Hi TI and other great guys.
I have a confusing about data format could different with define value.
Could you please help me check as below code have any mistake of define issue?
Thanks,
Eric.
#define SLAVE_DEVICE 0x48
#define I2C_DATA 0x68
int main(void) {
WDT_A_hold(WDT_A_BASE);
//Assign I2C pins to USCI_B0
GPIO_setAsPeripheralModuleFunctionInputPin(GPIO_PORT_P3, GPIO_PIN0 | GPIO_PIN1);
//Disable I2C Module to start operations
USCI_B_I2C_disable(USCI_B0_BASE);
//Initialize Master mode
USCI_B_I2C_initMasterParam i2cParamSet = {USCI_B_I2C_CLOCKSOURCE_SMCLK, UCS_getSMCLK(), USCI_B_I2C_SET_DATA_RATE_400KBPS};
USCI_B_I2C_initMaster(USCI_B0_BASE, &i2cParamSet);
//Specify slave address
USCI_B_I2C_setSlaveAddress(USCI_B0_BASE, SLAVE_DEVICE); <= Why does the define name of SLAVE_DEVICE value will become ascii code of "H"?
//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);
//Send single byte data.
USCI_B_I2C_masterSendSingleByte(USCI_B0_BASE, I2C_DATA); <= Why does the define name of SLAVE_DEVICE value will become ascii code of "h"?
//Delay until transmission completes
while(USCI_B_I2C_isBusBusy(USCI_B0_BASE)){;}
}
