采用stm32单片机作为控制核心，使用rs485风速传感器和rs485风向传感器采集风速和风向信息，并通过OLED显示屏将结果显示出来。给出代码

以下是一个简单的stm32单片机控制代码示例，用于读取rs485风速传感器和rs485风向传感器的数据，并在OLED显示屏上显示结果。请注意，以下代码仅供参考，具体实现需要根据实际情况进行修改：

#include "stm32f10x.h"
#include "stm32f10x_usart.h"
#include "stm32f10x_gpio.h"
#include "stm32f10x_rcc.h"
#include "stm32f10x_spi.h"

uint8_t uart_rx_pos = 0;

void USART1_IRQHandler(void)
{
    if (USART_GetITStatus(USART1, USART_IT_RXNE) != RESET)
    {
        char ch = USART_ReceiveData(USART1);
        if (uart_rx_pos < UART_RX_BUF_SIZE)
        {
            uart_rx_buf[uart_rx_pos++] = ch;
        }
    }
}

{
    GPIO_InitTypeDef GPIO_InitStructure;
    USART_InitTypeDef USART_InitStructure;
    NVIC_InitTypeDef NVIC_InitStructure;

    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_AFIO, ENABLE);
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_USART1, ENABLE);

    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_10;

    NVIC_Init(&NVIC_InitStructure);

    USART_ITConfig(USART1, USART_IT_RXNE, ENABLE);
    USART_Cmd(USART1, ENABLE);
}

void USART1_SendString(char *str)
{
    while (*str)
    {
        USART_SendData(USART1, *str++);
        while (USART_GetFlagStatus(USART1, USART_FLAG_TC) == RESET);
    }
}

void RS485_SendData(uint8_t *data, uint8_t len)
{
    GPIO_SetBits(GPIOA, GPIO_Pin_12);
    for (int i = 0; i < len; i++)
    {
        USART_SendData(USART1, data[i]);
        while (USART_GetFlagStatus(USART1, USART_FLAG_TC) == RESET);
    }

}

void RS485_RecvData(uint8_t *data, uint8_t len)
{
    uart_rx_pos = 0;
    while (uart_rx_pos < len)
    {
        delay_us(10);
    }
    memcpy(data, uart_rx_buf, len);
}

void delay_us(uint32_t us)
{
    uint32_t start = SysTick->VAL;
    uint32_t ticks = us * (SystemCoreClock / 1000000);
    while ((SysTick->VAL - start) < ticks);
}

int main(void)
{
    SysTick_Config(SystemCoreClock / 1000000);

    USART1_Init();
    OLED_Init();

    while (1)
    {
        uint8_t wind_speed_data[4];
        uint8_t wind_direction_data[4];

        // 读取风速数据
        uint8_t wind_speed_cmd[] = {0x01, 0x03, 0x00, 0x00, 0x00, 0x01, 0x84, 0x0A};
        RS485_SendData(wind_speed_cmd, 8);
        RS485_RecvData(wind_speed_data, 4);
        uint16_t wind_speed = (wind_speed_data[0] << 8) | wind_speed_data[1];

        // 读取风向数据
        uint8_t wind_direction_cmd[] = {0x01, 0x03, 0x00, 0x02, 0x00, 0x01, 0xC5, 0xCA};
        RS485_SendData(wind_direction_cmd, 8);
        RS485_RecvData(wind_direction_data, 4);
        uint16_t wind_direction = (wind_direction_data[0] << 8) | wind_direction_data[1];

        // 在OLED显示屏上显示结果
        OLED_Clear();
        OLED_ShowString(0, 0, "Wind Speed:");
        OLED_ShowNum(0, 2, wind_speed, 5, 16);
        OLED_ShowString(0, 4, "Wind Direction:");
        OLED_ShowNum(0, 6, wind_direction, 5, 16);
        delay_us(1000000);
    }
}

在以上代码中，我们将USART1配置为RS485通信模式，并使用OLED显示屏显示风速和风向信息。在RS485通信中，我们通过发送命令字节并接收回复字节来读取传感器数据。在USART1_IRQHandler()中，我们将接收到的数据存储在uart_rx_buf中，并在RS485_RecvData()函数中使用memcpy()将其复制到数据缓冲区中。

请注意，以上代码仅供参考，实际实现需要根据实际情况进行修改和调整。
