17.EEPROM (IIC bus)
Composition and working principle of IIC serial bus The use of serial bus technology can greatly simplify the hardware design of the system, reduce the size of the system, and improve reliability. At the same time, the system can be easily modified and expanded. Commonly used serial expansion buses include: IIC (Int

The interrupt response process of 80c51 microcontroller
Interrupt Response Interrupt response is the acceptance of the interrupt request from the interrupt source by the single-chip CPU. After the interrupt request is responded, it goes through a series of operations and then turns to the interrupt service routine to complete the processing task required by the int

How to perform serial communication between two 80c51 microcontrollers
I used to think that serial communication can only be done between a microcontroller and a PC. Yesterday, I accidentally saw a program that can be used to communicate between microcontrollers. This little thing is really amazing! I spent a long time trying to figure it out yesterday, but today, with the help of a gr

Standard 80C51 MCU emulates I2C bus host program
I2C bus protocol program When I was making the program, I found Zhou Ligong's program on the Internet. I felt it was pretty good, so I reposted it. When using it, you must pay attention to the issues of sequence and time. "i2c.h file" //I2C bus integrated sending function, sending multiple bytes of data to the slave
