在PIO主页新建项目spi_sdcard,框架选择libopencm3,开发板选择 MonkeyPi_STM32_G070RB; 新建完成后在src目录新建主程序文件main.c; 然后更改项目文件platformio.ini的烧写和调试方式:1upload_protocol = cmsis-dap 2debug_tool = cmsis-dap 2 编写程序

DigitalMemoryCard),完全兼容MMC标准。 (3)SDIO:(SecureDigital Input and OutputCard)安全数字输入输出卡。SDIO是在SD标准上定义了一种外设接口,通过SD的I/O 接脚来连接外围设备,并且通过SD上的I/O数据接位与这些外围设备进行数据传输。2、 工作模式工作模式是针对主机控制器来说的,SDI 控制器可以在符合MMC的 ...
接口:符合标准SD Specification Version 2.0规范,包括1-I/O和4-I/O两种模式。 默认模式:在默认模式下,时钟频率可变范围为0-25 MHz,接口速度高达12.5 MB/sec(使用4条并行数据线路)。 高速模式:在高速模式下,时钟频率可变范围为0-50 MHz,接口速度高达25 MB/sec(使用4条并行数据线路)。 对照: 下面是SD NAND芯...

For 2KHz, 4KHz and 8KHz logging (kind of pointless to get slower cards than these as the price is very competitive):https://amzn.to/3VQAUnt For 16KHz logging:https://amzn.to/3F4o7qR You will need an SD card with decent write speed forBlackbox logging. Betaflight firmware requires ...
主要参考esp idf自带的示例Espressif\frameworks\esp-idf-v5.0.4\examples\storage\sd_card\sdmmc。 在esp-who\examples\human_face_detection\terminal的基础上修改下面几处: (1)esp-who\examples\human_face_detection\terminal\main\app_main.cpp,在主函数中将sd卡挂载到系统中。
Card Detect is optional. Some SD card sockets have no provision for it. Even if it is provided by the hardware, if you have no requirement for it you can skip it and save a Pico I/O pin. You can choose to use none, either or both of the Pico's SPIs. ...
