STM32软件模拟iic驱动oled（显示汉字，图片）（二）

在上一篇介绍的软件模拟iic及iic源码后，今天来实现显示汉字与图片以及各个函数的介绍。

一.函数介绍及使用

1.显示字符

OLED_ShowStr(unsigned char x, unsigned char y, unsigned char ch[], unsigned char TextSize)

x，y(所在页数)为显示字符的初始坐标，ch[]为需要显示的字符串，直接“hello world”填入即可，TextSize为字号可以填入1与2，当填入1时，函数调用的为codetab.h中的6*8点阵数组，当填入2时调用的是8*16点阵数组。所谓6*8，8*16就是在oled上占格的大小，oled分辨率为64*128，所以在应用时要计算好格数，以免oled上显示不全

OLED_ShowStr(0,0,"safasf124",2);

2.显示汉字

OLED_ShowCN(unsigned char x, unsigned char y, unsigned char N)

x，y(所在页数)为字符的起始坐标，N为汉字的模在16*16点阵中的索引，每两行为一个索引。

OLED_ShowCN(49,0 ,6);
OLED_ShowCN(65, 0,7);
OLED_ShowCN(81,0 ,8);

3.显示BMP图片

OLED_DrawBMP(unsigned char x0,unsigned char y0,unsigned char x1,unsigned char y1,unsigned char BMP[])

x0，y0(所在页数)为起始点坐标，x1，y1(所在页数)为图片终点坐标，BMP[]为bmp图片模的数组。

unsigned char ssss[]=

OLED_DrawBMP(0,0,128,5, ssss);

二.汉字与图片的取模

1.汉字取模

以PCtoLCD2002为例

 设置如图所示，

然后在此处输入需要显示的字即可生成字模

在下方将会显示各个汉字对应的字模，将字模复制到16*16的点阵数组中利用索引引用即可显示

 2.BMP图片取模

使用Ima2Lcd，将图片导入，设置为水平扫描（其实不管怎样扫描都一样），因为oled分辨率为64*128，所以要设置最大宽度和高度不超过这两个值， 还要注意输出图像的大小（正下方有写），这个将作为输出图像的结束坐标。

导出图片之后，将图片在取模工具中打开，设置模式为图形模式，

然后将字模复制，在代码中定义图片的字模数组，调用函数即可。
