Help Please?

[brandon]

Ok so i know this is dumb but i am not sure if i just have to copy every code and paste it or if there is just one i need, so do you think you could post just all the code entirely for copy and pasting?

Thanks

Download the folder soundpod and open one the file "soundpod.ino" with Arduino IDE, all the necessary files will open along with it. You have to just compile and upload the code

[brandon]

Ok, Thank you so much!
Brandon

[brandon]

the code won't work correctly, when I attempt to compile the sketch there is always something that "isn't declared" or something such as that. could you just reply to this with the code by copy and paste it? because for whatever reason, it won't work correctly which is a pain since I really like the idea and even got custom PCBs printed

[Neutrino]

Can you send the error message or at least a screenshot of the problem?
Copy paste would make the problem worse. Just make sure you have installed all the library necessary (it's mentioned in the readme file) and compile.

I tried it again but I get the following error: 'flashPage' was not declared in this scope. I am new to all of this and I am not sure how to fix it. Please help.

The following is the code I am using:

You have only half the code.

Try these steps to compile and upload the code, don't copy paste

download git for windows

Then run this command to download the code
git clone https://github.com/Neutrino-1/Arduino-Soundpod.git

Finally open the "soundpod.ino" using arduino IDE (it's location : Arduino-Soundpod/soundpod/)
and the remaining files "AudioPlayer.ino" , "Input.ino", "display.ino", will open along with that.
compile and upload the code.

[brandon]

ok, thank you so much. I finally got the code to compile and just need it to upload to my pro mini. Thank you so much for helping me get this to work. When I finish it and older it to the custom PCB I have I'll add the photos to this.

[brandon]

Ok, now I cannot upload the code to the mini pro. May I ask you for help on this? If not then just say so and I will not bother you anymore about this, if so then this is the error message:

In Arduino IDE under "tools" make sure the following setting are set:

board : Arduino pro mini
Processor : Atmega328P 3.3v 8Mhz
port : Select the COM port where your board is connected

[Note : Check in windows device manager if your board is recognised in your PC]

[brandon]

Ok, it's just a faulty board. I have done everything correctly and I just need to order another board. Thank You for your help.
