3 C2000 I2C Source Code

The C2000Ware software example provided in Table 3-1 shows how to use I2C module to communicate with EEPROM via I2C bus. This example has been developed for EEPROM AT24C256, which requires 2 bytes for addressing the EEPROM memory with slave address of 0x50. Table 3-2 shows the I2C interrupts used in EEPROM interrupt based example.
