2,sd_card.h,sd_card.c 这里就是实现sd卡的初始化,具体怎么弄参考前面的博客,然后里面还有一些esp32操作sd卡的函数,跟前面博客中读取sd卡差不多,应该很好理解,我也是复制的别人的。 #include"sd_card.h"boolSdCard::init() { SPIClass* sd_spi =newSPIClass(HSPI);//another SPIif(!SD.begin(15, *...
拍摄并保存照片将以下代码复制到您的Arduino IDE中: 该代码首先包括使用相机所需的库。我们还包括与microSD卡交互所需的库: #include "esp_camera.h" #include "Arduino.h" #include "FS.h" // SD Card ESP32 #include "SD_MMC.h" // SD Card ESP32 ...

I'm develop custom board with ESP32-D0WD. It uses sd card for loging information. Every time I'm trying to write to sd card i'm getting errors.Connection between MCU and sd card are same as on lyrat4.3: SD_CLK -> MTMS (Pin 17)...

I'm also sure to close the file with file.close() after reading it, so that I can later reopen it without a problem. But whenever I try doing it after calling smartdisplay_init(), the same problem happens. Even when using a exclusive SPI bus for the SD card. This is my board ...
