TMS570LS3137: I2C issue

Hello,

I have a problem using I2C. I am trying to send data from the TMS570 (master mode) to a STS-35, a slave digital temperature sensor. However, the MCU does not send data. I used the examples of HALCoGen to use it.

The code is as follows:

    //STS35 measurement

    uint8_t tpu = 0;

    for(i = 0; i<255; i++)
        for (tpu = 0; tpu<5; tpu++);

    /* Configure address of Slave to talk to */
    i2cSetSlaveAdd(i2cREG1, STS35_Address);
    sciSend(scilinREG, 22, (unsigned char *)"I2C Slave configured\r\n");

    /* Set direction to Transmitter */
    /* Note: Optional - It is done in Init */
    i2cSetDirection(i2cREG1, I2C_TRANSMITTER);
    sciSend(scilinREG, 41, (unsigned char *)"I2C Direction to transmitter configured\r\n");

    /* Configure Data count */
    /* Data Count ( Word Address) */
    i2cSetCount(i2cREG1, STS35_bsize);
    sciSend(scilinREG, 27, (unsigned char *)"I2C Data Count configured\r\n");

    /* Set mode as Master */
    i2cSetMode(i2cREG1, I2C_MASTER);
    sciSend(scilinREG, 28, (unsigned char *)"I2C Master mode configured\r\n");

    /* Set Stop after programmed Count */
    i2cSetStop(i2cREG1);
    sciSend(scilinREG, 25, (unsigned char *)"I2C Stop bit configured\r\n");

    /* Transmit Start Condition */
    i2cSetStart(i2cREG1);
    sciSend(scilinREG, 26, (unsigned char *)"I2C Start bit configured\r\n");

    /* Transmit DATA_COUNT number of data in Polling mode */
    i2cSend(i2cREG1, STS35_bsize, TX_PACK);
    sciSend(scilinREG, 16, (unsigned char *)"I2C sent bytes\r\n");

    /* Wait until Bus Busy is cleared */
    while(i2cIsBusBusy(i2cREG1) == true);
    sciSend(scilinREG, 22, (unsigned char *)"I2C bus Busy cleared\r\n");

    /* Wait until Stop is detected */
    while(i2cIsStopDetected(i2cREG1) == 0);
    sciSend(scilinREG, 19, (unsigned char *)"I2C Stop detected\r\n");

    /* Clear the Stop condition */
    i2cClearSCD(i2cREG1);
    sciSend(scilinREG, 18, (unsigned char *)"I2C Stop cleared\r\n");

    /* Simple Dealay before starting Next Block */
    /* Depends on how quick the Slave gets ready */
    for(i = 0; i<255; i++)
        for (tpu = 0; tpu<40; tpu++);

The program remains in /* Wait until Stop is detected */ waiting for a Stop bit. I tried to measure the frame with my OSC but I could not detect any bit on SDA or SCLK.

Thank you so much.

Regards,

Leandro
