In response to the request of netizens, a program written in C language is written below. In the circuit, three buttons are used, and two digital displays are used. Either 12MHz or 11.0592MHz crystal...[Details]

Let's connect an LED to the MCU minimum system and see if we can light it up! By the way, the MCU minimum system has been mentioned several times above. The so-called MCU minimum system is to connect...[Details]

1. Program optimization Modify Makefile Copy the mmu code in main.c to mmu.c and modify it as follows Modification of main.c Since MMU is gener...[Details]

After countless inquiries and queries, I finally figured out the FLASH problem. It turns out that no matter whether the FLASH of the microcontroller is paged or not, the program is written on the FLAS...[Details]

Thermistors are generally used as sensors to measure temperature. The measurement methods include R-V conversion voltage measurement method and R-F conversion frequency measurement method. The circuit...[Details]

1. MCU interrupt: I used Baidu to find a picture of the 80C51 microcontroller as follows: Among them, at the position of P3.2 and P3.3, that is, at pins 12 and 13, there are INT0 and INT1, which...[Details]

When we talk about exception vectors, we will think of interrupt vectors. In fact, interrupts are a subset of exceptions, which means that interrupts are actually a type of exception. Back to the e...[Details]

The clock management module uniformly manages the chip clock input, clock generation and control, including: the clock management module has the following two parts of input: ...[Details]

In general ARM programming teaching and experimental environments, the development environment of ADS plus parallel port to Jtag board + H-Jtag is generally used. But the biggest disadvantage of this...[Details]

#include #include delays.h #include timers.h   typedef unsigned int  uint; typedef unsigned char uchar; typedef unsigned long ulong;   // 4-bit digital tube position value register def...[Details]

   The digital tube dynamically and vaguely displays the numbers 1-2-3-4-5-6-7-8. The so-called dynamic display actually means that the digital tube scans continuously. We assign values ​​to the firs...[Details]

1.  Introduction to BootLoader Running GNU/Linux systems on dedicated embedded boards has become increasingly popular. From a software perspective, an embedded Linux system can usually be divided i...[Details]

1. Light up the conjecture at the same time In the first section of this chapter, we said that if we want to light up the digital tube, then the small LED light we learned in the first chapter will...[Details]

 This is the PWM output mode of STM32. The TIM1 module of STM32 is an enhanced timer module, which is born for motor control. It can generate 3 groups of 6 PWMs. At the same time, each group of 2 PWMs...[Details]

O Introduction At present, most of the lighting systems in large spaces such as squares or classrooms adopt a full lighting method. Even if there are people in a certain area, all lighting...[Details]
