The speed is set to 200kHz and can be configured by \ - modifying the relative define in stm32_eval_i2c_ee.h file.\ - \ - For M24C64 devices all the memory is accessible through the two-bytes \ - addressing mode and need to define block addresses. In this case, only the physical \ - address has to be defined (according to the address pins (E0,E1 and E2) connection).\ - This address is defined in i2c_ee.h (default is 0xA0: E0, E1 and E2 tied to ground).\ - The EEPROM addresses where the program start the write and the read operations \ - is defined in the main.c file. \ - \ - First, the content of Tx1_Buffer is 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 waits 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.\ - \ - All transfers are managed in DMA mode (except when 1-byte read/write operation is\ - required). Once sEE_ReadBuffer() or sEE_WriteBuffer() function is called, the \ - use application may perform other tasks in parallel while Read/Write operation is\ - managed by DMA.\ - \ - This example provides the possibility to use the STM32XXXX-EVAL LCD screen for\ - messages display (transfer status: Ongoing, PASSED, FAILED).\ - To enable this option uncomment the define ENABLE_LCD_MSG_DISPLAY in the main.c\ - file.
