基础组件实现
我们现在离手搓一个动态的多级菜单越来越近了。终于！我们来到了最基础的组件实现，我们现在搓的东西的代码库放到了：MCU_Libs/OLED/library/Graphic/widgets/base at main · Charliechen114514/MCU_Libs (github.com)当中，也就是手搓图像显示和文字显示。如果你对这篇博客所属的集合有任何疑问，可以到从0开始使用面对对象C语言搭建一个基于OLED的图形显示框架-CSDN博客阅读。
如何将图像和文字显示到OLED上
三个字：画出来！带上一个KeysKing大跌手搓的取码地址：波特律动LED字模生成器 (baud-dance.com)，实际上，你的悟性足够高，已经可以离开这篇博客自己继续手搓了。
好吧，你继续往下看了，那我就详细的好好说明。
如何绘制图像
绘制图像之前，我们还要遵循老步骤，思考一下如何设计我们的抽象。
我们如何描述一个给定的图像呢？我们可能着急于描述这个图像表达了什么，也就是图像的资源，在OLED中，我们习惯于阐述为一个字节的数组，这个数组描述了我们的图像，只要把它传递上去，一个图像就显示出来我们可以看了。
但是还是有问题：你这个图像放到哪里呢？画的要多大呢？这就是我们需要设计一个结构体抽象的原因了。请看VCR：
typedef struct __CCGraphic_Image{
CCGraphic_Point point;
CCGraphic_Size image_size;
uint8_t* sources_register;
}CCGraphic_Image;关于CCGraphic_Size，并不复杂，可以到MCU_Libs/OLED/library/Graphic/widgets/common/CCGraphic_Size at main · Charliechen114514/MCU_Libs (github.com)中看到源码，实际上就是宽和高的一个封装，没什么大不了的。
此外，我们对图像的操作就是绘制了
void CCGraphicWidget_init_image(
CCGraphic_Image* image,
CCGraphic_Point tl_point,
CCGraphic_Size image_size,
uint8_t* sources_register
);
void CCGraphicWidget_draw_image(
CCDeviceHandler* handler,
CCGraphic_Image* image
);出乎你意料的是。绘制图像远远比你想象的简单的多
#include "Graphic/widgets/base/CCGraphic_Image/CCGraphic_Image.h"
#include "Graphic/CCGraphic_device_adapter.h"
void CCGraphicWidget_init_image(
CCGraphic_Image* image,
CCGraphic_Point tl_point,
CCGraphic_Size image_size,
uint8_t* sources_register
)
{
image->image_size = image_size;
image->point = tl_point;
image->sources_register = sources_register;
}
void CCGraphicWidget_draw_image(
CCDeviceHandler* handler,
CCGraphic_Image* image
)
{
if(!image->sources_register) return;
handler->operations.draw_area_device_function(
handler, image->point.x, image->point.y,
image->image_size.width, image->image_size.height, image->sources_register
);
}我们直接使用设备draw_area的方法，将图像资源传递上去了。
CCGraphicWidget_draw_image -> draw_area_device_function(draw_area_device_oled) -> oled_helper_draw_area
你看，干净利落！完事。
如何绘制文字
现在这个事情就需要深思熟虑了，设计到文字，就必然需要考虑字体大小，以及解析字符串的问题。笔者这里没有实现UTF-8字符的打印实现，但是笔者提示你，仍然是画出来字符。让我们看看该咋做。
typedef struct __CCGraphic_TextHandle{
char* sources_borrowed; // 这个就是所持有的字体资源指针
CCGraphic_Point tl_point; // 这个是所占有的左上角的绘制起点
CCGraphic_Point indexed_point; // 这个是现在的绘制指针，表明现在我们绘制到了那个地方
CCGraphic_Size TexthandleSize; // 整个Text所在的BoundingRect大小
Ascii_Font_Size font_size; // 字体多大？
}CCGraphic_AsciiTextItem;如何获取字体？
关于ASCII字体的获取，笔者放到了附录里，值得一提的是，江科大的OLED_Data.h中对字体数组的初始化时不严谨的，不规范的，正确的初始化方案已经放到了附录，不再赘述。
如何正确的访问字体
C语言中，有一个著名的关键字叫extern，他随了汇编语言的关键字extern，在所属权层面上表达的同static完全相反，即这个资源的定义需要到其他文件中寻找。所以，当我们想要引用字体（这个字体被存放到了其他的C源文件中）的时候，只需要手动的extern一下，而且确保资源被正确的编译进来就OK了。
extern const uint8_t ascii6x8_sources[][6];
如何抽象字体
很简单，虽然说正常而言只需要抽象一个TextFont结构体即可，但是笔者认为这里更多看重的是方法，而且，没有必要对用户暴露一个Font结构体，选择结构体更加不如暴露的是一个枚举和公开的方法。

