stm32f103c8t6驱动tm1638

要驱动TM1638，您需要使用STM32F103C8T6的GPIO和SPI接口。首先，您需要将TM1638的CLK、STB和DIO引脚连接到STM32F103C8T6的GPIO引脚上，然后将TM1638的CS引脚连接到STM32F103C8T6的SPI CS引脚上。接下来，您需要编写STM32的代码来控制TM1638。

以下是一个简单的代码示例：

#include "stm32f10x.h"

void TM1638_Init(void)
{
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA, ENABLE);
    RCC_APB2PeriphClockCmd(RCC_APB2Periph_SPI1, ENABLE);

    GPIO_InitTypeDef GPIO_InitStructure;

    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_7 | GPIO_Pin_6 | GPIO_Pin_5;
    GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    GPIO_InitStructure.GPIO_Pin = GPIO_Pin_4;
    GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;
    GPIO_Init(GPIOA, &GPIO_InitStructure);

    SPI_InitTypeDef SPI_InitStructure;

    SPI_InitStructure.SPI_Direction = SPI_Direction_1Line_Tx;
    SPI_InitStructure.SPI_Mode = SPI_Mode_Master;
    SPI_InitStructure.SPI_DataSize = SPI_DataSize_8b;
    SPI_InitStructure.SPI_CPOL = SPI_CPOL_Low;
    SPI_InitStructure.SPI_CPHA = SPI_CPHA_1Edge;
    SPI_InitStructure.SPI_NSS = SPI_NSS_Soft;
    SPI_InitStructure.SPI_BaudRatePrescaler = SPI_BaudRatePrescaler_4;
    SPI_InitStructure.SPI_FirstBit = SPI_FirstBit_MSB;
    SPI_Init(SPI1, &SPI_InitStructure);

    SPI_Cmd(SPI1, ENABLE);

    TM1638_SendCommand(0x8F);
    TM1638_SendCommand(0x40);
    TM1638_SendCommand(0xC0);
}

void TM1638_SendCommand(uint8_t command)
{
    GPIO_ResetBits(GPIOA, GPIO_Pin_4);
    SPI_I2S_SendData(SPI1, command);
    while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_TXE) == RESET);
    while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_RXNE) == RESET);
    while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_BSY) == SET);
    GPIO_SetBits(GPIOA, GPIO_Pin_4);
}

void TM1638_SendData(uint8_t address, uint8_t data)
{
    TM1638_SendCommand(0x44);
    GPIO_ResetBits(GPIOA, GPIO_Pin_4);
    SPI_I2S_SendData(SPI1, 0xC0 | address);
    while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_TXE) == RESET);
    while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_RXNE) == RESET);
    while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_BSY) == SET);

    SPI_I2S_SendData(SPI1, data);
    while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_TXE) == RESET);
    while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_RXNE) == RESET);
    while (SPI_I2S_GetFlagStatus(SPI1, SPI_I2S_FLAG_BSY) == SET);
    GPIO_SetBits(GPIOA, GPIO_Pin_4);
}

int main(void)
{
    TM1638_Init();

    while (1)
    {
        TM1638_SendData(0x00, 0x01);
        delay_ms(1000);
        TM1638_SendData(0x00, 0x00);
        delay_ms(1000);
    }
}

在这个代码中，TM1638_SendCommand()用于发送TM1638的命令，TM1638_SendData()用于发送TM1638的数据。在main()函数中，我们不停地向TM1638发送数据以使其灯光闪烁。

需要注意的是，本代码只是一个简单的示例，您可能需要根据您的具体情况进行修改。同时，您需要自行实现delay_ms()函数，用于延时。
