This example is based on the STM32F1xx SPI LL API. The peripheral initialization uses LL unitary service functions for optimization purposes (performance and size). This example works with only one STM32F103RB-Nucleo. SPI1 Peripheral is configured in Master mode Half-Duplex Tx. SPI2 Peripheral is configured in Slave mode Half-Duplex Rx. GPIO associated to User push-button is linked with EXTI. Example execution: LED2 is blinking Fast (200ms) and wait User push-button action. Press User push-button on BOARD start a Half-Duplex communication through IT. On MASTER side (SPI1), Clock will be generated on SCK line, Transmission done on MOSI Line. On SLAVE side (SPI2) reception is done through the MISO Line. LED2 is On if data is well received. In case of errors, LED2 is blinking Slowly (1s). @par Directory contents - SPI/SPI_OneBoard_HalfDuplex_IT/Inc/stm32f1xx_it.h Interrupt handlers header file - SPI/SPI_OneBoard_HalfDuplex_IT/Inc/main.h Header for main.c module - SPI/SPI_OneBoard_HalfDuplex_IT/Inc/stm32_assert.h Template file to include assert_failed function - SPI/SPI_OneBoard_HalfDuplex_IT/Src/stm32f1xx_it.c Interrupt handlers - SPI/SPI_OneBoard_HalfDuplex_IT/Src/main.c Main program - SPI/SPI_OneBoard_HalfDuplex_IT/Src/system_stm32f1xx.c STM32F1xx system source file @par Hardware and Software environment - This example runs on STM32F103xB devices. - This example has been tested with STM32F103RB-Nucleo board and can be easily tailored to any other supported device and development board. - STM32F103RB-Nucleo Set-up - Connect Master SCK PB3 to Slave SCK PB13 - Connect Master MOSI PB5 to Slave MISO PB14 Relation with Board connector: PB3 is connected to pin 31 of CN10 connector PB5 is connected to pin 29 of CN10 connector PB13 is connected to pin 30 of CN10 connector PB14 is connected to pin 28 of CN10 connector @par How to use it ? In order to make the program work, you must do the following : - Open your preferred toolchain - Rebuild all files and load your image into target memory - Run the example *
