打开IDE ► 单击文件 ► 单击示例 ► 选择 SD ► 打开 ReadWrite 为了您的简单起见,我们在这里提供了相同的代码。 使用ESP32 写入和读取 MicroSD 卡的代码 /* https://www.electronicwings.com/ SD Card Interface code for ESP32 SPI Pins of ESP32 SD card as follows: CS = 5; MOSI = 23; ...
这里主要是在lv_fs_fatfs.c文件下的fs_init函数内进行文件系统的初始化,调用我们在sdspi库内建立的sdCard_Init函数即可,当然相应的也需要加入头文件 #include "sdspi.h"。 3.2.3 修改lv_fs_if.h /*File system interface*/ #define LV_USE_FS_IF 1 #if LV_USE_FS_IF # define LV_FS_IF_FATFS 'S...
The micro- SD Card Module is a simple solution for transferring data to and from a standard SD card. This module has SPI interface which is compatible with any SD card and it uses a 5V power supply because it has an internal 3.3V regulator which is compatible with ESP32. SD Card Module...
1、MicroSD 卡的说明 之前的帖子中已经对 SD 卡在 ESP32 运行的速度进行测试,ESP32 读取 SD 卡的速度只能达到每秒 2MB 左右。MicroSD 被评为四种级,可以满足要求。更快的卡无助于提高性能。 具体可查看另一个项目。 https://www.instructables.com/Select-SD-Interface-for-ESP32/ ...
前面的博客使用了第一种方式,然后也将C数组存储在sd卡,然后读取sd数据,构建lv_img_dsc_t结构体来进行描述。但是可能是构建的数据不对,或者 lvgl不太兼容这种方式,显示效果不好,图片有很多噪点,所以想了想,当图片数据在sd卡上时,还是的用第二种方式。
官方源码(esp-adf\examples\player\pipeline_sdcard_mp3),sdcard使用1线SDIO模式,所以只用到D0数据线(需外部上拉电路),(由于硬件D0线与GPIO2(strapping)共用,由于下载模式时,该电位需为低电平,所以与sdcard驱动有冲突,需注意)。 固件下载后,需要准备一张sdcard,并在sdcard根目录拷贝一个test.mp3文件。

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)...
