STM32 Timer Application Notes-EEWORLD

Collect

As we all know, the timer functions of STM32 are very large and complex, and their applications are also very common. Currently, the STM32 family has 10 product lines, all of which have multiple built-in timer peripherals. Although the timers of each STM32 series may differ slightly in number and characteristics, they still have some common features and the same operating mode as a whole.

ST has an official application note for STM32 general-purpose timers, numbered AN4776, which is quite detailed and rich in content. This note mainly describes the basic characteristics, operation modes and related applications of STM32 general-purpose timers in detail and clearly. It not only explains the basic concepts in detail, but also introduces the principles of related practical applications, and also comes with reference engineering codes for related applications. This note is worth reading.

Here is a brief introduction to the basic content framework of the AN4776 application note.

This note is mainly divided into two parts. The first part mainly describes and explains the basic composition and characteristics of the STM32 timer. The second part specifically describes some specific applications of the STM32 timer, including the introduction of the basic working principle and related application code.

The first part includes the following contents:

1.1 Basic components of STM32 timer

Master-slave control unit

Time base unit

Timer channel unit

Brake unit

1.2 Basic working mode of STM32 timer

Timer basic function configuration

Channel configuration for input mode

Channel configuration for output mode

1.3 STM32 timer clock and timing

Synchronous function module

External clock source mode 1

External clock source mode 2

Comparison between external clock source mode 1 and mode 2

The second part of the specific application introduction includes the following contents:

2.1 Use single pulse mode to achieve the output of a specified number of pulses

twenty one
2.2 Using brake input to achieve cycle-by-cycle adjustment function

twenty two

2.3 Using the timer's DMA burst transfer to output arbitrary waveforms

twenty three

2.4 Using the synchronization characteristics of the timer to periodically output a specified number of pulses

twenty four

STM32 learning: the three main parts of STM32F4XX

Three major modules: power supply, IO port and clock. 1. First, let's take a look at the power supply. Here is the power supply block diagram From the above we can see that the power supply provides power to three key parts inside. The first is to power the ADC, which needs no further explanation. The second is the ba

STM32 study notes 5: general timer PWM output

1. Basic concepts of TIMER output PWM Pulse Width Modulation (PWM), short for "Pulse Width Modulation", is a very effective technology that uses the digital output of a microprocessor to control analog circuits. To put it simply, it is the control of pulse width. It is generally used to control the speed of a ste

STM32 interrupt priority setting

The STM32 manual does not mention the setting of interrupt priority, but only lists the interrupt vector table. Based on the vector table, an enumeration data of the interrupt number can be created to facilitate the use of setting priority and enabling. Let me first talk about how to set priorities. The priority s

STM32 - Hardware IIC slave communication

Preface: 　　According to the information on the Internet, most netizens said that there is a bug in the hardware IIC of STM32, which is easy to get stuck when reading and writing. I also got stuck when debugging, but I finally debugged it bit by bit and it worked. This article will record some of my experience in debug
