U8g2库支持的屏幕类型总表以及构造器选择

U8g2库支持类型的屏幕总表：https://github.com/olikraus/u8g2/wiki/u8g2setupcpp
U8g2库构造函数列表：https://github.com/olikraus/u8g2/wiki/u8g2setupcpp#links

介绍

要设置u8g2，请为显示选择正确的构造函数。构造函数名内包含：定义了显示类型、控制器、RAM缓冲区大小和通信协议。如果显示不完全，请尝试使用相同显示控制器名称的构造函数。

构造函数的参数定义了显示的旋转以及显示如何连接到Arduino板。这是Arduino c++接口的“Hello World”示例:

U8g2 支持3中不同的绘图模式

全屏缓存模式
页面模式（U8glib 图片轮询）
U8c8，纯字符模式

全屏缓存模式（full buffer）

快速
可使用所有的图形程序
需要大量的内存（RAM）
从上面支持的类型中选择一个 U8g2 的构造器，全屏缓存模式的构造器包含了“F”，比如：

U8G2_ST7920_128X64_ F _SW_SPI(rotation, clock, data, cs [, reset])

使用方法

清除缓存内容：u8g2.clearBuffer()。
使用绘图指令绘制图形。
发送缓存数据给显示器以显示：u8g2.sendBuffer()。

void setup(void) {
  u8g2.begin();
}

void loop(void) {
  u8g2.clearBuffer();
  u8g2.setFont(u8g2_font_ncenB14_tr);
  u8g2.drawStr(0,20,"Hello World!");
  u8g2.sendBuffer();
}

页面模式（U8glib 图片轮询）

所有的图形程序可用
要求少量的内存（RAM）
速度慢
从上面支持的类型中，选择一个 U8g2 的构造器，全屏缓存模式的构造器包含了“1”，或者“2，”比如：

U8G2_ST7920_128X64_ 1 _SW_SPI(rotation, clock, data, cs [, reset])

使用方法

调用 u8g2.firstPage()
运行一个 do-while 循环
在循环体内绘制一些图形
循环到U8g2.nextPage()返回真结束

void setup(void) {
  u8g2.begin();
}

void loop(void) {
  u8g2.firstPage();
  do {
    u8g2.setFont(u8g2_font_ncenB14_tr);
    u8g2.drawStr(0,24,"Hello World!");
  } while ( u8g2.nextPage() );
}

U8x8 字符模式

快速
不需要内存（RAM）
不能绘制图形
不支持所有显示控制器
从上面支持的类型中，选择一个 U8g2 的构造器，全屏缓存模式的构造器包含了“1”，或者“2，”比如：

U8G2_ST7920_128X64_ 1 _SW_SPI(rotation, clock, data, cs [, reset])

使用方法

所有的绘制指令直接写入显示器

void setup(void) {
  u8x8.begin();
}

void loop(void) {
  u8x8.setFont(u8x8_font_chroma48medium8_r);
  u8x8.drawString(0,1,"Hello World!");
}

构造函数的名字

Arduino c++构造函数的名称有以下几个部分:

序号	描述	示例
1	前缀	U8G2
2	显示控制器	UC1701
3	显示名称	DOGS102
4	Buffer Size	1, 2 or F (full frame buffer)
5	描述	4W_SW_SPI

这些部分与_相连。示例的完整构造函数名是U8G2_UC1701_DOGS102_1_4W_SW_SPI。上面列出了所有可用的构造函数名.

Buffer Size(缓冲区大小)

```c
#include <Arduino.h>
#include <SPI.h>
#include <U8g2lib.h>

/* Constructor */
U8G2_UC1701_DOGS102_1_4W_SW_SPI u8g2(U8G2_R0, /* clock=*/ 13, /* data=*/ 11, /* cs=*/ 10, /* dc=*/ 9, /* reset=*/ 8);

/* u8g2.begin() is required and will sent the setup/init sequence to the display */
void setup(void) {
  u8g2.begin();
}

/* draw something on the display with the `firstPage()`/`nextPage()` loop*/
void loop(void) {
  u8g2.firstPage();
  do {
    u8g2.setFont(u8g2_font_ncenB14_tr);
    u8g2.drawStr(0,20,"Hello World!");
  } while ( u8g2.nextPage() );
  delay(1000);
}

Buffer	Description
1	Only one page of the display memory is stored in the microcontroller RAM. Use a firstPage()/nextPage() loop for drawing on the display.
2	Same as 1, but maintains two pages in the microcontroller RAM. This will be up to two times faster than 1.
F	Keep a copy of the full display frame buffer in the microcontroller RAM. Use clearBuffer() to clear the RAM and sendBuffer() to transfer the microcontroller RAM to the display.

The full buffer F option can be used only, if there is sufficient RAM available in the microcontroller. Use option 1 or 2 on a microcontroller with a small amount of RAM. The u8x8 API can be used if there is not even RAM for one page.（翻译：只有当微控制器中有足够的RAM可用时，才可以使用全缓冲区F选项。在带有少量RAM的微控制器上使用选项1或2。如果一个页面甚至没有RAM，也可以使用u8x8 API。）

通信协议是构造函数名称的一部分(参见上面)。支持以下通信协议:

Communication	Description
4W_SW_SPI	4-wire (clock, data, cs and dc) software emulated SPI
4W_HW_SPI	4-wire (clock, data, cs and dc) hardware SPI (based on Arduino SPI library)
2ND_4W_HW_SPI	If supported, second 4-wire hardware SPI (based on Arduino SPI library)
3W_SW_SPI	3-wire (clock, data and cs) software emulated SPI
SW_I2C	Software emulated I2C/TWI
HW_I2C	Hardware I2C based on the Arduino Wire library
2ND_HW_I2C	If supported, use second hardware I2C (Arduino Wire lib)
6800	8-bit parallel interface, 6800 protocol
8080	8-bit parallel interface, 8080 protocol

硬件I2C允许某些控制器类型的引脚重新映射。复位引脚后列出可选引脚编号:
..._HW_I2C([reset [, clock, data]]). Use U8X8_PIN_NONE if the reset input of the display is not connected.( 译文：如果显示的复位输入没有连接,使用U8X8_PIN_NONE)
This might be confusing, because the software emulated I2C constructor lists the required clock and data line before the reset pin:..._SW_I2C(clock, data [, reset])

使用动态分配的页面缓冲区

当使用动态内存分配时，函数*U8G2::begin()将被禁用。

出于这个原因，setup()函数必须在*U8G2::begin()函数的位置上有以下内容:

uint8_t *buf;
void setup(void) {
  buf = (uint8_t *)malloc(u8g2.getBufferSize());
  u8g2.setBufferPtr(buf);
  u8g2.initDisplay();
  u8g2.clearDisplay();
  u8g2.setPowerSave(0);
}

Rotation（用于屏幕显示的翻转角度）

软件模拟的显示旋转是构造函数的第一个参数。

Rotation/Mirror	Description
U8G2_R0	No rotation, landscape
U8G2_R1	90 degree clockwise rotation
U8G2_R2	180 degree clockwise rotation
U8G2_R3	270 degree clockwise rotation
U8G2_MIRROR	No rotation, landscape, display content is mirrored (v2.6.x)

If supported U8G2_R2 is identical to u8g2::setFlipMode(1).(译文：如果支持U8G2_R2与u8g2::setFlipMode(1)相同。)