}题外话：使用编译宏控制资源编译：GCC是一个智能的编译器，对于任何没有使用到的资源，概不参与编译，所以，对于使用GCC的编译器，只需要确保自己不额外使用其他资源，就不会将冗余的C符号纳入编译。
但还是那句话，为了确保语义更加清晰，仍然使用控制宏对资源进行编译控制和符号控制，让自己的代码语义更加的明确，是一件事半功倍的举措
如何绘制字符串
绘制字符串是一个复杂的活。但是在那之前，把杂活做了。

)
{
item->font_size = text_size;
item->sources_borrowed = ""; // 初始化为空字符串，表示未设置内容。
item->tl_point = tl_point;
item->indexed_point = tl_point;
item->TexthandleSize = textHandleSize;
}

CCGraphic_Size textHandleSize
)
{
// 这个函数的一个重要的目的就是重定位文本框，为之后的文本显示做铺垫。
item->tl_point = tl_point;
item->TexthandleSize = textHandleSize;
}绘制一个字符串本身就是绘制一串字符，掌握整个原理，事情就会变得非常简单，我们线讨论如何绘制字符本身
/**

const char ch, Ascii_Font_Size size
)
{
borrowing_image->image_size = __fetch_font_size(size);
uint8_t* ascii = __select_from_ascii_font_size(size, ch);
borrowing_image->sources_register = ascii;
CCGraphicWidget_draw_image(device_handle, borrowing_image);
#if CCGraphic_TextDebug
device_handle->operations.update_device_function(device_handle);
#endif
}我们将一个字符的字体绘制文件放置到Image中，所以我强调：字符是画出来的。
设计缺陷：注意到，我这里并没有设置绘制的位置，这是因为这件事情在上层做好了，所以我也在参变量中警示自己：整个变量是部分初始化的。
绘制方案
我们绘制的时候，更多会去在乎：是在之前的文本基础上继续绘制呢？还是换一行继续绘制，还是直接清空文本重新绘制？为了防止反复的刷新，笔者设计了三个函数完成整个工作。
首先，设置游标点：
CCGraphic_Point indexed_point; // 这个是现在的绘制指针，表明现在我们绘制到了那个地方
整个在Text的结构体中，不由用户直接设置。
下面，就是依赖设置：
/**
* 判断当前字符是否需要换行。
* @param device_handle 设备句柄。
* @param brpoint 右下角边界点。
* @param cur_draw_p 当前绘制点的指针。
* @param s 字体大小枚举类型。
* @return 如果需要换行，返回非零值；否则返回零。
*/
static uint8_t inline __pvt_should_be_next_line(
CCDeviceHandler* device_handle,
CCGraphic_Point* brpoint,
CCGraphic_Point* cur_draw_p, Ascii_Font_Size s
)
{
return cur_draw_p->x +
(int16_t)(1.5 * __fetch_font_size(s).width) >= brpoint->x;
}
/**
* 计算有效的右下角点。
* @param device_handle 设备句柄。
* @param size 文本项的尺寸信息。
* @param tl 文本项的左上角起始点。
* @return 计算后的右下角点。
*/
static CCGraphic_Point inline __pvt_fetch_valid_final_point(
CCDeviceHandler* device_handle,
CCGraphic_Size* size, CCGraphic_Point* tl
)
{
CCGraphic_Point br;
int16_t device_width = 0;
device_handle->operations.property_function(
device_handle, &device_width, CommonProperty_WIDTH
);
int16_t device_height = 0;
device_handle->operations.property_function(
device_handle, &device_height, CommonProperty_HEIGHT
);
// 上面我们获取了设备的宽高，现在我们开获取最大的合法右下角的点
br.x = tl->x + size->width;
br.y = tl->y + size->height;
if(device_width < br.x) { br.x = device_width; }
if(device_height < br.y) { br.y = device_height; }
return br;
}文本绘制
绘制文本的本质是绘图。这一点务必注意。下面的整个函数实现了自动的文本换行！
/**
* 绘制ASCII文本项。
* @param device_handle 设备句柄，用于控制绘制设备。
