以下是我的代码，是仿照https://platformio.org/lib/show/1559/TFT_eSPI/examples改写的代码，显示图片正常，但是一到载入字体，tft.loadFont(fileName, SD); 就报错重启
void setup()
{
Serial.begin(9600);
tft.init();
tft.setRotation(0);
tft.fillScreen(TFT_BLACK);
delay(500);
if (TFT_BL > 0) { // TFT_BL has been set in the TFT_eSPI library in the User Setup file TTGO_T_Display.h
pinMode(TFT_BL, OUTPUT); // Set backlight pin to output mode
digitalWrite(TFT_BL, HIGH);
// digitalWrite(TFT_BL, TFT_BACKLIGHT_ON); // Turn backlight on. TFT_BACKLIGHT_ON has been set in the TFT_eSPI library in the User Setup file TTGO_T_Display.h
}
//挂载文件系统
sdSPI.begin(SD_SCLK, SD_MISO, SD_MOSI, SD_CS);
if (!SD.begin(SD_CS, sdSPI))
{
DebugPrintln("存储卡挂载失败");
return;
}
tft.setTextWrap(true, true);
// Name of font file (library adds leading / and .vlw)
String fileName = "MicrosoftYaHeiUI-16";
tft.setTextColor(TFT_WHITE, TFT_BLACK);
tft.loadFont(fileName, SD); // Use font stored on SD
tft.setCursor(0, 0);
tft.setTextColor(TFT_WHITE, TFT_BLACK);
tft.println("测试!");
tft.unloadFont();
}
