摘要
采用STM32F103系列STM32F103RET6两片单片机作为核心器件,通过红外数据接收器接收录入的图文信息,利用高精度算法优化,采用16个共阴极红绿双色LED灯显示图形,设计并制作了一个LED线阵示装置。通过电机带动LED线阵高速旋转,由于人眼的视觉暂留现象,看到的显示内容效果跟平面连续显示效果一样。通过多次测试,LED线阵显示效果均达到预期要求。
In this paper,STM32F103 series STM32F103RET6 microcontroller is adopted as the core device,the input text information is received through the infrared data receiver,the high-precision algorithm is used to optimize and the display graph of 16 co-cathode red and green LED lights is used to design and make an LED linear array display device.Driven by the motor,the LED linear array rotates at a high speed.Due to the temporary retention of human eyes,the display effect is as same as the planar continuous display effect.Through many tests,the display effect of LED linear array has reached the expected requirements.
