关于最近driver lib的库函数调用问题

只看该作者 · 2015-4-25 11:32

我最近在跟着论坛学习driver lib的库函数调用，在读取iic的时候，不知道如何来使用这些封装好的函数，这是我改的官方的，大家帮忙看看哈，不知道怎么了，目前没搞定，
#include "driverlib.h"

#define SLAVE_ADDRESS 0x80

uint8_t transmitData0;
uint8_t transmitData1;
uint8_t receivedData;

void main(void)
{
//Stop WDT
WDT_A_hold(WDT_A_BASE);

//Assign I2C pins to USCI_B0
GPIO_setAsPeripheralModuleFunctionInputPin(
      GPIO_PORT_P3,
      GPIO_PIN0 + GPIO_PIN1
      );

//Initialize transmit data packet
transmitData0 = 0x81;
transmitData0 = 0xE0;

//Initialize Master
USCI_B_I2C_initMasterParam param = {0};
param.selectClockSource = USCI_B_I2C_CLOCKSOURCE_SMCLK;
param.i2cClk = UCS_getSMCLK();
param.dataRate = USCI_B_I2C_SET_DATA_RATE_100KBPS;
USCI_B_I2C_initMaster(USCI_B0_BASE, &param);

//Specify slave address
USCI_B_I2C_setSlaveAddress(USCI_B0_BASE,
                           SLAVE_ADDRESS
                           );

//Set in transmit mode
USCI_B_I2C_setMode(USCI_B0_BASE,
                     USCI_B_I2C_TRANSMIT_MODE
                     );

//Enable I2C Module to start operations
USCI_B_I2C_enable(USCI_B0_BASE);

USCI_B_I2C_clearInterrupt(USCI_B0_BASE,
                              USCI_B_I2C_RECEIVE_INTERRUPT
                              );
   USCI_B_I2C_enableInterrupt(USCI_B0_BASE,
                              USCI_B_I2C_RECEIVE_INTERRUPT
                              );

      //Send single byte data.
      USCI_B_I2C_masterSendSingleByte(USCI_B0_BASE,
                                    transmitData0
                                    );

      //Delay until transmission completes
      while(USCI_B_I2C_isBusBusy(USCI_B0_BASE))
      {
         ;
      }
      USCI_B_I2C_masterSendSingleByte(USCI_B0_BASE,
                                    transmitData1
                                    );

      //Delay until transmission completes
      while(USCI_B_I2C_isBusBusy(USCI_B0_BASE))
      {
         ;
      }

            USCI_B_I2C_masterReceiveSingleStart(USCI_B0_BASE);
            receivedData = USCI_B_I2C_masterReceiveSingle(
                        USCI_B0_BASE);

}
