Joystick v2.0 – Greedy Freak Game
Hi Guys, Joystick v2.0 is our new product which added Nokia 5110 LCD and nRF24L01 interface. You can easy develop your Joystick games, and even communication each other with wireless nRF24L01.
I just made a simple demo game base on Joystick Game Kit, we called — Greedy Freak.
Take a look first:
If you want to write your own Joystick game, fellow me and look what are you need preparation.
Hareware
- Joystick v2.0
- Freaduino ATmage328
- Nokia 5110 LCD
- nRF24L01 (Non-essential)
We have prepare Joystick Game Kit for starter now, there is no soldering required and you can start your project quickly. Another important reason choose the Joystick Game Kit is the Joystick v2.0 with Nokia5110 is not support standard Arduino board Because of standard Arduino board 3.3v just supply 50mA current, which can’t support Nokia5110 backlight need. But our Freaduino support 800mA current which far more than Nokia5110′s demand.
Software Greedy Freak is base on a Nokia 5110 LCD library – LCD5110_Graph library written by our friend Henning Karlsen. Put the library to your \arduino-00xx\libraries\. The LCD 5110 pin define with Arduino as below:
SCLK – D9 , MOSI – D10 , D/C – D11 , RST – D12 , SCE – D13
LCD5110 myGLCD(9,10,11,12,13);
The nRF24L01 pin define with Arduino as:
SCE – D9 , CSN – D10 , SCK – D13 , MOSI – D11 , MISO – D12
#define CE 9
// CE_BIT: Digital Input Chip Enable Activates RX or TX mode
#define CSN 10
// CSN BIT: Digital Input SPI Chip Select
#define SCK 13
// SCK BIT: Digital Input SPI Clock
#define MOSI 11
// MOSI BIT: Digital Input SPI Slave Data Input
#define MISO 12
// MISO BIT: Digital Output SPI Slave Data Output, with tri-state option
Because of the data pin with Nokia 5110 and nRF24L01 is multiplexing, the demo game no support them at same time. Maybe we can design another Joystick Mage2560 for more IO in future. Now, Greedy Freak full code just as below, you can see it’s realy simple.
