更新，这次终于可以自行运行ROM启动程序了

（之前的是测试工具相当于数据都是灌到嘴巴里的，但是这次是用一个简易的pc计数器来控制的，排除了一些实际运行中的错误）

离目标又近了一步

剩下的就是时间对它的考验了，鬼知道以后还会遇到多少问题

继上文，电路板画好了

不过还有一块位置剩下来，不知道做什么（这是两块板子之一）（笑）

他我知道，就是benblue嘛，不过那些并不是他自己做，而是搬运并配音国外的beneater的视频，然后还顺带把套件搬运到国内来，中间的利润估计也挺大的，不过搬运了这么多视频似乎也可以体谅，不知视频和套件是否获得原作者的许可，具体什么来头不大清楚

把上下两张板子做好了，可以看看

以后文件直接上传github，方便控制版本：

XXXXXXXXXXXXXXXXXX/Left-Hand/74-gate-computer

不过kicad的覆铜不敢恭维，只要是封闭图形中间就不覆铜，而且线距比较大（如果有更改选项的方法请告诉我），所以我一般是导入到立创之后生成gerber。不过这几天疫情嘛，打板恢复到20元了，不打也得打，只不过心里在滴血。

关于其他单元是否要做板子的话另议，一般先会用洞洞板做

接下来我检查一下库存，看看是否有缺少的元件

杂谈：最近入手了一个低压烙铁控制板，看看是否能加一个t12的头上去，我这个黄花907还是有些问题，可能存在漏电的现象（我家住顶层，还没有可用的地线）上次的一个芯片可能就是因为这个原因烧掉了，为避免经济损失，打算用这个自己做一个烙铁

把vga显卡做好了，显示的分辨率为256*240 60hz

vga.dig 185.01KB DIG 43次下载

通过在总线操作写入x，y地址，数据来实现图片的写入。使用了4块is62c256的sram进行乒乓工作，两块sram构成一个帧，一个帧在显示的同时写入另一个帧。8位色，届时通过R2R电阻分压网络实现DA。支持Y方向上的硬件滚屏，（x应该会考虑，方便制作多向卷轴，不过再加上去就占位置了），总计元件费约为70元，其中20元用于sram，亦可做其他开发板的显示模块

顺便说一下打板子的事,其实我一开始是想说尽早把之前的板子打掉了，但是看到20元钱心里还是很犹豫，现在都拖了这么久了，干脆就等到底吧

最近有空吧代码读取的部分做了，第一次给这个写真正意义上的程序(在vga上显示一个句号)

顺便做了一个编译器
