500k的RAM,启动后剩下100k左右, 我试过40K的bin是完全没问题的.我手头没带PSRAM的esp32,不然可以试试.

lv_font_t * my_font; my_font = lv_font_load("A:NotoSans_38.bin"); if (my_font == NULL) { Serial.println("font load failed"); }else{ Serial.println("font load ok"); } /* Create simple label */ lv_obj_t *label = lv_label_create( lv_scr_act() ); lv_label_set_recolor(label, true); lv_label_set_text( lab...

不是SD卡. SPIFFS分区.

参考这个能显示汉字, https://hellobug.blog.csdn.net/article/details/119411924 显示很慢...... 1.字库.C修改: static uint8_t __g_font_buf[144]; static lv_fs_file_t font_f; static lv_fs_res_t font_res; static uint32_t font_resCount; static uint8_t fontisopen = 0; static uint8_t *__user_font_getdata(int offset,int size){ ...

@Xin888 等级不够没法回私信. 中文字库我也没成功. data放了一个43.2K的字库,结果esp32反复重启.

抱歉把Arduino的内容发在这个版块了. 在Arduino的示例中LITTLEFS_test.ino SPIFFS_Test.ino FFat_Test.ino已经测试成功, 并且使用ESP32 Sketch Data Upload 可以上传文件到对应的分区. 但是怎样在lv_conf.h中怎样配置这些选项 #define LV_USE_FS_STDIO '\0' /*Uses fopen, fread, etc*/ //#define LV_FS_STDIO_PATH "/home/john/" /*Set the working directory.
