Connecting MSP430F5528 to ADS1248 via SPI

Wayne,

For this kind of questions, i would suggest you to either look in E2E, the TI processors wiki, or you can find the link to the MSP430 app note collection here:

http://processors.wiki.ti.com/index.php/MSP430_FAQ#Where_can_i_find_the_list_of_MSP430_application_notes.3F

just use the keyword "ADS" for the app note search and you can find some app notes - not exactly for ADS1248, but at least can be as your reference.

Hi Leo Hendrawan,

Thanks for your replying.

In my case, the hardware design almost finished. Right now I need some software program help--example code of ADS1248..

Regards,

Wayne

Dear,

I am working on MSP430F6736 and I am using UART in AUTO BAUDRATE mode and this is my clock initialization function:

void Clock_Init()
{
    //Set DCO FLL reference = REFO
    UCS_clockSignalInit(
              UCS_BASE,
              UCS_FLLREF,
              UCS_REFOCLK_SELECT,
              UCS_CLOCK_DIVIDER_1
              );
    //Set Ratio and Desired MCLK Frequency  and initialize DCO
    UCS_initFLLSettle(
              UCS_BASE,
              12000,
              366
              );
}

And my UART initialization is like below :

UCA1ABCTL |= UCABDEN;

Uart_Init(UARTA1,9600);                                // Initialize UART Modules

And Uart_Init function is like below :

//P1.4,5 = USCI_A1 TXD/RXD
        GPIO_setAsPeripheralModuleFunctionOutputPin(
                GPIO_PORT_P1,
                GPIO_PIN4
                );

        GPIO_setAsPeripheralModuleFunctionInputPin(
                GPIO_PORT_P1,
                GPIO_PIN5
                );

        //Initialize USCI UART module

        if ( STATUS_FAIL == EUSCI_UART_init(EUSCI_A1_BASE,
                             EUSCI_UART_CLOCKSOURCE_SMCLK,
                             UCS_getSMCLK(UCS_BASE),
                             BAUD_RATE,
                             EUSCI_UART_NO_PARITY,
                             EUSCI_UART_LSB_FIRST,
                             EUSCI_UART_ONE_STOP_BIT,
                             EUSCI_UART_MODE,
                             EUSCI_UART_LOW_FREQUENCY_BAUDRATE_GENERATION ))

        {
            return;
        }

        //Enable UART module for operation
        EUSCI_UART_enable(EUSCI_A1_BASE);

But I am not getting perfect output if i change baudrate of hyper terminal.

And my program is of ECHO test using interrupt.

Please Reply on this coz i am stuck here badly.

Thanx in advance.
