买的板子，DSP的电路是我自己做的。程序是用C2000的例程和网上找的430的程序结合改的。然后就是我用的是自带的SPI，数据是8位写，它自带的SPI是16位，写数就得这么写。。程序比较乱，谢谢您了。
#include "DSP28x_Project.h" // Device Headerfile and Examples Include File
// Prototype statements for functions found within this file.
// interrupt void ISRTimer2(void);

// Step 1. Initialize System Control:
// PLL, WatchDog, enable Peripheral Clocks
// This example function is found in the DSP2802x_SysCtrl.c file.
InitSysCtrl();
// Step 2. Initalize GPIO:
// This example function is found in the DSP2802x_Gpio.c file and
// illustrates how to set the GPIO to it's default state.
// InitGpio(); // Skipped for this example
// Setup only the GP I/O only for SPI-A functionality
// This function is found in DSP2802x_Spi.c
InitSpiaGpio();
// Step 3. Clear all interrupts and initialize PIE vector table:
// Disable CPU interrupts
DINT;
// Initialize 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 DSP2802x_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 DSP2802x_DefaultIsr.c.
// This function is found in DSP2802x_PieVect.c.
InitPieVectTable();
// Step 4. Initialize all the Device Peripherals:
// This function is found in DSP2802x_InitPeripherals.c
// InitPeripherals(); // Not required for this example
spi_fifo_init(); // Initialize the Spi FIFO
spi_init(); // init SPI
EALLOW;
SpiaRegs.SPICTL.bit.TALK=1;

// Step 7. Insert all local Interrupt Service Routines (ISRs) and functions here:

for (i = 0; i < b; i++) {}
}
void delay_loop()
{

}

}
void spi_init()
{
SpiaRegs.SPICCR.all =0x0007; // Reset on, rising edge, 16-bit char bits
SpiaRegs.SPICTL.all =0x000E; // Enable master mode, normal phase,
// enable talk, and SPI int disabled.
SpiaRegs.SPIBRR =0x001F;
SpiaRegs.SPICCR.all =0x0087; // Relinquish SPI from Reset
SpiaRegs.SPIPRI.bit.FREE = 1; // Set so breakpoints don't disturb xmission
