    Thanks, I'm using LittleVGL for the menu system, it's really nice! And yes, because I pre-encode the video file, it's literally just a read directly into the memory buffer and then a SPI transfer of...

    This is entirely possible, and a library would be very useful I think!

    I'm currently getting 30+ FPS video and sound streamed from an SD card (SdFat Beta, SDIO, clock 70Khz) using a Teensy 4.0,...

    Just a quick reply - I have the Teensy 4.0 working fine with the SdFat beta, as have others it seems. It's been a while since I got it going, but I remember having to format the card as exFAT, and...

    It is printing the memory address, because you are assigning the memory address of buttonId as its value with buttonIdPtr = &buttonId; Try buttonIdPtr = buttonId instead, that works in your code....

    Thanks :) The Pacman code is currently a little too interwoven with my display/input code, and esp. coded to the rotation of the ILI9342 vs ILI9341, but yeah, after this project, I can separate and...

    I just want to give a +1 to LittlevGL. Currently using it on a Teensy 4.0 with an IL9342 based 2.3" display and XPT2046 touchscreen, and it's pretty straightforward to use and the results are...

    Update - this is the troublesome code snippet, it takes audio data (read from the SD card into videoAudioBuffer), and pushes it to an AudioPlayQueue

    I'm having fun, thanks for this, my sketch now has the headroom it needs (although the IDE still reports way more global variable space usage when I chose FLASH memory vs compiling on the Teensy...

    AudioPlayQueue memory issue?

    Have an issue using AudioPlayQueue on Teensy 4.0, that isn't present on Teensy 3.6. My sketch is complex, so will describe the issue seen as best I can in the hope it jogs some recollection or...
  12. AudioOutputI2S on Teensy 4.0 not working? Hair puller!

    Ok, went to simplest possible setup - Guitar example from the Audio library, taking TX, LRCLK and BCLK to Adafruit I2S 3W Class D Amplifier Breakout - MAX98357A.

    AudioOutputI2S works on T3.6 with...

    I second that emotion. If behavior is flipped significantly (from defaulting to flash unless FASTRUN, changed to RAM unless FLASHMEM) I'm an opt-in kinda guy, not opt-out (although from my first pass...

    Thank you for the response, but - the device with twice the flash and four times the RAM (4.0) cannot handle the exact same sketch as the 3.6?! I quickly went through my code and marked 90% of it...

    Trying to follow along with all this info about the Teensy 4.0 memory structure, but I have this oddity which I can't explain:
