Introduction to general timer 2. Timer initialization function 3. PWM wave ---------------------— I Introduction of timer ------- 1. What is a universal timer? ...

preface This section will summarize STM32 (V) Each IO of STM32 can be used as an interrupt input port for external interrupts, which is also the strength of STM32. The interrupt controller of STM32F103 supports 19 external interrupt / event requests. Each interrupt has a status Bit, each interrupt / event has independent trigger and mask set ...

brief introduction target Translation and supplement open62541v1 2 official manual. Information model callback There are three places where callbacks from the information model to user-defined code can occur. Custom node constructors and destructorsLinking VariableNodes to external data sourcesMethod node callback void UA_Server_ ...

brief introduction The client implementation allows remote access to all OPC UA services. For convenience, some functions have been wrapped in Advanced abstraction Yes. However, at present, the client does not contain its own thread or event driven main loop, which means that the client will not automatically perform any action in the bac ...

brief introduction When writing an application, it is more comfortable to use some GUI tools to create an information model. Most tools can export data according to OPC UA Nodeset XML schema. open62541 includes a python based nodeset compiler, which can transform these information model definitions into a working server. Note that you can ...

LCD driver based on FrameBuffer frame of STM32MP157 What is FrameBuffer? Framebuffer is translated into Chinese, that is, frame buffer. Frame is the smallest unit in image animation. A frame is a still picture, and continuous frames form animation. Then frame buffer is used to cache the data of a frame. In the linux kernel, it is a program in ...

First, the concept of IIC is omitted. It's written in detail on the Internet. Let's start with the CUBEMX configuration code. The project in hand is a host and seven slaves. The slave uses the middle transceiver. The address is a big pit, and the subsequent read-write interrupt is also a pit. Slave address: The hardware is I2C_ ADDRESSINGMODE ...

summary The title of all the work to be done in this paper basically includes reading the temperature value of the temperature sensor, and then printing it to the serial assistant through the serial port; A lot of bloggers' great God's tutorial I always follow the steps to make the program do not report errors and detect the sensor's condition ...
