PIN_STAT_SET是什么

PIN_STAT_SET是Pin Tool中的一个函数，用于设置针脚（pin）的统计信息。该函数的参数是一个结构体，用于指定需要设置的统计信息的类型和值。例如，可以使用该函数来记录某个指令被执行的次数、某个内存地址被读取或写入的次数等等。

在使用该函数之前，需要先调用PIN_AddThreadStartFunction和PIN_AddFiniFunction等函数来注册一些回调函数，以便在程序执行过程中进行一些操作，例如记录统计信息。同时还需要在main函数中调用PIN_Init(argc, argv)来初始化Pin工具，并指定要运行的二进制程序。

写一个详细的stm32F103RC与ADS129X通过SPI通信的代码

好的，下面是一个详细的STM32F103RC与ADS129X通过SPI通信的代码。在此之前，需要先了解ADS129X芯片的寄存器及其功能，以及SPI通信的基本原理。

首先在STM32F103RC上配置SPI总线，以控制ADS129X芯片的通信。

#include "stm32f10x.h"

// SPI总线初始化函数
void SPI_Configuration(void)
{
    SPI_InitTypeDef SPI_InitStructure;
    GPIO_InitTypeDef GPIO_InitStructure;

    // 开启SPI1时钟
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_SPI1, ENABLE);

    // 开启GPIOA时钟
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);

    // PA5--SCK, PA6--MISO, PA7--MOSI
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_5 | GPIO_Pin_6 | GPIO_Pin_7; 
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    // CS引脚
    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_4;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    // SPI参数配置
    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_Soft;
    SPI_InitStructure.SPI_BaudRatePrescaler = SPI_BaudRatePrescaler_16;
    SPI_InitStructure.SPI_FirstBit = SPI_FirstBit_MSB;
    SPI_InitStructure.SPI_CRCPolynomial = 7;
    SPI_Init(SPI1, &SPI_InitStructure);

    // 使能SPI总线
    SPI_Cmd(SPI1, ENABLE);
}

接下来，通过SPI总线完成ADS129X芯片的初始化。

// ADS129X初始化函数
void ADS129X_Init(void)
{
    // 硬件复位ADS129X
    GPIO_ResetBits(GPIOA, GPIO_Pin_4);
    delay_ms(100);
    GPIO_SetBits(GPIOA, GPIO_Pin_4);
    delay_ms(100);

    // 读取ID寄存器，确认芯片正常
    uint8_t id = ADS129X_ReadReg(ADS129X_ID);
    if (id != ADS129X_ID_VALUE)
    {
        // ID寄存器读取错误，芯片异常
        return;
    }

    // 设置配置寄存器
    ADS129X_WriteReg(ADS129X_CONFIG1, ADS129X_CONFIG1_VALUE);
    ADS129X_WriteReg(ADS129X_CONFIG2, ADS129X_CONFIG2_VALUE);
    ADS129X_WriteReg(ADS129X_LOFF, ADS129X_LOFF_VALUE);
    ADS129X_WriteReg(ADS129X_CH1SET, ADS129X_CH1SET_VALUE);
    ADS129X_WriteReg(ADS129X_CH2SET, ADS129X_CH2SET_VALUE);
    ADS129X_WriteReg(ADS129X_RLD_SENS, ADS129X_RLD_SENS_VALUE);
    ADS129X_WriteReg(ADS129X_LOFF_SENS, ADS129X_LOFF_SENS_VALUE);
    ADS129X_WriteReg(ADS129X_LOFF_STAT, ADS129X_LOFF_STAT_VALUE);
    ADS129X_WriteReg(ADS129X_RESP1, ADS129X_RESP1_VALUE);
    ADS129X_WriteReg(ADS129X_RESP2, ADS129X_RESP2_VALUE);
    ADS129X_WriteReg(ADS129X_GPIO, ADS129X_GPIO_VALUE);
    ADS129X_WriteReg(ADS129X_PACE, ADS129X_PACE_VALUE);
    ADS129X_WriteReg(ADS129X_CFG_CAL, ADS129X_CFG_CAL_VALUE);
    ADS129X_WriteReg(ADS129X_MISC1, ADS129X_MISC1_VALUE);
    ADS129X_WriteReg(ADS129X_MISC2, ADS129X_MISC2_VALUE);
    ADS129X_WriteReg(ADS129X_CONFIG3, ADS129X_CONFIG3_VALUE);
    ADS129X_WriteReg(ADS129X_CH3SET, ADS129X_CH3SET_VALUE);
    ADS129X_WriteReg(ADS129X_CH4SET, ADS129X_CH4SET_VALUE);
    ADS129X_WriteReg(ADS129X_RESP3, ADS129X_RESP3_VALUE);
    ADS129X_WriteReg(ADS129X_PACE2, ADS129X_PACE2_VALUE);
    ADS129X_WriteReg(ADS129X_LOFF_SENS2, ADS129X_LOFF_SENS2_VALUE);
    ADS129X_WriteReg(ADS129X_STAT, ADS129X_STAT_VALUE);
    ADS129X_WriteReg(ADS129X_CH5SET, ADS129X_CH5SET_VALUE);
    ADS129X_WriteReg(ADS129X_CH6SET, ADS129X_CH6SET_VALUE);
    ADS129X_WriteReg(ADS129X_LOFF_STAT2, ADS129X_LOFF_STAT2_VALUE);
    ADS129X_WriteReg(ADS129X_MUX, ADS129X_MUX_VALUE);
    ADS129X_WriteReg(ADS129X_CH7SET, ADS129X_CH7SET_VALUE);
    ADS129X_WriteReg(ADS129X_CH8SET, ADS129X_CH8SET_VALUE);
    ADS129X_WriteReg(ADS129X_CFG_EMG, ADS129X_CFG_EMG_VALUE);

