I don't know where you are, you have not put that information in when you registered for the PJRC forum, but the Adaptor card can be bought here for worldwide shipment.

Hey, so i used my phone at a wedding for the 1st time last night, despite the issues i was having. everything worked pretty will. only a few things i have issues with. 1 is my original problem where after i playback last message and hang up, it switches to recording mode instead of back to ready. 2nd thing i had a problem with last night was if someone listens picks up the phone but hangs up before the greeting ends, it won't go back to ready mode, so upon hang up, it will continue to record until someone else picks up the phone. which brings me to the 3rd thing, is there a way to limit recording size, lets say to 1 minute and it will automatically end the recording and go into ready mode with the phone in hand, AND STAY in ready mode when the phone is hung up? keep in mind, when i have the phone plugged into my laptop, issues 1 and 2 don't exit, the phone behaves properly. can anyone offer any insight?

Hi together, I'm trying to get this running...
I have a Teensy 3.6 (4.0/4.1 was not in stock...) with the audio shield.
I downloaded DD4WH´s code and tried to compile as said in the documentation, but I still get this error message:

In file included from C:\Program Files (x86)\Arduino\hardware\teensy\avr\libraries\Audio/Audio.h:129:0,
                 from C:\Users\Admin\Documents\audio-guestbook-main\audio-guestbook\audio-guestbook.ino:32:
C:\Program Files (x86)\Arduino\hardware\teensy\avr\libraries\Audio/play_serialflash_raw.h:33:25: fatal error: SerialFlash.h: No such file or directory
compilation terminated.
Fehler beim Kompilieren für das Board Teensy 3.6.

How can I Solve this? I installed everything like it's in the documentation.

Hello,

I was the same problem.

I find the missing data in this website. https://github.com/PaulStoffregen/

All is good after.

I badly need help. I followed all the steps and connected everything. Copy pasted the code (removed Teensy 4.1 part as I am using 4.0), compiled successfully, then nothing. Not even a beep.

Checked the serial monitor and it says "Unable to access the SD card" repeatedly. I understand that this is a printed message to check if there is an SD card. I don't know why it is stuck in this loop.

To check my SD Card, i ran File > Examples > MTP_Teensy > Simplified Examples. My SD card got detected but 0 gb. Not sure if this is purely an SD card problem but at least I should hear a beep, correct?

I have the same problem. Wiring and Pin Settings are correct. Any idea how to fix this? Teensy 4.0 with rev d Audio shield

Same problem too.

I use teensy 4.0 with audio shield REV D2. I changed too mi SD PIN to 10, 11,13 but the it's the same.

I have this line when I compile. I don't know what is it.

Edit: My problem was bad connexion all is ok now with my SD card. I have a problem with a bad audio quality with the micro but I will test other cable or soldering...
