尝试自己做一个复古游戏机Arduboy学习之路 1.NANO+I2C_OLED
手里只有arduino micro板子和I2C接口的OLED，而Arduboy用的OLED是SPI接口的，需要修改底层。
买了SPI接口的OLED还在路上，手痒怎么办。
看到一个帖子【如果但不开，就需要FQ看】：
https://community.arduboy.com/t/arduboy-on-arduino-nano-i-c-display/5532
功能是用NANO+I2C接口的OLED做。
但是楼主说法因为换了内核，好多bug，比如内存太小有些游戏不能忘，绿色LED不会PWM控制等等。
但是还是值得尝试一下
虽然帖子不好打开，但是github在国内还是容易打开的，顺利下载了源码：
https://github.com/harbaum/Arduboy2
README内帖子内也有接线图，也有fritzing的原图直接可以打开
很兴奋，下载了hellowworld源码到我的micro板子上，结果没驱动起来OLED，估计底层需要修改，先挖坑
算了，先找个NANO板子试试代码吧
烧录成功，而且OLED也成功点亮，显示helloworld
成功了一大半，其它的按键，LED，蜂鸣器都是其次，没难度。也就不研究了。
看下这个源码和官方Arduboy2的区别，看能不能修改到arduino micro板子上能用
这样和原装Arduboy对比都是ATMEGA32U4平台，只是修改一个OLED的SPI接口到I2C，应该代码不会出太多问题，只是液晶驱动速度可能会慢一些，至少可以先玩玩啊。
先看看这个源码，Arduboy2Core.h文件里面增加定义了如果内核是328p，就是当是NANO或者UNO时候的引脚定义。

/** \brief
* Eliminate the USB stack to free up code space.
*
* \note
* **WARNING:** Removing the USB code will make it impossible for sketch
* uploader programs to automatically force a reset into the bootloader!
* This means that a user will manually have to invoke a reset in order to
* upload a new sketch, after one without USB has be been installed.
* Be aware that the timing for the point that a reset must be initiated can
* be tricky, which could lead to some frustration on the user's part.
*
* \details
* \parblock
* This macro will cause the USB code, normally included in the sketch as part
* of the standard Arduino environment, to be eliminated. This will free up a
* fair amount of program space, and some RAM space as well, at the expense of
* disabling all USB functionality within the sketch (except as power input).
*
* The macro should be placed before the `setup()` function definition:
*
* \code{.cpp}
* #include <Arduboy2.h>
*
* Arduboy2 arduboy;
*
* // (Other variable declarations, etc.)
*
* // Eliminate the USB stack
* ARDUBOY_NO_USB
*
* void setup() {
* arduboy.begin();
* // any additional setup code
* }
* \endcode
*
* As stated in the warning above, without the USB code an uploader program
* will be unable to automatically force a reset into the bootloader to upload
* a new sketch. The user will have to manually invoke a reset. In addition to
* eliminating the USB code, this macro will check if the DOWN button is held
* when the sketch first starts and, if so, will call `exitToBootloader()` to
* start the bootloader for uploading. This makes it easier for the user than
* having to press the reset button.
*
* However, to make it even more convenient for a user to invoke the bootloader
* it is highly recommended that a sketch using this macro include a menu or
* prompt that allows the user to press the DOWN button within the sketch,
* which should cause `exitToBootloader()` to be called.
*
* At a minimum, the documentation for the sketch should clearly state that a
* manual reset will be required, and give detailed instructions on what the
* user must do to upload a new sketch.

* The RGB LED is actually individual red, green and blue LEDs placed
* very close together in a single package. This 3 parameter version of the
* function will set each LED either on or off, to set the RGB LED to
* 7 different colors at their highest brightness or turn it off.
*
* The colors are as follows:
*
* RED LED GREEN_LED BLUE_LED COLOR
* ------- --------- -------- -----
* RGB_OFF RGB_OFF RGB_OFF OFF
* RGB_OFF RGB_OFF RGB_ON Blue
* RGB_OFF RGB_ON RGB_OFF Green
* RGB_OFF RGB_ON RGB_ON Cyan
* RGB_ON RGB_OFF RGB_OFF Red
* RGB_ON RGB_OFF RGB_ON Magenta
* RGB_ON RGB_ON RGB_OFF Yellow
* RGB_ON RGB_ON RGB_ON White

* Using the RGB LED in analog mode will prevent digital control of the

* Many of the Kickstarter Arduboys were accidentally shipped with the
* RGB LED installed incorrectly. For these units, the green LED cannot be
* lit. As long as the green led is set to off, turning on the red LED will
* actually light the blue LED and turning on the blue LED will actually
* light the red LED. If the green LED is turned on, none of the LEDs
* will light.

这里面没有需要的OLED的驱动方式修改的地方，继续看Arduboy2Core.cpp
这里我们发现了增加OLED液晶驱动的部分
那么，要改到micro上，感觉主要就是这两个文件了，挖坑以后补
