PCtoLCD2002 生成字模转换为字库 .h文件
打开字体取模软件PCtoLCD2002.exe，选项进行如下设置：
然后在下方打入需要取的汉字，点击生成字模，生成字模，存储字模的txt文件。
使用如下python代码, 将生成字模转换为字库的.h文件
txt与python文件放在同一目录下
# 说明：
# 每次生成字库的字数限制: 100及以内
# 取模字高/宽限制: 3-256
# 取模字高宽比任意

代码将生成Font.h与Function.h两个文件
Function.h中的函数可以在TFT屏幕上显示单个汉字
/*******************单个汉字显示****************/
void showMyFont(int32_t x, int32_t y, const char c[3], uint32_t color) {
for (int k = 0; k < 8; k++)// 根据字库的字数调节循环的次数
if (hanzi[k].Index[0] == c[0] && hanzi[k].Index[1] == c[1] && hanzi[k].Index[2] == c[2]) {
tft.drawBitmap(x, y, hanzi[k].hz_Id, hanzi[k].hz_width, hanzi[k].hz_heitht, color);
}
}
以下函数显示多个汉字
/*******************整句汉字显示****************/
//显示整句汉字，字库比较简单，上下、左右输出是在函数内实现

//x,y显示位置 str为输入字符串 mode 0为水平,1为竖直 enable_auto_change_line自动换行