* @param item 要绘制的ASCII文本项，包含文本内容、位置及尺寸信息。
*/
void CCGraphicWidget_drawAsciiTextItem(
CCDeviceHandler* device_handle,
CCGraphic_AsciiTextItem* item)
{
// 如果文本内容为空，直接返回，不进行绘制。
if(strcmp(item->sources_borrowed, "") == 0) {
return;
}
// 定义用于绘制的图像结构体。
CCGraphic_Image handle_draw_image;
// 初始化绘制的起始点为当前索引位置。
CCGraphic_Point draw_tl_point = item->indexed_point;
// 获取当前文本字体的尺寸（宽度和高度）。
const Ascii_Font_Size font_size = item->font_size;
const CCGraphic_Size size = __fetch_font_size(font_size);
const SizeBaseType font_width = size.width;
const SizeBaseType font_height = size.height;
// 计算文本绘制区域的有效右下角点（即绘制边界）。
CCGraphic_Point br = __pvt_fetch_valid_final_point(
device_handle, &(item->TexthandleSize), &(item->tl_point)
);
// 定义x方向和y方向的字符偏移量，用于逐字符定位绘制。
uint8_t offseterx = 0;
uint8_t offsetery = 0;
// 遍历文本中的每个字符并绘制。
for(uint8_t i = 0; item->sources_borrowed[i] != '\0'; i++) {
// 计算当前字符的绘制位置。
draw_tl_point.x = item->indexed_point.x + offseterx * font_width;
draw_tl_point.y = item->indexed_point.y + offsetery * font_height;
// 设置图像绘制的左上角点。
handle_draw_image.point = draw_tl_point;
// 绘制当前字符到目标设备上。
__pvt_draw_char_each(
device_handle,
&handle_draw_image,
item->sources_borrowed[i],
item->font_size
);
// 判断是否需要换行绘制。
if(__pvt_should_be_next_line(device_handle, &br, &draw_tl_point, font_size)) {
// 如果需要换行，将x偏移量归零，并增加y方向的行数。
offseterx = 0;
offsetery++;
// 重置x方向的起点位置为文本的左上角点。
item->indexed_point.x = item->tl_point.x;
} else {
// 否则继续绘制当前行的下一个字符。
offseterx++;
}
}
// 更新文本项的索引点位置为最后一个字符的右侧位置。
item->indexed_point = draw_tl_point;
item->indexed_point.x += font_width;
}更加方便的绘制
当然，还可以为了之后的组件方便生成一个返回绘制点的方便函数：
/**
* 绘制ASCII文本项，并返回绘制后的点。
* @param device_handle 设备句柄，用于控制绘制设备。
* @param item 要绘制的ASCII文本项，包含文本内容、位置及尺寸信息。
* @param method 文本追加方式，指示绘制后是否换行或连续追加。
* @return 绘制后的坐标点，表示下一个绘制位置。

CCGraphic_Point draw_tl_point = item->indexed_point;
// 获取字体尺寸。
const Ascii_Font_Size font_size = item->font_size;
const CCGraphic_Size size = __fetch_font_size(font_size);
const SizeBaseType font_width = size.width;
const SizeBaseType font_height = size.height;

const CCGraphic_Size size = __fetch_font_size(item->font_size);
draw_tl_point.y = item->indexed_point.y + size.height;
return draw_tl_point;
}为什么要给函数标记为inline
对于现代的编译器，inline只是起到了一种劝说的作用，他将调用转换为直接插入函数的汇编代码，节约了流水线刷新和代码跳转，这样来看，是一个不错的关键字，但是，一个过于庞大的函数标记为inline是一个无效的举措（几乎没有节约开销，所以编译器有的时候不会理睬，对于GCC，尝试使用force_inline标记符强制内联），现代的inline更加像是一种允许重复定义的关键字（因为他直接将汇编代码插入到了调用者上，符号直接被替换消失了）
