The speed is set to 200kHz and can be configured to -other values by setting the define I2C_SPEED in stm32_eval_i2c_ee.h file. -All transfers are performed through DMA access (except for One Byte Receiving case) -which allows user application to perform parallel tasks while transfer to/from -EEPROM is ongoing. - -For M24C02 to M24C16 devices, 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 stm32_eval_i2c_ee.h file. - -For M24C32 and 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 stm32_eval_i2c_ee.c.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. - - -@par Directory contents - - - I2C/EEPROM/stm32f10x_conf.h Library Configuration file - - I2C/EEPROM/stm32f10x_it.c Interrupt handlers - - I2C/EEPROM/stm32f10x_it.h Interrupt handlers header file - - I2C/EEPROM/main.c Main program - - I2C/EEPROM/system_stm32f10x.c STM32F10x system source file - -@par Hardware and Software environment - - - This example runs on STM32F10x Connectivity line, High-Density, High-Density - Value line, Medium-Density, XL-Density, Medium-Density Value line, Low-Density - and Low-Density Value line Devices. - - - This example has been tested with STM32100E-EVAL (STM32F10x High-Density Value - line) evaluation board (implemented EEPROM is M24C64) and STM3210C-EVAL - (STM32F10x Connectivity-Line) evaluation board (implemented EEPROM is M24C64) - with no additional hardware, and can be easily tailored to any other supported - device and development board. - - - STM32100E-EVAL Set-up - - Make sure the jumper JP14 "ROM_WP" is fitted on the board. - - No additional Hardware connections are needed. - - - - STM3210C-EVAL Set-up - - Make sure the Jumper JP17 "I2C_SCK" is fitted on the board. - - Make sure the jumper JP9 "ROM_WP" is fitted on the board. - - No additional Hardware connections are needed. - -@par How to use it ? - -In order to make the program work, you must do the following : - - Copy all source files from this example folder to the template folder under - Project\STM32F10x_StdPeriph_Template - - Open your preferred toolchain - - Rebuild all files and load your image into target memory - - Run the example - -@note - - Low-density Value line devices are STM32F100xx microcontrollers where the - Flash memory density ranges between 16 and 32 Kbytes. - - Low-density devices are STM32F101xx, STM32F102xx and STM32F103xx - microcontrollers where the Flash memory density ranges between 16 and 32 Kbytes. - - Medium-density Value line devices are STM32F100xx microcontrollers where - the Flash memory density ranges between 64 and 128 Kbytes. - - Medium-density devices are STM32F101xx, STM32F102xx and STM32F103xx - microcontrollers where the Flash memory density ranges between 64 and 128 Kbytes. - - High-density Value line devices are STM32F100xx microcontrollers where - the Flash memory density ranges between 256 and 512 Kbytes. - - High-density devices are STM32F101xx and STM32F103xx microcontrollers where - the Flash memory density ranges between 256 and 512 Kbytes. - - XL-density devices are STM32F101xx and STM32F103xx microcontrollers where - the Flash memory density ranges between 512 and 1024 Kbytes. - - Connectivity line devices are STM32F105xx and STM32F107xx microcontrollers. - - * <h3><center>© COPYRIGHT 2011 STMicroelectronics</center></h3> - */ |
