catalogue 1. Concepts and definitions 2. Examples When doing embedded development, we often encounter such code: struct { unsigned int widthValidated : 1; unsigned int heightValidated : 1; } status; What does it mean to define structure variables in this way? The main reason is that when some information is stored, it only needs to o ...

brief introduction The main purpose of this paper is to establish the communication connection between STM32 and Dynamixel steering gear, develop the control framework of upper computer lower computer steering gear, issue instructions in the upper computer, the lower computer executes the outer loop of steering gear force control, and the stee ...

preface This program design is based on embedded development board CT117E,stm32f103RBT6. If you don't understand the code of which module, you can click my blog to see the writing ideas of each module. 1, Test questions 2, Modules needed 1.LED The code is as follows: LED c: #include "led.h" void led_init(void) { GPIO_ ...

Program memory allocation The memory occupied by a program compiled by c/C + + is divided into the following parts 1. Stack - automatically allocated and released by the compiler to store the parameter values of functions and the values of local variables. Its operation mode is similar to the stack in the data structure. 2. Heap - generally al ...

Timer classification stm32f1 series, 8 timers, basic timer (TIM6,7), general timer (TIM2,3,4,5) and advanced timer (TIM1,8). Basic timer: a 16 bit timer that can only count up. It can only be timed without external IO General timer: 16 bit timer that can count up / down, timing, output comparison and input capture. Each timer has 4 external ...

Since my work mainly focuses on the network subsystem of the kernel, I just came into contact with this module, so I want to sort out the packet receiving process driven by the network card. The following contents are my personal understanding. If there is anything wrong, I hope you can make more corrections and grow up with each other~ In the ...

shell command The commands that come with the Shell are called built-in commands, which can be implemented through functions inside the Shell. After the Shell is started, the code corresponding to these commands (function body code) is also loaded into memory, so using built-in commands is very fast. It is essentially a self-contained function ...
