[单片机开发] USBASP+固件升级指南
玩arduino的朋友应该都知道常用的arduino的处理器几乎都是atmega系列的单片机（AVR单片机一种）想要更加灵活的玩转arduino的莫过于自己制作一块arduino主板，但这就带来了一个问题——BootLoader的烧录（也就是引导程序的烧录）
arduino的BootLoader不能使用串口烧录这是常识（我个人认为），唯一的办法就是编程器（也叫烧录器或下载器）
可以将一块arduino板子制作成arduinoISP，但据说并不稳定，有一定概率烧录失败（我并没有有试验过，所以具体情况我也不太清楚，用过的可以说一下）
还有就是目前最便宜的编程器也就是是USBasp（国内大部分AVR单片机用的都是这种），
Friends playing with Arduino should know that most of the commonly used processors of Arduino are Atmega series single-chip computers (AVR single-chip computers). The most flexible way to play with Arduino is to make an Arduino motherboard by yourself, but this brings a problem -- bootloader burning (that is, bootloader burning)
Arduino's bootloader can't use serial port to burn. It's common sense (I personally think) that the only way is to program (also called a burner or downloader)
You can make an Arduino board into an Arduino ISP, but it's said that it's not stable, and there's a certain probability of burning failure (I haven't tried it, so I'm not sure about the specific situation, so I can say what I've used)
And the cheapest programmer at present is USBASP, (2020-01-07, C/C++, 3768KB, 下载1次)

[单片机开发] STM32_NES
在STM32上制作的NES模拟器，不需要外部RAM，不需要NOR、NAND、SPIflash等，直接使用stm32片上外设。超频至128M后还算基本流畅，能玩一些64K以下的nes游戏，超级玛丽、坦克大战等。

在这个实验中最重要的是时序，因为要精确到us，所以找到合适的延时函数很重要。之前网上有一些关于51的和PIC的精确延时函数，我试了下，还要去仿真，很不方便，后面搞了很久发现了一个很好的延时函数，我已经把它用红色标注出来了，抓好了延时，这程序基本没什么问题了。
In this experiment is the most important thing in sequence, because want to us, so it s very important to find a suitable time delay function. Before there are some about 51 and precise time delay function of PIC, I tried, but also to the simulation, is not very convenient, back to for a long time found a very good time delay function, I have marked out in red, it pays special attention to the time delay, this basically no problem.

[单片机开发] lcd
用到段码液晶屏，一般是用专用驱动芯片如：HT1621等，考虑到，成本、功耗，决定用单片机直接驱动。液晶屏手册建议用1/3偏压，求简单用1/2偏压，实际搭了个实验板试了一下，效果还是不错的。实际可将分压电阻R2-29加大到1M，和用CPU的一个脚来驱动（可关断），进一步减小功耗，现贴出原理图、程序、照片，供有用者参考。
Used Segment LCD, special driver chip, such as: HT1621, taking into account cost, power consumption, and decided to use the single-chip direct drive. LCD manual recommends 1/3 bias, 1/2 bias the sake of simplicity, the actual take a experimental board tried it, the effect is good. The actual dividing resistor R2-29 increased to 1M, and with a pin to drive the CPU (OFF), and further reduce power consumption, schematics, procedures, Photos were posted, useful for reference.

硬件开发的基本过程
产品硬件项目的开发，首先是要明确硬件总体需求情况，如CPU处理能力、存储容量及速度，I/O端口的分配、接口要求、电平要求、特殊电路（厚膜等）要求等等。其次，根据需求分析制定硬件总体方案，寻求关键器件及电咱的技术资料、技术途径、技术支持，要比较充分地考虑技术可能性、可靠性以及成本控制，并对开发调试工具提出明确的要求。关键器件索取样品。第三、总体方案确定后，作硬件和单板软件的详细设计，包括绘制硬件原理图、单板软件功能框图及编码、PCB布线，同时完成开发物料清单、新器件编码申请、物料申领。第四，领回PCB板及物料后由焊工焊好1～2块单板，作单板调试，对原理设计中的各功能进行调测，必要时修改原理图并作记录。第五，软硬件系统联调，一般的单板需硬件人员、单板软件人员的配合，特殊的单板（如主机板）需比较大型软件的开发，参与联调的软件人员更多。一般地，经过单板调试后在原理及PCB布线方面有些调整，需第二次投板。第六，内部验收及转中试，硬件项目完成开发过程。
