Example Description

This example provides a basic example of how to use the SPI firmware library and an associate SPI SDcard driver to communicate with an SDcard available on The eval board.

The first step consist in filling the SPI Tx buffer. Then this last one is written on the micro sd cards. A comparison between the Buffer transmitted (Buffer_Block_Tx) and the received one (Buffer_Block_Rx) is done and LED1 is turned on in case of success otherwise LED2 is turned on.

Note:

The "system_stm32f0xx.c" is generated by an automatic clock configuration tool and can be easily customized to meet user application requirements. To select different clock setup, use the "STM32F0xx_Clock_Configuration_VX.Y.Z.xls" provided with the AN4055 package available on ST Microcontrollers

Hardware and Software environment

• This example runs on STM32F0xx devices.

• This example has been tested with STMicroelectronics STM320518-EVAL and STM32072B-EVAL including respectively STM32F051R8T6 and STM32F072VBT6 devices and can be easily tailored to any other supported device and development board

• STM320518-EVAL Set-up
  • MicroSD card is already available on this board.

• STM32072B-EVAL Set-up
  • MicroSD card is already available on this board.
