Problem : SPI 4, 5 & 6 undeclared in stm32F4xx_spi.c
Posted on April 17, 2013 at 15:38
Hi everyone and thanks in advance for your help.
I'm trying to configure an SPI link between my STM32F4VG407 and a Shift register (M74HC595). I wrote a simple code to start ://#include ''stm32f4xx.h''
#include ''stm32f4xx_gpio.h''
#include ''stm32f4xx_rcc.h''
#include ''stm32f4xx_spi.h''
#define SPI_COMMS SPI1
#define PORT_SPI_COMMS GPIOA
#define PIN_SPI_COMMS_NCS GPIO_Pin_4
#define PIN_SPI_COMMS_SCK GPIO_Pin_5
#define PIN_SPI_COMMS_MISO GPIO_Pin_6
#define PIN_SPI_COMMS_MOSI GPIO_Pin_7
void
RCC_Configuration(
void
);
void
GPIO_Configuration(
void
);
void
SPI_Configuration(
void
);
int
main(
void
)
{
GPIO_Configuration();
SPI_Configuration();
RCC_Configuration();
for
(;;){
SPI_I2S_SendData(SPI1,0xAAAA);
}
}
void
SPI_Configuration(
void
)
{
SPI_InitTypeDef SPI_InitStructure;
/* SPI1 configuration -------------------------------------------------*/
SPI_InitStructure.SPI_Direction = SPI_Direction_2Lines_FullDuplex;
SPI_InitStructure.SPI_Mode = SPI_Mode_Master;
SPI_InitStructure.SPI_DataSize = SPI_DataSize_8b;
SPI_InitStructure.SPI_CPOL = SPI_CPOL_High;
SPI_InitStructure.SPI_CPHA = SPI_CPHA_2Edge;
SPI_InitStructure.SPI_NSS = SPI_NSS_Hard;
SPI_InitStructure.SPI_BaudRatePrescaler = SPI_BaudRatePrescaler_4;
SPI_InitStructure.SPI_FirstBit = SPI_FirstBit_MSB;
SPI_InitStructure.SPI_CRCPolynomial = 7;
SPI_Init(SPI_COMMS, &SPI_InitStructure);
/* Enable SPI_MASTER TXE interrupt */
SPI_I2S_ITConfig(SPI_COMMS, SPI_I2S_IT_TXE, ENABLE);
/* Enable SPI_MASTER */
SPI_Cmd(SPI_COMMS, ENABLE);
}
void
GPIO_Configuration(
void
)
{
GPIO_InitTypeDef GPIO_InitStructure;
// Enable SPI1 Pins Software Remapping //
//GPIO_PinRemapConfig(GPIO_Remap_SPI1, ENABLE);
// Configure SPI_MASTER pins: SCK,MOSI //
GPIO_InitStructure.GPIO_Pin = PIN_SPI_COMMS_SCK | PIN_SPI_COMMS_MOSI;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_OUT;
GPIO_InitStructure.GPIO_OType = GPIO_OType_PP;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_NOPULL;
GPIO_Init(PORT_SPI_COMMS, &GPIO_InitStructure);
}
void
RCC_Configuration(
void
)
{
// Enable GPIO clock //
RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOA, ENABLE);
}
When I build it, I have the following error :
[cc] D:\Squarp\Code_Ressources\STM32F4xx_StdPeriph_Driver\src\stm32f4xx_spi.c: In function 'SPI_I2S_DeInit':
[cc] D:\Squarp\Code_Ressources\STM32F4xx_StdPeriph_Driver\src\stm32f4xx_spi.c:250:20: error: 'SPI4' undeclared (first use in this function) [cc] D:\Squarp\Code_Ressources\STM32F4xx_StdPeriph_Driver\src\stm32f4xx_spi.c:257:20: error: 'SPI5' undeclared (first use in this function) [cc] D:\Squarp\Code_Ressources\STM32F4xx_StdPeriph_Driver\src\stm32f4xx_spi.c:250:20: note: each undeclared identifier is reported only once for each function it appears in [cc] D:\Squarp\Code_Ressources\STM32F4xx_StdPeriph_Driver\src\stm32f4xx_spi.c:266:17: error: 'SPI6' undeclared (first use in this function) It seems like SPI4, 5 and 6 doesn't exist. I can find only SPI1, SPI2 & SPI3 when I read the datasheet of the STM32F4, so I'm surprised about it. I'm using the ''stm32f4xx_spi.c'' source from ''STM32F4xx_StdPeriph_Driver''. Here is the part of code from ''stm32f4xx_spi.c'' that lead to the failure :/**
* @brief De-initialize the SPIx peripheral registers to their default reset values.
* @param SPIx: To select the SPIx/I2Sx peripheral, where x can be: 1, 2, 3, 4, 5 or 6
* in SPI mode or 2 or 3 in I2S mode.
*
* @note The extended I2S blocks (ie. I2S2ext and I2S3ext blocks) are de-initialized
* when the relative I2S peripheral is de-initialized (the extended block's clock
* is managed by the I2S peripheral clock).
*
* @retval None

void
SPI_I2S_DeInit(SPI_TypeDef* SPIx)
{
/* Check the parameters */
assert_param(IS_SPI_ALL_PERIPH(SPIx));
if
(SPIx == SPI1)

RCC_APB2PeriphResetCmd(RCC_APB2Periph_SPI1, ENABLE);
/* Release SPI1 from reset state */
RCC_APB2PeriphResetCmd(RCC_APB2Periph_SPI1, DISABLE);
}
else
if
(SPIx == SPI2)
{

RCC_APB1PeriphResetCmd(RCC_APB1Periph_SPI2, ENABLE);
/* Release SPI2 from reset state */
RCC_APB1PeriphResetCmd(RCC_APB1Periph_SPI2, DISABLE);
}

{

RCC_APB1PeriphResetCmd(RCC_APB1Periph_SPI3, ENABLE);

RCC_APB1PeriphResetCmd(RCC_APB1Periph_SPI3, DISABLE);
}
else
if
(SPIx == SPI4)
{
/* Enable SPI4 reset state */
RCC_APB2PeriphResetCmd(RCC_APB2Periph_SPI4, ENABLE);
/* Release SPI4 from reset state */
RCC_APB2PeriphResetCmd(RCC_APB2Periph_SPI4, DISABLE);
}
else
if
(SPIx == SPI5)
{
/* Enable SPI5 reset state */
RCC_APB2PeriphResetCmd(RCC_APB2Periph_SPI5, ENABLE);
/* Release SPI5 from reset state */
RCC_APB2PeriphResetCmd(RCC_APB2Periph_SPI5, DISABLE);
}
else
{
if
(SPIx == SPI6)
{
/* Enable SPI6 reset state */
RCC_APB2PeriphResetCmd(RCC_APB2Periph_SPI6, ENABLE);
/* Release SPI6 from reset state */
RCC_APB2PeriphResetCmd(RCC_APB2Periph_SPI6, DISABLE);
}
}
I tried to comment the concerned part and it does build properly but I have the feeling that it's not a good thing to do.
Do someone know something about my issue? Thanks again.
