4x4 keyboard input P2 for P1 for output (note the connection)

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 shizhong:     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                bne rccchushihua     b gsszbz rccchushihua:     ldr r0, = 0x40022000     mov r1, # 0x00000032     str r1, [r0]       &n

24c02应用,在家用电器控制系统中经常有这类的应用.-24C02 applications, in household appliances control systems often have this kind of application.

此代码是利用汇编语言实现的霓虹灯变化，实现都种图案的变化。是很好的汇编语言学习实例。-This code is to use assembly language to achieve the neon lights change to achieve all kinds of design changes. Is a good example of assembly language to learn.

8255的汇编程序，各种工作方式尽有，是初学者学习的好帮手，也是利用8255扩展IO的普遍方法，只用改下地址直接拿去用就行-8255 compilation of procedures, a variety of working methods have to do is a good helper for beginners to learn, but also the use of 8255 to expand the universal method of IO only change taken directly under the address used on the line

我实验板带的实验程序，留给初学者看看吧，其他的我再整理一下，陆续上传吧-I experiment with the experimental procedure sheet, leaving beginners take a look at it, other like me to organize a series of upload it
