Where can I download the library "stm32f3xx_spi.h" and "stm32f3xx_gpio.h" ?

[Peter BENSCH]

Either you mean the header files

• stm32f30x_spi.h
• stm32f30x_gpio.h

which are in the SPL (Standard Peripheral Library) for STM32F30x and STM32F334 (STSW-STM32108),

or you mean

• stm32f3xx_hal_spi.h
• stm32f3xx_hal_gpio.h

from the Cube firmware for the STM32F3 family.

Where is the source code to be found that wants these header files?

I mean stm32f30x_spi.h and stm32f30x_gpio.h ,.

Here's a feature of my code to exemplify what I want

void SPI_Init(void)

{

 SPI_InitTypeDef SPI_InitStruct;

 GPIO_InitTypeDef GPIO_InitStruct;

 // Enable clock for SPI1 and GPIOA

 RCC_APB2PeriphClockCmd(RCC_APB2Periph_SPI1, ENABLE);

 RCC_AHBPeriphClockCmd(RCC_AHBPeriph_GPIOA, ENABLE);

 // Configure SPI1 pins: SCK, MISO, MOSI

 GPIO_InitStruct.GPIO_Pin = GPIO_Pin_5 | GPIO_Pin_6 | GPIO_Pin_7;

 GPIO_InitStruct.GPIO_Mode = GPIO_Mode_AF;

 GPIO_InitStruct.GPIO_Speed = GPIO_Speed_50MHz;

 GPIO_InitStruct.GPIO_OType = GPIO_OType_PP;

 GPIO_InitStruct.GPIO_PuPd = GPIO_PuPd_NOPULL;

 GPIO_Init(GPIOA, &GPIO_InitStruct);

 // Connect SPI1 pins to SPI alternate function

 GPIO_PinAFConfig(GPIOA, GPIO_PinSource5, GPIO_AF_5);

 GPIO_PinAFConfig(GPIOA, GPIO_PinSource6, GPIO_AF_5);

 GPIO_PinAFConfig(GPIOA, GPIO_PinSource7, GPIO_AF_5);

 // Configure chip select pin for L3GD20

 GPIO_InitStruct.GPIO_Pin = L3GD20_CS_PIN;

 GPIO_InitStruct.GPIO_Mode = GPIO_Mode_OUT;

 GPIO_InitStruct.GPIO_Speed = GPIO_Speed_50MHz;

 GPIO_InitStruct.GPIO_OType = GPIO_OType_PP;

 GPIO_InitStruct.GPIO_PuPd = GPIO_PuPd_UP;

 GPIO_Init(L3GD20_CS_PORT, &GPIO_InitStruct);

 // Set chip select pin high to deselect L3GD20

 GPIO_SetBits(L3GD20_CS_PORT, L3GD20_CS_PIN);

 // Configure SPI1

 SPI_InitStruct.SPI_Direction = SPI_Direction_2Lines_FullDuplex;

 SPI_InitStruct.SPI_Mode = SPI_Mode_Master;

 SPI_InitStruct.SPI_DataSize = SPI_DataSize_8b;

 SPI_InitStruct.SPI_CPOL = SPI_CPOL_Low;

 SPI_InitStruct.SPI_CPHA = SPI_CPHA_1Edge;

 SPI_InitStruct.SPI_NSS = SPI_NSS_Soft;

 SPI_InitStruct.SPI_BaudRatePrescaler = SPI_BaudRatePrescaler_4;

 SPI_InitStruct.SPI_FirstBit = SPI_FirstBit_MSB;

 SPI_InitStruct.SPI_CRCPolynomial = 7;

 SPI_Init(SPI1, &SPI_InitStruct);

 // Enable SPI1

 SPI_Cmd(SPI1, ENABLE);

}

OK, then you can take on the above-mentioned SPL STSW-STM32108.

If the problem is solved, please mark this thread as answered by selecting Select as best, as also explained here. This will help other users find that answer faster.

Good luck!
