兼容源地工作室, STM32F429IGT6核心板+NandFlash+SDRAM+SPIFlash+EEPROM （A1型）
http://vcc-gnd.com/rtd/html/STM32/quickref.html
由于4.3寸屏没有显示内存，只能通过再附加一个另外的驱动芯片才有可能让stm32驱动起它，
LCD4342包含了处理芯片和转接板（有两个屏线接口），并非纯裸屏
所以要注意LCD4342引出的40pin规范跟4.3寸裸屏的40pin是不同的 -
目前已知可以用WiringPi驱动的Rasperry Pi HAT有这些：

我找到第三种方法可以得到3.3V和5V稳定杜邦线输出的大功率电源
（普通电池无法驱动树莓派等非低功率单片机，除非背靠背8节电池组），
方法是多路电压转换模块+DC接口电池扣+9v电池。
除了这种方法以外，我还想到两种办法，第一种办法是自制2节18650充电宝+st-link v2；
第二种办法需要自己用洞洞板焊接，用焊锡飞线，把电池扣焊接在并联的AMS1117-3.3V和AMS1117-5V模块
（先把9v降压到5v，再降压到3.3v），再用拨动开关控制电源开关

通过usb host读取USB HID键盘键值，然后转4线串口的方法，网上有一种做法是通过CH9350L或者CH9350来实现。
这个芯片的串口协议需要查资料，我查过和用sscom测试过（我用的是润和Neptune开发板+键盘HID套装）
大概是这样子：CH9350L会不断发送57 AB 82 A3（波特率115200），夹杂键值16进制数据，可以通过接收
57 AB 12 00 00 00 00 FF 80 00 20来关闭（也可以不关闭）。如果键盘按键按下（不包括键盘按键弹起），
例如a，会发送一段16进制数据57 AB 88 0B 10 00 00 04 00 00 00 00 00 16 1A （一共15个字节），
其中第8个字节04是a的键盘码
