esp32s3 sdmmc 读写速度慢 Quote Postby低低低低级嵌入式软件工程师»Fri Oct 04, 2024 12:35 pm 我使用了idf中的sdmmc例程,使用了4线mmc读写协议,sd支持20MHZ,理论读写速度是10MB/S,但是实际读写速度只有200KB/s左右,sector size给的是512。我测试写sd卡的操作是,创建一个新的文件往里面写8KB左右的...
环境:IDF版本为5.1.1,使用的ESP32s3芯片,自己制作的PCB板子 1.使用sdmmc例程,引脚和默认配置相同,使用4线制,初始化时报了如下错误。我对了一下,连线没有错误,请问应该怎么解决呢? Code: Select all E (420) sdmmc_common: sdmmc_init_ocr: send_op_cond (1) returned 0x107 E (420) vfs_fat_sd...

Hi, I would like to use your logic analyzer for capturing CMD pin traffic of sdmmc interface. Is it possible to use CLK pin of sdmmc as clock source? sdmmc runs at 40 MHz in my case. The maximum sample frequency for esp32s3 is 80 mHz, you can see that there are signals, but...
Please install XIAO ESP32S3 or Sense on the expansion board, then connect the Oxygen Sensor to the A0/D0 interface on the expansion board with the Grove cable. Finally, connect the XIAO to the computer via USB-C cable. Software Implementation In the following program, we will use the ...
