sdcard interface.PNG Hello, I am using the sd_card example with the Wrover dev kit and our target hardware. I can run the wrover kit in SDMMC mode or in SPI mode with no issues. App mounts the card, creates the file, renames the file, etc as expected. ...

Hello, Is there any example of a running ESP32-S3 with an SDIO SD card as a mass storage device? I tried to look for Adafruit TinyUSB https://github.com/adafruit/Adafruit_TinyUSB_Arduino but it seems that it doesn't support SDIO....
esp32-智能语音-mp3(sdcard) 由于官方example为针对Esp32_LYRAT开发板的,因此底层需根据板子IO进行重定义:(后续案例使用该定义文件) 官方由于使用menuconfig配置对应V4.2或V4.3的板子驱动,因此根据板子也进行了板层驱动定义: 1.esp-adf\components\audio_hal目录下,Kconfig.projbuild:(添加ESP_LYRAT_LLW变量)...
评估板做了个micro SD卡的接口,方便直接插到带卡槽的开发板上进行调试。 ESP32C3的SPI接口是硬件SPI,支持DMA,速度应该还可以,但是我用杜邦线连接的,肯定会影响信号质量,估计时钟很难跑到50MHz了。 接线: 编写测试程序: /* SD card and FAT filesystem example. ...
