TEENSY 4.0 - PMF Player - SdFat version 2.0.0 BETA ONLY - 512k array buffer example. ;) //============================================================================ // PMF Player SdFat v2 BETA example. // //...

Yeah I was afraid of this. I am actually loading a big music data file in 512k buffer now, plays beautiful if the file is not too large for the destination array buffer. Funny part is it will play even if buffer is...

One more noob question: are you loading the music data from the SD card? The reason I'm asking is because I'm not sure if I can split the song data file and play it from let's say 126kb array buffer. :confused: Well...

Hi Jarkko. If it's not too much to ask can you explain the first few bytes of the data structure created with PMF converter. I'm not sure about the data marked in the red: 0x70 0x6d 0x66 0x78 - ASCII (p f m x<--? )...

Here is what I have you can probably modify it to suit your needs. #include <SdFat.h> // SdFat V "2.0.0" SdFat SD; File m_pSource; const int DIR_max = 250; // const int max_DIR_name_lenght = 255; char...

@ MichaelMeissner and JarkkoL. Thanks both of you I could not reply sooner because of power outages after snow storm ‘Ezekiel’ in the Poconos USA. @ MichaelMeissner Yeah I'm not sure what my issues are yet Perhaps...

Try digitalWriteFast. There is of course other caveats such as loop() overhead and pin slew rate limiting, which is on by default on teensy 3.x.

Behold my poor man's Teensy 4.0 microSD slot. ;) Digi-Key Part Number 609-5773-1-ND

Click me :D --> SPI Data in/out naming clarity

I am not sure about ratiometric but you can use these on Teensy 3.x void setup() { // put your setup code here, to run once: analogReference(EXTERNAL); // set analog reference to EXTERNAL-INTERNAL ref ...
