为OLED屏添加GUI支持3：字库

为OLED屏添加GUI支持3：字库

本文博客链接:http://blog.****.net/jdh99,作者:jdh,转载请注明.

环境：

主机:WIN10

开发环境:MDK5.13

MCU:STM32F103

说明：

       GUI中有字库方能显示汉字。英文，数字等。英文数字等ASCII码128个字符保存显示easy。但汉字数万，假设不用字库芯片，用软件保存。则flash明显不够。所以仅仅加入须要显示的汉字。

       本GUI用的显示方法，能够easy的显示不同字体，不同字号的汉字和ASCII码。

源码及步骤：

1.用工具FontCvt.exe(emwin自带工具)选择须要的字体，字号。以及须要的字符(汉字。ASCII)并生成相应的.c文件

2.将此.c文件转换为指定格式。下面为微软雅黑20号字体的转换后源文件:

FHZ20.c

	uint8_t k = 0;
	uint8_t bit = 0;
	uint8_t num_valid_bit = 0;
	uint8_t num_valid_byte = 0;

//	//读取字体信息
//	font_type = font_read_type(font);
	//读取字符信息
	font_read(font,c,&font_type,(uint32_t *)&buf_pt);
	//buf_pt = buf;

	//有效位数
	num_valid_bit = font_type.width % 8;
	//有效字节数
	num_valid_byte = font_type.width / 8;
	for (i = 0;i < font_type.height;i++)
	{
		for (j = 0;j < num_valid_byte;j++)
		{
			for (k = 0;k < 8;k++)
			{
				bit = (*buf_pt >> (7 - k)) & 0x1;
				gui_interface_draw_pixel(x + j * 8 + k,y + i,bit);
			}
			buf_pt++;
		}
		for (k = 0;k < num_valid_bit;k++)
		{
