ARM7
Epidemic also soon pass, at the last moment, I hope you can not be taken lightly, protect yourself, protect your family.
This blog is a summary of the ARM7 course of the semester. The occurrence of the epidemic, in response to the party's call, I have been at home, self-limits. An early age I wanted to write this blog post, but ARM7 too old, so I gave up the idea. Until now, when I cleared space, I turn to the ARM7 project. Think about the process of writing, it is sad to delete, so I put it here. ARM7 though old, but enough for learning.
I am here not described in detail, if you have friends like it, leave a message exchange. I was using the chip is NXP LPC2138. There are tools used by AD, KEIL, VSCODE. Associated software can install your own Baidu, Baidu is very powerful.
The PCB and schematics are in the file. Circuit diagram which there are some caveats.
1. The crystal must be very close to the chip, otherwise it will not oscillate.
2.P0.3 P0.4 mouth or what was it, remember. In short, P0.? The mouth can not be used.
3. After the welding in accordance with the conventional crystal, the program, the use of the serial port, baud rate function alone is raised to 4 times the normal, based on the normal UCOSII. So far we did not get to know.
4.P0.14, P0.11 have pull-up resistors.
Specific steps I can not send, there is no need, after all, it is too old.

本来是按照游戏机的形式去画的图，但是画图的时候被芯片坑了，无法将LCD很好的集成上去。不过还是实现了简单的贪吃蛇。俄罗斯方块的话，主要是没时间了，有兴趣的朋友可以去看看我的另外一篇博文，或许会有帮助，毕竟移植嘛。由于水平有限，那是我写的比较漂亮的东西了，虽然还有很多，但是由于很多原因没有保存下来，难受。看到这里，你也发现我没有状态了吧，的确，我开始闭关考研了，21考研，还请祝我成功。下方有所有文件的下载方式，如果你需要，但是没有积分的话，你可以联系我，都是学习罢了。
好了，开始闭关了。任何不曾起舞的一天，都是对生命的辜负。迷茫，还有多久是个头，两年吗。he
