Part Number: TMS320F28379D
Other Parts Discussed in Thread: C2000WARE

Hello.,

I need an code in which it displays 1 or o in oscilloscope using if statement ,if gpio pin is 44 it should display 1 in oscilloscope in wave and for pin 49 it should display 0.,the number should be dynamic depends on the user.i am using code composer studio to build the code

Example:

If(GPIO44=0){

{

GPIO=1

}

if(GPIo49=1)

{

GPIO = 0

}

    #include "F2837xD_device.h" 
    #include "F2837xD_Examples.h" 

    void main(void)
    {
    // Initialize system
    InitSysCtrl();


    GPIO_SetupPinMux(44, GPIO_MUX_CPU1, 0);
    GPIO_SetupPinOptions(44, GPIO_INPUT, GPIO_PUSHPULL);
    GPIO_SetupPinMux(45, GPIO_MUX_CPU1, 0);
    GPIO_SetupPinOptions(45, GPIO_INPUT, GPIO_PUSHPULL);

    // Main loop
    while (1)
    {

    if (GpioDataRegs.GPADAT.bit.GPIO44 == 1)
    {

    GpioDataRegs.GPASET.bit.GPIO44 = 1;
    }
    else
    {

    GpioDataRegs.GPACLEAR.bit.GPIO44 = 1;
    }


    if (GpioDataRegs.GPADAT.bit.GPIO45 == 0)
    {

    GpioDataRegs.GPACLEAR.bit.GPIO45 = 0;
    }
    else
    {

    GpioDataRegs.GPASET.bit.GPIO45 = 1;
    }
    }
    }

    "Is this program correct? Will it output a signal of 1 for GPIO pin 44 and a signal of 0 for GPIO pin 45? I am planning to observe the output using an oscilloscope, which displays high and low signals. If there are any corrections needed, please let me know."

    Hi Arun,

    Have you tried out this example from your side? Where you able to observe the GPIO ON/OFF?

    Please have a look at the GPIO example from the C2000Ware SDK and let me know if you have any other query.

    Thanks
