FTP服务器运行在ESP-12E上,我们可以通过这个FTP服务器跟SD卡进行数据推送与获取。 第6步:挑战FTP库 我没有找到一个非常活跃的或者专门为ESP8266开发的FTP库。但是经过一番挖掘,我遇到了David Paiva,他将一个Arduino版本的FTP服务器移植到ESP8266,可惜它只支持SPIFFS,不支持SD卡。 终于功夫不负有心人,我发现有人...

参照示例recorder/element_wav_amr_sdcard及recorder/element_cb_sdcard_amr, 为了实现流模拟,通过(fopen,fread)读取sdcard文件数据流,并写入ringbuf1中,定义为ringbuf1的输入,将输出定义为decoder的输入。具体流程如下: [sdcard] --> FILE --> mp3_decoder --> fatfs_stream_writer --> [sdcard] 相应的测...

When you have done with your photo session, power down the ESP32-CAM board and remove the MicroSD card. Now transfer the card to a computer with a MicroSD card reader, and open up the file management utility to take a look at it. You should see the image files. Open them with the...
I just added example that is using USB device peripheral on S2 together with sd card (SPI). As the result we have simply sd card reader: https://github.com/chegewara/EspTinyUSB ... les/sd_msc With small amount of code it can be used to OTA update S2 with drag n drop. Example ...
https://github.com/espressif/esp-adf/blob/master/examples/recorder/pipeline_wav_sdcard/main/record_wav_sdcard_example.c 楼主看下这个sdcard 录音demo,更简单一点,可以跟进源码看下 这个也一样,看不出来代码是怎么获得pcm数据,我说的是pcm数据,我说的是pcm数据,我说的是pcm数据?录音的的数据放在什么变量...
My first ESP32 project. I'm trying to make a basic audio player that plays the Wav files from a SD card reader strait to a speaker. All the examples I'm finding seem to be using an external DAC. I know this is needed for mp3's, but didn't think so for Wav files. ...
In this article, we’ll discuss how to interface an SD or MicroSD card reader with ESP32. With these cards, 4 to 128 GB of storage can be added to the embedded system. The sensor data or other data is logged into plain text files on the SD/MicroSD card. Most of the SD or Micro...
braries/SD I have a kind of Mode 1 SPI Sensor on HSPI which does not accept other devices on the same bus. I want to use both SPI (sensor and sdcard reader) with this method: https://github.com/espressif/arduino-es ... _Buses.ino Sorry for this probably easy question, but Im ...