    // 启动ADS129X
    ADS129X_WriteReg(ADS129X_CONFIG1, ADS129X_CONFIG1_VALUE | ADS129X_CONFIG1_START);
}

其中，ADS129X_ReadReg和ADS129X_WriteReg函数用于读取和写入ADS129X的寄存器。

// 读取ADS129X的寄存器
uint8_t ADS129X_ReadReg(uint8_t reg)
{
    uint8_t value;

    // 使能ADS129X
    GPIO_ResetBits(GPIOA, GPIO_Pin_4);

    // 发送读取命令和寄存器地址
    SPI_I2S_SendData(SPI1, ADS129X_CMD_RREG | reg);
    while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_BSY) == SET);
    SPI_I2S_SendData(SPI1, 0x00);
    while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_BSY) == SET);

    // 接收寄存器值
    SPI_I2S_SendData(SPI1, 0x00);
    while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_BSY) == SET);
    value = SPI_I2S_ReceiveData(SPI1);

    // 禁用ADS129X
    GPIO_SetBits(GPIOA, GPIO_Pin_4);

    return value;
}

// 写入ADS129X的寄存器
void ADS129X_WriteReg(uint8_t reg, uint8_t value)
{
    // 使能ADS129X
    GPIO_ResetBits(GPIOA, GPIO_Pin_4);

    // 发送写入命令和寄存器地址
    SPI_I2S_SendData(SPI1, ADS129X_CMD_WREG | reg);
    while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_BSY) == SET);

    // 发送数据
    SPI_I2S_SendData(SPI1, value);
    while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_BSY) == SET);

    // 禁用ADS129X
    GPIO_SetBits(GPIOA, GPIO_Pin_4);
}

最后，可以通过ADS129X_ReadData函数读取ADS129X采集的数据。

// 读取ADS129X采集的数据
void ADS129X_ReadData(uint8_t *data, uint32_t size)
{
    // 使能ADS129X
    GPIO_ResetBits(GPIOA, GPIO_Pin_4);

    // 发送读取命令
    SPI_I2S_SendData(SPI1, ADS129X_CMD_RDATA);
    while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_BSY) == SET);

    // 接收数据
    for (uint32_t i = 0; i < size; i++)
    {
        SPI_I2S_SendData(SPI1, 0x00);
        while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_BSY) == SET);
        data[i] = SPI_I2S_ReceiveData(SPI1);
    }

    // 禁用ADS129X
    GPIO_SetBits(GPIOA, GPIO_Pin_4);
}

以上是一个简单的STM32F103RC与ADS129X通过SPI通信的代码，仅供参考。实际应用中，还需要根据具体需求进行完善和修改。

GD32f103串口通信代码

以下是一个简单的GD32F103串口通信的示例代码：

#include "gd32f10x.h"
#include <stdio.h>

void usart_config(void);
void usart_gpio_config(void);
int fputc(int ch, FILE *f);

int main(void)
{
    /* 配置串口 */
    usart_config();
    
    /* 发送数据 */
    printf("Hello, world!\r\n");
    
    while(1)
    {
        /* 接收数据并处理 */
        if(USART0_STAT(USART0) & USART_STAT_RBNE)
        {
            uint8_t data = USART0_DATA(USART0);
            /* 处理接收到的数据 */
        }
    }
    
    return 0;
}

/* 配置串口参数 */
void usart_config(void)
{
    /* 使能串口时钟 */
    rcu_periph_clock_enable(RCU_USART0);
    
    /* 配置串口引脚 */
    usart_gpio_config();
    
    /* 配置串口参数 */
    usart_deinit(USART0);
    usart_baudrate_set(USART0, 115200U);
    usart_word_length_set(USART0, USART_WL_8BIT);
    usart_stop_bit_set(USART0, USART_STB_1BIT);
    usart_parity_config(USART0, USART_PM_NONE);
    usart_hardware_flow_rts_config(USART0, USART_RTS_DISABLE);
    usart_hardware_flow_cts_config(USART0, USART_CTS_DISABLE);
    usart_receive_config(USART0, USART_RECEIVE_ENABLE);
    usart_transmit_config(USART0, USART_TRANSMIT_ENABLE);
    
    /* 使能串口 */
    usart_enable(USART0);
}

/* 配置串口引脚 */
void usart_gpio_config(void)
{
    /* 使能GPIOA时钟 */
    rcu_periph_clock_enable(RCU_GPIOA);
    
    /* 配置PA9为USART0输出引脚 */
    gpio_init(GPIOA, GPIO_MODE_AF_PP, GPIO_OSPEED_50MHZ, GPIO_PIN_9);
    
    /* 配置PA10为USART0输入引脚 */
    gpio_init(GPIOA, GPIO_MODE_IN_FLOATING, GPIO_OSPEED_50MHZ, GPIO_PIN_10);
}

/* 重定向printf函数，用于串口输出 */
int fputc(int ch, FILE *f)
{
    usart_data_transmit(USART0, (uint8_t)ch);
    while(RESET == usart_flag_get(USART0, USART_FLAG_TBE));
    
    return ch;
}

这是一个简单的串口通信示例，使用的是USART0和GPIOA的引脚。你可以根据需要修改引脚和串口的配置参数。在主函数中，首先调用`usart_config()`函数配置串口，然后使用`printf()`函数向串口发送数据。在接收数据的部分，通过检查`USART0_STAT(USART0) & USART_STAT_RBNE`来判断是否接收到数据，然后使用`USART0_DATA(USART0)`读取接收到的数据。你可以根据你的需求在接收到数据后进行相应的处理。

请注意，以上代码仅为示例，实际应用中还需要进行错误处理和其他必要的配置。
