Hi all, im trying to make a audio guestbook for my wedding next week. I have everything wired up correctly in the phone, and am stuck on the coding part. Using teensy 4.0 and arduino 1.8
Here is my code followed by the errors:
Here is the errors: Im completely lost on what to do. Please help!!!
Arduino: 1.8.19 (Windows 10), TD: 1.56, Board: "Teensy 4.0, Serial, 600 MHz, Faster, US English"
Here is my code followed by the errors:
Code:
void setup() {
// put your setup code here, to run once:

void loop() {

}/**
* Audio Guestbook, Copyright (c) 2022 Playful Technology
*
* Tested using a Teensy 4.0 with Teensy Audio Shield, although should work
* with minor modifications on other similar hardware
*
* When handset is lifted, a pre-recorded greeting message is played, followed by a tone.
* Then, recording starts, and continues until the handset is replaced.
* Playback button allows all messages currently saved on SD card through earpiece
*
* Files are saved on SD card as 44.1kHz, 16-bit, mono signed integer RAW audio format
* These can be loaded directly into Audacity ([url]https://www.audacityteam.org/[/url]). Or else, converted to WAV/MP3 format using SOX ([url]https://sourceforge.net/projects/sox/[/url])
*

// To ensure the correct libraries are used when targetting Teensy platform in Arduino IDE, go File->Preferences and change the sketchbook location to avoid conflicts with Arduino libraries.
