stc8h8k64u利用硬件SPI模式驱动ST7567液晶12864屏幕

nok*** · 发表于 6 天前

2023年在数码之家论坛申请了开天斧三的开发板，试了一次就吃灰了。前几天打算做个小东西，利用红包买了几个STC8H8K64U的单片机，之前大学就玩过STC89系列的，看了下stc8系列的使用前要初始化引脚，因为没系统学过，在这里载了大跟头。买了本丁向荣老师的“单片微机原理与接口技术-基于stc8h8k64u”，感觉比文档分了条理。拿出来在数码之家那里收集的屏幕，就是建设银行优盾拆的屏幕，128x64像素，带背光很适合再次利用。

cog是st7567已经明确了，驱动就好办了。但是之前一直是89系列模拟SPI时序驱动，这次想玩玩硬件驱动的，可惜《单片微机原理与接口技术-基于stc8h8k64u》里的范例给的是SPI管理25系列ROM，可以参考但有限，网上搜也没找到这个型号的，那就自己折腾。

CPHA=0, CPOL=1, 我的理解是这样的：（为了简单测试成功。我采用单片机做主机，lcd从机，忽略ss引脚，cs一直拉低）

LCD_Init里初始化st7567的参数是来自数码之家 ID：lizi 的st7565源码，修改了对比度值为0x28，

Display_Char函数是为了显示font16.h文件内字符设计的。Display_Chars顾名思义显示字符串，

源码，取模软件，st7567.pdf 已打包，keil5测试没问题。

有一个问题，我怎么感觉硬件spi和软件spi没啥区别啊，能节省多少资源呢？因为我是爱好者不知道实际开发中存在的问题，我想做的是STC8H8K64 + HWL8110（uart通信，电量统计的芯片）+st7567+UART蓝牙无线发送一点数据。这个工程我需要注意什么？欢迎赐教。
最终感谢stc公司送我的开天斧三开发板，

下载时6-24Mhz都可以，应该是我对st7567没看完，也不知道F_OSC/16 (24MHz/16=1.5MHz)怎么取值，就按照模拟spi随意取大的，估计浪费了单片机时间。页请交大佬，这个屏幕的SPI时钟到底怎么看，我脑子晕晕的。

下载时6-24Mhz都可以，应该是我对st7567没看完，也不知道F_OSC/16 (24MHz/16=1.5MHz)怎么取值，就按照模拟s ...

一般手册里有这种时序图，只要时序在规定范围内都可以。
另外硬件spi当然模拟spi优先使用，无论是节省mcu时间还是配合dma\p2p(Ai8051U系列)等功能使用。
