帮我写一份STM32代码，用来控制Max529

好的，以下是一份基础的STM32代码，用于控制Max529：

#include "stm32f10x.h"

#define MAX529_CS_PIN GPIO_Pin_4
#define MAX529_CS_PORT GPIOA

void MAX529_Init(void);
void MAX529_Write(uint16_t data);

int main(void)
{
    MAX529_Init();

    while(1)
    {
        // 在这里编写你的代码
        // 控制Max529
    }
}

void MAX529_Init(void)
{
    GPIO_InitTypeDef GPIO_InitStruct;
    SPI_InitTypeDef SPI_InitStruct;

    // 使能SPI和GPIO时钟
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_SPI1 | RCC_APB2Periph_GPIOA, ENABLE);

    // 配置SPI引脚
    GPIO_InitStruct.GPIO_Pin = GPIO_Pin_5 | GPIO_Pin_6 | GPIO_Pin_7;
    GPIO_InitStruct.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_InitStruct.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOA, &GPIO_InitStruct);

    // 配置CS引脚
    GPIO_InitStruct.GPIO_Pin = MAX529_CS_PIN;
    GPIO_InitStruct.GPIO_Mode = GPIO_Mode_Out_PP;
    GPIO_InitStruct.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(MAX529_CS_PORT, &GPIO_InitStruct);

    // 配置SPI
    SPI_InitStruct.SPI_Direction = SPI_Direction_1Line_Tx;
    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);

    SPI_Cmd(SPI1, ENABLE);
}

void MAX529_Write(uint16_t data)
{
    GPIO_ResetBits(MAX529_CS_PORT, MAX529_CS_PIN);
    SPI_I2S_SendData(SPI1, data);
    while(SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_BSY) == SET);
    GPIO_SetBits(MAX529_CS_PORT, MAX529_CS_PIN);
}

这份代码使用SPI通信协议来控制Max529，其中MAX529_CS_PIN和MAX529_CS_PORT为你连接Max529的CS引脚所对应的GPIO引脚号和端口号。你需要在main函数中编写你的代码，来根据你的实际需求控制Max529的输出。
