Using CH32V103 to drive TM1637 four-digit digital tube module [Copy link]

 

I refer to the official example and use CH32V103 to drive TM1637 digital tube successfully. The code is very simple. I hope you guys don't criticize me.
TM1637.h:

#define  TM1637_DIO_L  GPIO_ResetBits(GPIOA,GPIO_Pin_1)  //配置SDA接口低电平

#define  TM1637_CLK_H  GPIO_SetBits(GPIOA,GPIO_Pin_2)    //配置SCL接口高电平
#define  TM1637_CLK_L  GPIO_ResetBits(GPIOA,GPIO_Pin_2)  //配置SCL接口低电平

#define  TM1637_SDA_READ()  GPIO_ReadInputDataBit(GPIOA, GPIO_Pin_1)  //读SDA口线状态

What does the TM1637 digital tube look like?

It should be programmed with TM1637 to drive the digital tube

Oh, it should be a module.
