// 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:

// 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.

// 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.

// 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.

// Enable CPU INT8 which is connected to PIE group 8

看著不錯(cuò)，可以試試看，也是剛開學(xué)習(xí)，先跑個(gè)程序試試

我用的是5502芯片液晶也是12864的能顯示嘛
