I am using terasic sd card example code playing audio through sd card(taking reference). So there is a function: bool SD_WriteBlock512(DISK_HANDLE DiskHandle, alt_u32 PysicalSelector, alt_u8 szBuf[512]){ return SDLIB_WriteBlock512(PysicalSelecto...
摘要: 如果大家使用较新版本的SDK,比如Android 1.6版本SDK那么在写入SD卡时需要加入WRITE_EXTERNAL_STORAGE权限许可,我们在androidmanifest.xml文件中加入下面这句<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"> 如果大家使用较新版本的SDK,比如Android 1.6版本SDK那么在写入SD卡时需要加入...
前一篇博客中介绍了Android6.0运行时权限简介,最近遇到这么一个情况,就是一个App以前都是在SD卡根目录直接新建了一个XXX/image/目录,来保存图片缓存的,但是如果适配到Android6.0,我们就需要弹出对话框给用户,来申请WRITE_EXTERNAL_STORAGE权限,如果仅仅是缓存图片为了提高加载速度,对于一个小白用户来讲,好像并不是什么...

I just benchmarked the write speed to an SD card and found out that it caps at about 400kB/s. I was surprised of such a low speed and read posts where users claim writing speeds of more than 1MB/s (up to 9MB/s) while others have speeds comparable to mine but could not figure ...

But I wrote a program to test the writing speed and was frustrated to find that the write speed was 4Mbps, which is much slower. So I want to know the benchmark of esp32-s3 sdmmc write speed. Here is my environment: esp-idf version : 5.0.2 ...
