// FILE: Example_2833xI2c_eeprom.c
//
// TITLE: DSP2833x I2C EEPROM Example
//
// ASSUMPTIONS:
//
// This program requires the DSP2833x header files.
//
// This program requires an external I2C EEPROM connected to
// the I2C bus at address 0x50.
//
// As supplied, this project is configured for "boot to SARAM"
// operation. The 2833x Boot Mode table is shown below.
// For information on configuring the boot mode of an eZdsp,
// please refer to the documentation included with the eZdsp,
//
// $Boot_Table:
//
// GPIO87 GPIO86 GPIO85 GPIO84
// XA15 XA14 XA13 XA12

// 0 0 0 1 Boot to SARAM, bypass ADC cal

//
// DESCRIPTION:
//
// This program will write 1-14 words to EEPROM and read them back.
// The data written and the EEPROM address written to are contained
// in the message structure, I2cMsgOut1. The data read back will be
// contained in the message structure I2cMsgIn1.
//
// This program will work with the on-board I2C EEPROM supplied on
// the F2833x eZdsp.

// Step 2. Initalize GPIO:
// This example function is found in the DSP2833x_Gpio.c file and
// illustrates how to set the GPIO to it's default state.
// InitGpio();
// Setup only the GP I/O only for I2C functionality
// 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 DSP2833x_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 DSP2833x_DefaultIsr.c.
// This function is found in DSP2833x_PieVect.c.

// Interrupts that are used in this example are re-mapped to
// ISR functions found within this file.

// Step 4. Initialize all the Device Peripherals:
// This function is found in DSP2833x_InitPeripherals.c
// InitPeripherals(); // Not required for this example
// Step 5. User specific code
// Enable interrupts required for this example
// Enable CPU INT8 which is connected to PIE group 8

看着不错，可以试试看，也是刚开学习，先跑个程序试试
