Other Parts Discussed in Thread: AFE4900
Tool/software: Code Composer Studio
Hello, I download the TIDCEM3A-TIDA-01580 Firmware. I use the part of AFE4900_Reg_Init( IIC interface ). But it doesn't work. What else should I pay attention to?
I2C_Params_init(&i2cParams);
i2cParams.bitRate = I2C_100kHz;
i2c_4900 = I2C_open(Board_I2C_TMP, &i2cParams);
if (i2c_4900 == NULL) {
Log_info0("Error Initializing I2C\n");
while (1);
}
else {
Log_info0("I2C Initialized!\n");
}
PIN_setOutputValue(userGPIOpinHandle, PIN_AFE_RESETZ, 1);
Task_sleep(500);
PIN_setOutputValue(userGPIOpinHandle, PIN_AFE_RESETZ, 0);
Task_sleep(500);
PIN_setOutputValue(userGPIOpinHandle, PIN_AFE_RESETZ, 1);
Task_sleep(500);
if ( PIN_registerIntCb(userGPIOpinHandle, pinIntHandler) != PIN_SUCCESS ) {
/* Error registering button callback function */
while(1);
}
// initStatHRM(); // Initialize HRM variables
SEM_adcRdy_risingEdge = SemaphoreP_createBinary(1);
if (SEM_adcRdy_risingEdge == NULL)
{
while(1);
}
i=0;
while( AFE_ppg_ecg_reg_arr[i][0] != 0xFF ){
AFE4900_Reg_Write( AFE_ppg_ecg_reg_arr[i][0], AFE_ppg_ecg_reg_arr[i][1] );
if( AFE_ppg_ecg_reg_arr[i][0] == 0x4E ){
if( (AFE_ppg_ecg_reg_arr[i][1] >> 12) & 1 ){ // get Leadoff bit
leadOffMode = LEADOFF_MODE_AC;
}else{
leadOffMode = LEADOFF_MODE_DC;
}
}
i++;
