This demo is based on the GD32307C-EVAL-V1.1 board, it provides a description
of how to use the I2C bus to write and read EEPROM by interrupt. The access result
will be printed by COM0.
Procedures sequentially writes 256 bytes of data to the EEPROM from the 0x00
address, and then the program sequentially reads 256 bytes of data from the
EEPROM from the 0x00 address. Compare the written data and read data, if the
same,"I2C-AT24C02 test passed!" will be printed, while the board of the four
LED lights start flashing, otherwise "Err:data read and write aren't matching."
will be printed, while the four LEDs light will on.
P4 should be fitted to I2C and JP5 must be fitted to the USART port.
