Hi everyone!
I need some help...I'm trying to use I2C bus on micaz communicate with a LCD
I2C display... The program that I'm writing is very simple and I'm showing
below:
My configuration file:
configuration MasterAppC
{
}
implementation
{
components MainC, LedsC, MasterC;
components new Atm128I2CMasterC();
MasterC -> MainC.Boot;
MasterC.Leds -> LedsC;
MasterC.Resource -> Atm128I2CMasterC;
MasterC.I2C -> Atm128I2CMasterC;
}
My program file:
#include "I2C.h"
module MasterC
{
uses interface Leds;
uses interface Boot;
uses interface I2CPacket<TI2CBasicAddr> as I2C;
uses interface Resource;
uses interface GeneralIO as IO;
}
implementation
{
event void Boot.booted()
{
call Resource.request(); //pedido acesso ao I2c...
}
event void Resource.granted() //acesso ao I2C concedido...
{
static uint8_t Buffer[2]= { 12, 19};
if (call I2C.write(I2C_START | I2C_STOP, 0xC6, sizeof Buffer, Buffer)
== SUCCESS)
{
call Leds.led1On();
}
}
async event void I2C.readDone(error_t error, uint16_t addr, uint8_t
length, uint8_t* data)
{
call Leds.led0On();
call Resource.release();
}
async event void I2C.writeDone(error_t error, uint16_t addr, uint8_t
length, uint8_t* data)
{
call Leds.led0On();
}
}
My Makefile:
COMPONENT=MasterAppC
SENSORBOARD=mts300
include $(MAKERULES)
This program have no compile errors but I don't have any response from
LCD...I'm using ubuntu 9.1...I also used a digital osciloscope to see the
DATA and CLOCK signals but they always stays at 0! I'm wondering if I have
to add some command to the makefile...because I have no idea why this don't
works...
