標(biāo)題: DSP2833x例程GPIO_output_LED
源程序如下:
  1. #include "DSP2833x_Device.h"     // DSP2833x Headerfile Include File
  2. #include "DSP2833x_Examples.h"   // DSP2833x Examples Include File

  4. #define          LED1        GpioDataRegs.GPADAT.bit.GPIO0
  5. #define          LED2        GpioDataRegs.GPADAT.bit.GPIO1
  6. #define          LED3        GpioDataRegs.GPADAT.bit.GPIO2
  7. #define          LED4        GpioDataRegs.GPADAT.bit.GPIO3
  8. #define          LED5        GpioDataRegs.GPADAT.bit.GPIO4

  10. void configtestled(void);

  12. void main(void)
  13. {
  14. // Step 1. Initialize System Control:
  15. // PLL, WatchDog, enable Peripheral Clocks
  16. // This example function is found in the DSP2833x_SysCtrl.c file.
  17.    InitSysCtrl();

  19. // Step 2. Initalize GPIO:
  20. // This example function is found in the DSP2833x_Gpio.c file and
  21. // illustrates how to set the GPIO to it's default state.
  22. // InitGpio();  // Skipped for this example
  23.    InitXintf16Gpio();        //zq

  25. // Step 3. Clear all interrupts and initialize PIE vector table:
  26. // Disable CPU interrupts
  27.    DINT;

  29. // Initialize the PIE control registers to their default state.
  30. // The default state is all PIE interrupts disabled and flags
  31. // are cleared.
  32. // This function is found in the DSP2833x_PieCtrl.c file.
  33.    InitPieCtrl();

  35. // Disable CPU interrupts and clear all CPU interrupt flags:
  36.    IER = 0x0000;
  37.    IFR = 0x0000;

  39. // Initialize the PIE vector table with pointers to the shell Interrupt
  40. // Service Routines (ISR).
  41. // This will populate the entire table, even if the interrupt
  42. // is not used in this example.  This is useful for debug purposes.
  43. // The shell ISR routines are found in DSP2833x_DefaultIsr.c.
  44. // This function is found in DSP2833x_PieVect.c.
