SCM Electronic Clock: 6 digital control time
单片机的电子时钟:6个数码管分时循环工作,刷新频率≥25Hz。键盘采用矩阵式电路,L1-L4作为输出,H1-H4作为输入。(详细工作原理请参考教材第10章)。
系统时钟采用12MHz,采用定时器方式2计时-SCM Electronic Clock: 6 digital control time-cycle work, refresh frequency ≥ 25Hz. Keyboard, a matrix circuit, L1-L4 as the output, H1-H4 as input. (Details please refer to teaching works Chapter 10). The system clock is 12MHz, using the timer mode 2 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 r0, = 0x40021000
ldr r1, = 0x14D83
str r1, [r0]
gsszbz:
ldr r2, [r0]
ldr r1, = 0x20000
tst r1, r2 @高速时钟标志位
