B-U585I-IOT02A_SPI

• This exampele shows how to configure and use the SPI interfaces connected to the Arduino and STMOD2 on the B-U585I-IOT02A board

• Two SPI interfaces configured. SPI1 and SPI3.

• SPI1 is connected to the ARDUINO connector

• SPI3 is connected to the STMOD+ 2 connector.

ARDUINO Pins connections

• ARD_D13: SPI1_SCK (ARD_SPI_SCK)
• ARD_D12: SPI1_MISO (ARD_SPI_MISO)
• ARD_D11: SPI1_MOSI (ARD_SPI_MOSI)
• ARD_D10: SPI1_NSS (ARD_SPI_NSS)

STMOD+2 Pins connections

• STMOD2_1: SPI3_NSS (STMOD2_SPI_NSS)
• STMOD2_2: SPI3_MOSI (STMOD2_SPI_MMOSI)
• STMOD2_3: SPI3_MISO (STMOD2_SPI_MISO)
• STMOD2_4: SPI3_SCK (STMOD2_SPI_SCK)

Code examples

USE SPI1 connected to ARDUINO

HAL_GPIO_WritePin      ( ARD_SPI_NSS_GPIO_Port, ARD_SPI_NSS_Pin, GPIO_PIN_RESET);
HAL_SPI_TransmitReceive(&ARD_SPI, tx_data_2, rx_data_2,DATA_SIZE_2, 0xFFFFFFFF);
HAL_GPIO_WritePin      ( ARD_SPI_NSS_GPIO_Port, ARD_SPI_NSS_Pin, GPIO_PIN_SET);

USE SPI3 connected to STMOD2

HAL_GPIO_WritePin      ( STMOD2_SPI_NSS_GPIO_Port, STMOD2_SPI_NSS_Pin, GPIO_PIN_RESET);
HAL_SPI_TransmitReceive(&STMOD2_SPI, tx_data_1, rx_data_1,DATA_SIZE_1, 0xFFFFFFFF);
HAL_GPIO_WritePin      ( STMOD2_SPI_NSS_GPIO_Port, STMOD2_SPI_NSS_Pin, GPIO_PIN_SET);
