3、编写口令程序
要求:
1) 口令是随系统时间而变动的。(在输入口令前应先把当时的系统时间显示在屏幕上)
2)口令输入有次数限制。(口令与时间有关,但不能直接输与显示在屏幕上时间的数值,应进行运算。
3)、口令输入正确后进入选歌菜单,可选3首以上歌曲,可任意停止返回菜单。-3, the preparation of password procedures require: 1) The password is with the system changes over time.

STM32汇编LCD初始化
应用背景
本人原创STM32汇编实现LCD的显示,目前搜遍全球也没有STM32汇编实现LCD显示的代码。 编译器 ARM-NONE-EABI ,是在LINUX下编译的。
代码很复杂不容易看懂,我用了很长时间才写出来,大概有1000行汇编代码,写了半个多月才写出来,真是不容易啊。 程序包括IO设置 时钟初始化,NVIC中断设置,定时器,温度传感器等,红外遥控, 然后在LCD上显示
关键技术
初始化代码

ldr r1, = 0x20000
tst r1, r2 @高速时钟标志位
