stm32纯汇编LCD显示

yjmwxwx · 发表于 2015-5-24 14:30:32

板子是正点原子的miniSTM32开发板，读液晶返回的ID是4535（程序中没用读液晶代码）。

程序实现时钟初始化、IO设置、LCD初始化、LCD画背景色、LCD显示字符几个部分。

红底蓝子大概在中间位置显示：

程序不大，搞了两天才弄出来。程序代码极其不规范，没有利用堆栈传送数据等
工具链 gcc-arm-none-eabi

再加个功能红外遥控用LCD现实几号按键跟显示按键的码值

LCD显示     STM32ASM

                   HONGWAI      16753245
                   ANJIAN       01

HONGWAI显示按键的码值，由于程序没有十六进制显示程序所以显示的是十进制，要看十六进制数用计算器转换就行了，转换过来是 0x00FFA25D
ANJIAN显示几号按键，必须码值一样才能显示几号按键，换别的遥控器不影响上面HONGWAI的显示。

汇编其实一点用也没有，我搞汇编完全是瞎搞，一点参考价值都没有。

其实我是地道的农民，小学文化基础差的不能再差了，我的主业是种庄稼。

我学STM32走了岔路。。。其实我还搞过STM32的反汇编，用的是IDA
