Other Parts Discussed in Thread: HALCOGEN, TMS570LS0432

hello team

im working with TMS570LS0432 controller with MIBSPI module.my slave device is 23LC1024 SRAM device.have configured using the HALCOGEN version4 .this my code

uint16 TX_Data[]={0xAA,0x55};

            uint16 RX_Data[2];

            mibspiInit(); //initializes the mibspi modul

                      mibspiSetData(mibspiREG1,0,TX_Data);//Set Buffer Data to the transfer group0

            mibspiTransfer(mibspiREG1,0);//Initiates a transfer for the  transfer group0.

            while(!(mibspiIsTransferComplete(mibspiREG1,0))); //Checks to see if the transfer for the specified transfer group0 has finished.

            mibspiGetData(mibspiREG1,0,RX_Data);//Retrieves Buffer Data from receive buffer

            while(1);

for interfacing with sram

but m unable to read and write.plz help me.

thanks in advance

    hello team,

    im workin with tms570ls0432 microcontroller. im using the mibspi module.have configured using the halcogen version4.should send and recieve data from sram 23lc1024.the code i have used is

    /* USER CODE BEGIN (2) */
    uint16 txBuffer[]={0xaa,0X55};
    uint16 rxBuffer[1];
    /* USER CODE END */

    void main(void)
    {
    /* USER CODE BEGIN (3) */
        while(1)
        {
        mibspiInit();//initializes the mibspi module

        mibspiSetData(mibspiREG1,0,txBuffer);//Set Buffer Data to the transfer group0

        mibspiTransfer(mibspiREG1,0);//Initiates a transfer for the  transfer group0.

        while((mibspiIsTransferComplete(mibspiREG1,0))); //Checks to see if the transfer for the specified transfer group0 has finished.

        mibspiGetData(mibspiREG1,0,rxBuffer);//Retrieves Buffer Data from receive buffer
        }.

    the interface connection with sram is

    but while workin with ccs im unable to read and write data while debugging.i dont know where i went wrong.can you plz help me.

    Hello:

    Are you able to see the data in the MOSI/MISO lines using a scope? Could you try using loopback mode and checking the outcome? After calling mibspiInit() call mibspiEnableLoopback(mibspiREG1, Digital_Lbk)

    Regards,

    Enrique

    hello

    thank you. when i tried with the looback mode im able transmit and recieved data.but as i know loopbackmode is the self test mode.since i have to communicate with the slave device (23LC1024-SRAM DEVICE)my code goes wrong.

    have to write a code so that i can read and write data from slave device using mibspi module in tms570ls0432.can you help me in this.thanks in advance
