1.起始
事情一开始是这样的，这一块是从自动寄存柜上拆下的屏幕。已经放置了两三年了，我想着给它用一下。具体的型号是M128128-1B1
使用的是少见的22pin脚位
然后很神奇，这玩意现在居然要卖几百块钱，这种几千都是虚标价格，实际价格应该在200-300之间，或者也没人知道具体多少。
但是以前的价格我们还是可以查到的，像是这一块Truly M128128只要十几块钱
这一个屏幕并不是太好驱动，最大问题是资料极其难找，我试着搜索Truly或者搜索128128都是不同的结果。
2.关于Truly
3.参考手册
truly-msp-g128128dyly-2w? 这个是其中一种g128128的，m128128的没找到
在线地址 ?truly-msp-g128128dyly-2w - 道客巴巴
4.参考程序
avr_truly_M240128driver??
在线地址
??avr_TRULY_M240128driver - 源码下载|嵌入式/单片机编程|单片机(51,AVR,MSP430等)|源代码 - 源码中国
5.资料分析
看了一眼这个g128128的居然是1998年的资料 ?，也因此相关的内容非常难找
引脚的对应，但要注意这个是g128128，我看了一下，LEDA和LEDK是分别对应21，22
整个的原理图
驱动这一个屏幕，需要提供5V的电压，所以使用5V的MCU来控制是最好的，当然如果说单独提供电压给MCU，也可以用3.3V的来控制逻辑部分。另外有背光的驱动，需要提供高达380mA的大电流，背光的电压要控制在不超过4.6V典型为4.2V。
这也就是说背光的驱动上必须要加电阻至少加一个10欧姆（调试时候应该要加100欧姆）
但是同时我又找到一张m128128的资料，可以看出来用的液晶面板是有所不同的，模组的尺寸相差有一些，但是基本一致
这个是M128128
对比一下可以发现，是把东芝芯片换成了环氧树脂封装的某种芯片
另外还找到了M320240
这个是安装在这样的一个地方上，配的处理器还是ARM
6.突破口，唯一的程序
然后还好我更多的搜索了一下，终于在数码之家找到有一位网友可以点亮这一个屏幕的了，可以知道屏幕是使用KS0108，原帖地址 http://bbs.mydigit.cn/read.php?tid=2507002
最重要是给出来引脚图
和实际的进行一下对应，他上面写的加了一个数字行后非常容易引发误解。我通过K和A进行确认后确认这一引脚可能是对的。

}7.驱动的修改与移植
我要移植到Arduino IDE上面，这样方便减少开发时间。
VO不用连接，然后测试时候应该A和K也不用连。
我在上面一个为基础的情况下修改了代码，但是，不能正常的驱动，因为接线或者其他什么原因，VCC和GND的电压一直不够。不管怎么样，当做一个参考来吧
