Description: ARM7综合实验。开发环境IAR，板子用的是YL-LPC2148。功能简介：通过UART（向量IRQ中断），接收上位机发来的控制命令，该命令控制蜂鸣器以特定频率鸣叫，同时利用LCD将蜂鸣器的鸣叫频率显示出来；通过开发板上外部中断源S4、S5（相量中断）获得外部输入0、1序列（按下S5代表1，S4代表0），将该序列发回上位机，同时LED闪亮以表示S4、S5操作有效。-ARM7 comprehensive experiment. Development Environment IAR, board using a YL-LPC2148. Features: through the UART (IRQ interrupt vectors), the receiving host computer sent the control command, the command control of a specific frequency tweet buzzer, LCD will also use songs and calls of buzzer frequency is displayed through the development of on-board external interrupt Yuan S4, S5 (phase volume break) 0,1 sequence of external input (press the S5 on behalf of 1, S4 representative of 0), the sequence back to PC, while LED flashes to indicate S4, S5 operate effectively.
