Echart polar coordinates, azimuth and distance diagram, icon symbol rotation and size, color gradient
Background: Participating in an interactive chart project, the customer had a need for polar coordinate comparison to display different types of indicator data in different directions and distances. Specifically, the attribute fields are: Source, distance, orientation, ID, rotation angle, size Let’s look at the renderings first: Technical points: Legend description: The distance is the radial […]
Zhengdian Atom embedded Linux driver development – Linux DAC driver
In the last note, I learned about the ADC driver. STM32MP157 also has DAC peripherals. The IIO driver framework also used by DAC. In this chapter, we will learn how to use the DAC on STM32MP157 under Linux as follows. Introduction to DAC ADC is an analog-to-digital converter, responsible for converting external analog signals into […]

Merge Sort merge Sort + diagram + recursive / non-recursive
The main idea of (merge sort) is: to merge gradually several ordered sequences, and finally merge them into one ordered sequence Two-way merge sort(2-way merge sort) is the simplest sorting method in merge sort (1)Recursive implementation of two-way merge sort // Recursive implementation of two-way merge sort void merge(vector<int> & amp; arr,int left, int mid, […]
CDialogBase MFC dialog base class
Based on the dialog base class abstracted from message mapping, business development only needs to inherit this class. This parent class can already meet a large number of business scenarios. For example, creating a modal dialog box or a non-modal dialog box, etc., is only encapsulated. #pragma once #include “common.h” /****************************************************** ************************/ /* \t Based […]
