I2C1 is configured in Master transmitter during write operation and in Master receiver during read operation from I2C EEPROM. The speed is set to the maximum frequency of 400kHz. This value is defined in the I2c_ee.c file, which could be in the range of 0 to 400KHZ. One I2C EEPROM Block address where the program will write the buffer have to be selected from the four address available and defined in the I2c_ee.h file. The EEPROM address where the program start the write and the read operations is defined in the main.c file. First, the contents of Tx1_Buffer are written to the EEPROM_WriteAddress1 and the written data are read. The written and the read buffers data are then compared. Following the read operation, the program wait that the EEPROM reverts to its Standby state. A second write operation is, then, performed and this time, Tx2_Buffer is written to EEPROM_WriteAddress2, which represents the address just after the last written one in the first write. After completion of the second write operation, the written data are read. The contents of the written and the read buffers are compared.

How to use it ============= In order to make the program work, you must do the following : - Create a project and setup all your toolchain's start-up files - Compile the directory content files and required Library files : + stm32f10x_lib.c + stm32f10x_i2c.c + stm32f10x_rcc.c + stm32f10x_nvic.c + stm32f10x_gpio.c + stm32f10x_flash.c - Link all compiled files and load your image into target memory - Run the example ******************* (C) COPYRIGHT 2008 STMicroelectronics *****END OF FILE******
