请写一下stm32f103c8t6读取max6675温度的程序其中max6675芯片sck引脚与Pa5相连so引脚与Pa6相连cs引脚与Pb6相连

以下是STM32F103C8T6读取MAX6675温度的程序：

#include "stm32f10x.h"

#define CS_GPIO GPIOB
#define CS_PIN GPIO_Pin_6

SPI_InitTypeDef SPI_InitStruct;

void SPI_Configuration(void)
{
    GPIO_InitTypeDef GPIO_InitStructure;

    /* Enable peripheral clocks --------------------------------------------------*/
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_GPIOB | RCC_APB2Periph_SPI1, ENABLE);

    /* Configure SPI1 pins: SCK and MOSI ---------------------------------------*/
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_5 | GPIO_Pin_7;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    /* Configure SPI1 pins: MISO -----------------------------------------------*/
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_6;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_IN_FLOATING;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    /* Configure CS pin ---------------------------------------------------------*/
    GPIO_InitStructure.GPIO_Pin = CS_PIN;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(CS_GPIO, &GPIO_InitStructure);

    /* Configure SPI1 ------------------------------------------------------------*/
    SPI_StructInit(&SPI_InitStruct);
    SPI_InitStruct.SPI_Direction = SPI_Direction_2Lines_FullDuplex;
    SPI_InitStruct.SPI_Mode = SPI_Mode_Master;
    SPI_InitStruct.SPI_DataSize = SPI_DataSize_16b;
    SPI_InitStruct.SPI_CPOL = SPI_CPOL_High;
    SPI_InitStruct.SPI_CPHA = SPI_CPHA_2Edge;
    SPI_InitStruct.SPI_NSS = SPI_NSS_Soft;
    SPI_InitStruct.SPI_BaudRatePrescaler = SPI_BaudRatePrescaler_256;
    SPI_InitStruct.SPI_FirstBit = SPI_FirstBit_MSB;
    SPI_Init(SPI1, &SPI_InitStruct);

    /* Enable SPI1 */
    SPI_Cmd(SPI1, ENABLE);
}

uint16_t MAX6675_Read(void)
{
    uint16_t data;

    /* Set CS pin low */
    GPIO_ResetBits(CS_GPIO, CS_PIN);

    /* Send dummy data to initiate read */
    SPI_I2S_SendData(SPI1, 0x0000);

    /* Wait for data to be received */
    while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_RXNE) == RESET);

    /* Read received data */
    data = SPI_I2S_ReceiveData(SPI1);

    /* Set CS pin high */
    GPIO_SetBits(CS_GPIO, CS_PIN);

    return data;
}

int main(void)
{
    uint16_t max6675_data = 0;
    float temperature = 0;

    /* Configure SPI */
    SPI_Configuration();

    while (1)
    {
        /* Read MAX6675 */
        max6675_data = MAX6675_Read();

        /* Convert MAX6675 data to temperature */
        temperature = ((max6675_data >> 3) * 0.25);

        /* Do something with temperature */
        // ...

        /* Delay */
        for (int i = 0; i < 1000000; i++);
    }
}

在主函数中，我们首先调用SPI_Configuration()函数来配置SPI接口。在SPI_Configuration()函数中，我们使用GPIO_InitTypeDef和SPI_InitTypeDef结构体来配置SPI接口和相关GPIO引脚。我们将SCK和MOSI引脚配置为复用推挽输出，并将MISO引脚配置为浮空输入。CS引脚配置为推挽输出。我们将SPI接口配置为主模式，16位数据大小，极性为高，相位为2边沿，软件NSS控制，波特率分频为256，MSB优先。最后，我们启用SPI接口。

在主循环中，我们使用MAX6675_Read()函数来读取MAX6675芯片的温度数据。我们将读取到的16位数据向右移动3位，然后乘以0.25来得到温度值。最后，我们可以使用温度值来执行一些操作。在循环末尾，我们添加一个简单的延时以避免读取MAX6675的速度过快
