thats the board im using. yeah i already know the code for printing something on the lcd and here is the code
- include "mbed.h"
- include "MCP23017.h"
- include "WattBob_TextLCD.h"
- define BACK_LIGHT_ON(INTERFACE) INTERFACE->write_bit(1,BL_BIT)
- define BACK_LIGHT_OFF(INTERFACE) INTERFACE->write_bit(0,BL_BIT) MCP23017 *par_port; WattBob_TextLCD *lcd; int main() { par_port = new MCP23017(p9, p10, 0x40); lcd = new WattBob_TextLCD(par_port); par_port->write_bit(1,BL_BIT); lcd->cls(); lcd->locate(0,0); lcd->printf("HI FUNDROID TEAM"); for(;;); }
no i cant read a button!!
Which board are you using together with your lpc1768? Since that doesn't have 4 switch buttons.
Also how far did you get yourself? Can you already print something on your LCD? Can you read a button?
