DFR1154 : Recording and Playing Audio DOESN'T WORK
AngryRobot 2025-04-05 22:07:27 1369 Views5 Replies The example that demonstrates the recording and playback functionality compiles (with ARDUINO IDE 2.3.5 and esp32 3.2.0 library installed : the lastest updates) but doesn't work : All I can hear is a double pop sound coming from the speaker. I bought two oh these modules and I have the same result.
I followed your instructions the best I can. Programs like LED Blinking and CameraWebServer works great but I can't get any sound from the module. I feel like it's coming from I2S and esp32 library.
Can I ask you what esp32 library was used for the code examples? I spent countless hours trying and alaways end up with the same result, please can I get some help.
I can't add the tag properly for this topic but here is the ref : DFR1154 aka the new DFRobot ESP32S3 AI Camera module.
Try downgrading the ESP32 Arduino core to v2.0.11 instead of v3.2.0.
Many I2S-based libraries haven't been updated/tested with the newer ESP32-S3 support in 3.x yet.
ahsrab.rifat SOLVED : One of my modules was defectuous. The other one works well with the sound.
AngryRobot Thanks for your help!
1/ Nothing appears on the serial port print. But if I add a little delay just after : Serial.Begin(115200); I can see “start REC” on the serial port print. But I still get the same result: the LED lights up for 5 seconds then only a double pop coming out of the speaker
2/ The LED lights up for 5 seconds and then turns off, as it is supposed to.
AngryRobot Is there any serial port print when you run the sample code? 3/ What is the LED indicator status?
erhahaha Thanks for your help!
