C51 programming experience summary sharing

　　In the development and application of microcontrollers, high-level languages have gradually begun to be introduced, and C language is one of them. People who are used to assembly always feel that high-level languages are not as "controllable" as they can be as arbitrary as assembly. The following are some of the

C51 writes serial communication, simulation and debugging in proteus————The ultimate nanny-level teaching

Two communication methods Serial Communication: Serial communication is the process of dividing data bytes into bits. Parallel communication: Parallel communication usually involves transmitting each bit of a data byte simultaneously using multiple data lines. Serial communication is divided into two types Synchrono

Several useful modules for C51 programming - keyboard scanning module

The keyboard scanning module has two working modes, one is automatically called by the clock module, and the other is called by the programmer. 1) Automatically called by the clock module Include the clock module implementation file (Timer.h) and the keyboard scanning module implementation file (KBScan.c) into the

"Beginner's C51 Self-study Notes" - Four working modes of timer (Part 2)

1. Method 0: Mode 0 is a 13-bit count, consisting of the lower 5 bits of TL0 (the upper 3 bits are unused) and the 8 bits of TH0. When the lower 5 bits of TL0 overflow, they carry to TH0. When TH0 overflows, the TF0 flag in TCON is set and an interrupt request is sent to the CPU. There are 13 bits in total. The 3

Development board schematic diagram: From the schematic diagram of the development board, we know that LEDs 1 to 8 are connected to P2＾0 to P2＾7 respectively. When low voltage is input to P2 port, the LED lights up (VCC indicates high voltage, and P2 outputs low voltage when it is 0 and high voltage when it is 1). I

【C51】Introduction to MCU Timer

The standard 51 architecture microcontroller has two timers: T0 and T1. Their usage is almost the same. The following mainly describes the usage of T0 timer. Initial understanding The timer and counter are the same module in the microcontroller. Their essence is: addition storage counter. The counter is easy to un
