This program is a routine for controlling LEDs on TMS320F28377D. You need to build a CCS project and compile and run it yourself.

// Step 1. Initialize System Control:
// PLL, WatchDog, enable Peripheral Clocks
// This example function is found in the F2837xD_SysCtrl.c file.
//
InitSysCtrl();
//
// Step 2. Initialize GPIO:
// This example function is found in the F2837xD_Gpio.c file and
// illustrates how to set the GPIO to it's default state.
//
InitGpio();
GPIO_SetupPinMux(BLINKY_LED_GPIO, GPIO_MUX_CPU1, 0);
GPIO_SetupPinOptions(BLINKY_LED_GPIO, GPIO_OUTPUT, GPIO_PUSHPULL);
//
// Step 3. Clear all interrupts and initialize PIE vector table:
// Disable CPU interrupts
//
DINT;
//
// Initialize the PIE control registers to their default state.
// The default state is all PIE interrupts disabled and flags
// are cleared.
// This function is found in the F2837xD_PieCtrl.c file.
//
InitPieCtrl();
//
// Disable CPU interrupts and clear all CPU interrupt flags:
//
IER = 0x0000;
IFR = 0x0000;
//
// Initialize the PIE vector table with pointers to the shell Interrupt
// Service Routines (ISR).
// This will populate the entire table, even if the interrupt
// is not used in this example. This is useful for debug purposes.
// The shell ISR routines are found in F2837xD_DefaultIsr.c.
// This function is found in F2837xD_PieVect.c.
//
InitPieVectTable();
//
// Enable global Interrupts and higher priority real-time debug events:
//
EINT; // Enable Global interrupt INTM
ERTM; // Enable Global realtime interrupt DBGM
//
// Step 6. IDLE loop. Just sit and loop forever (optional):
//
for(;;)
{
//
// Turn on LED
//
GPIO_WritePin(BLINKY_LED_GPIO, 0);
//
// Delay for a bit.
//
DELAY_US(1000*500);
//
// Turn off LED
//
GPIO_WritePin(BLINKY_LED_GPIO, 1);
//
// Delay for a bit.
//
DELAY_US(1000*500);
}
}
//
// End of file
//
