The second course is designed to spring 2019 report
First, the pilot project name
Real-time clocks
Second, the experimental project functional description
Corresponds to a timer, calculation of minute by rotating the second hand, the minute hand is calculated by the rotation of the hour a timepiece.
Third, the project introduces modular structure
Step One: Draw static seconds. That is the definition of the center coordinates of the starting point of the second hand, the length of the second hand is defined, the end point coordinates. Using the model and function setting line widths, drawn last seconds.
Second step: rotation of the second hand. Variables defined as an angle corresponding to the second hand, the knowledge obtained by using trigonometry end coordinates of the second hand.
Third step: rotation of the actual time. Defined system variables (SYSTEMTIME), acquires the current time by GetLocalTime (& ti), the second hand of the angle determined by the actual time.
The fourth step; add hour and minute hands. In length, width, color, rotation speed different and each has a corresponding value.
Step Five: Add a dial scale. Drawing dial function using the output character on a screen, so that rotation of the hour and minute hands more natural.
Fourth, implement the interface display
