
The circuit:
|
||||
|
||||
---Shift Register 74HC595---
|
||||
* SR Pin 14 to Arduino pin 2
|
||||
* SR Pin 12 to Arduino pin 3
|
||||
* SR Pin 11 to Arduino pin 4
|
||||
* SR Pin 8 to Ground
|
||||
* SR Pin 16 to +5v
|
||||
* SR Pin 13 to Ground
|
||||
* SR Pin 10 to +5v
|
||||
-----Shift Reg to LCD--------
|
||||
* SR Pin 15 to D7
|
||||
* SR Pin 1 to D6
|
||||
* SR Pin 2 to D5
|
||||
* SR Pin 3 to D4
|
||||
* SR Pin 5 to MOSFET gate
|
||||
* SR Pin 6 to Enable
|
||||
* SR Pin 7 to RS
|
||||
-----LCD HD44780-------------
|
||||
* Vss to Ground
|
||||
* Vdd to +5V
|
||||
* Vo to 10k Wiper
|
||||
* R/W to Ground
|
||||
* 5v to +5v
|
||||
* Gnd to MOSFET Drain
|
||||
------N Chanel MOSFET--------
|
||||
* Source to Ground
|
||||
* Gate to SP Pin 5
|
||||
* Drain to LCD Gnd
|
||||
* 1k Resistor Between gate and source
|
||||
