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. ...
Have a FAT Formatted SD Card connected to the SPI port of the ESP8266 The web root is the SD Card root folder File extensions with more than 3 charecters are not supported by the SD Library File Names longer than 8 charecters will be truncated by the SD library, so keep filenames shor...

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)...

Your example is writing one byte at a time. That won't get you an accurate idea of how the overall speed of writing to the SD card - your code will spend a disproportionate amount of time processing the individual writes. If you want to get a more accurate idea of how fast you can...
