打開字體取模軟件PCtoLCD2002.exe，選項進行如下設置：

然后在下方打入需要取的漢字，點擊生成字模，生成字模，存儲字模的txt文件。

使用如下python代碼, 將生成字模轉換為字庫的.h文件
txt與python文件放在同一目錄下

代碼將生成Font.h與Function.h兩個文件
Function.h中的函數可以在TFT屏幕上顯示單個漢字

/*******************單個漢字顯示****************/ void showMyFont(int32_t x, int32_t y, const char c[3], uint32_t color) {for (int k = 0; k < 8; k++)// 根據字庫的字數調節循環的次數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);} }

以下函數顯示多個漢字

/*******************整句漢字顯示****************/ //顯示整句漢字，字庫比較簡單，上下、左右輸出是在函數內實現 //參數說明: //x,y顯示位置 str為輸入字符串 mode 0為水平,1為豎直 enable_auto_change_line自動換行 void showMyFonts(int32_t x, int32_t y, const char str[], uint32_t color, char mode, bool enable_auto_change_line) {int x0 = x;int y0 = y;if (mode == 0) {for (int i = 0; i < strlen(str); i += 3) {if (enable_auto_change_line) {if (x0 + hanzi[0].hz_width >= TFT_WIDTH) {x0 = 0;y0 = y0 + hanzi[0].hz_heitht;}}showMyFont(x0, y0, str + i, color);x0 += hanzi[0].hz_width;}}if (mode == 1) {for (int i = 0; i < strlen(str); i += 3) {if (enable_auto_change_line) {if (y0 + hanzi[0].hz_heitht >= TFT_HEIGHT) {y0 = 0;x0 = x0 + hanzi[0].hz_width;}}showMyFont(x0, y0, str + i, color);y0 += hanzi[0].hz_heitht;}} }
