摘要
目前大多数电子胸牌显示方式单一,显示内容不能随意更改,功耗和成本较高,体积较大,不适合随身携带。为了克服以上缺点,本文设计的电子胸牌采用ARM Cortex-M0内核的LPC1112主控芯片,能够实现8种动态显示方式,通过按键切换显示方式可实现开机自检,并且可通过USB接口方便地更新显示数据。
Most of the current electronic chest card display is single, the display contents can not be altered, and the design has large power consumption, higher cost and larger volume;therefore, it is not suitable for carrying. In order to overcome the above shortcom- ings, the electronic chest card takes LPClll2 master chip based on ARM Cortex-M0 kernel, and can achieve eight kinds of dynamic dis-play, and power-on self-test through switching over the display mode by the key, and it can easily update the display data through the USB interface.
