摘要
该装置实现了对LED线阵显示以及80*80 mm黑白图文卡信息的快速录入。装置由旋转LED部分和主控部分组成,两个部分之间通过蓝牙通信。所有显示信息由主控部分人机交互录入或通过图文卡快速录入,再通过蓝牙发送到旋转LED部分显示。能够完成在120°显示区域内任意线显示控制、双线上下移动动画、两块16*16点阵显示及宽窄变化。使用openMV摄像头完成图像识别、匹配,准确检测出图文卡信息,并通过TFT屏显示、LED线阵显示。装置能够通过调整PWM,完成对LED线阵显示的颜色控制。
The device realizes the fast input of LED linear display and 80*80 mm black and white image card information.The device consists of a rotating LED part and a main control part,and the two parts communicate with each other through Bluetooth.All display information is input by human-computer interaction of the main control part or by graphic card,and then sent to the rotating LED part for display through Bluetooth.It can complete any line display control,double line up and down moving animation,two 16*16 dot matrix display and width change in 120°display area.Openmv camera is used to complete image recognition and matching,accurately detect the information of image card,and display through TFT screen and LED linear array.The device can control the color of LED linear display by adjusting PWM.
