      https://arstechnica.com/gadgets/2024/02/sd-express-cards-from-samsung-promise-faster-than-sata-speeds-for-microsd-devices/ Something to think about for a 4.1 successor.

      The duplicate libraries are a routine warning. They are not fatal, the program picks one from among the libraries it found and uses that. The fatal error is still just that it doesn't find ST_7789_t3.h in the places it expects. On my mac it...

      I think your problem is likely that you moved where the files are located and the code needs to know where to look. If you put files inside the src folder you'd need to change a line something like that.

      #include "src/Display.h" or something similar

      I recently found that a new 16GB card had come formatted FAT32 and I'd declared it on the T4.1 as exFAT. It wasn't recognized by the T4.1 until I initiallized it as exFAT on my Mac. It is probably still inherently slower (UHS 1 vs UHS 3) but I...

      Now I see the memory used stuff: /Users/raine001/Documents - MacBook Pro/Arduino/TeensyEyes_copy_20240205/audio.ino: In function 'void loopAudio()': /Users/raine001/Documents - MacBook Pro/Arduino/TeensyEyes_copy_20240205/audio.ino:103:12...

      The combinatorial calculation underestimates the size of the problem. It doesn't count RAM2-->RAM2 and doesn't take into account that RAM2-->EXTMEM and EXTMEM-->RAM2 are different because write speed != read speed.
    • J
      There are so many different use cases that I think you are going to have to carefully select what you want measured and likely do it yourself. The different segments of RAM have different speeds, RAM1 vs RAM2, ITCM vs DTCM. Most people are using...

      Again, what I'm seeing at the bottom tile of the arduino 2.2.1 window where it usually finishes with a list of amounts of memory used in various sections is the warning and then nothing below it. It does otherwise finish compiling and uploading...

      I will try to put it in the post today. I don't know if it will help, but it's easy to do. I found an ancient 1 gb usb stick.

      jrraines replied to the thread Teensyduino 1.59 Beta #5.
      I tried changing board type and back to teensy 4.1. It does compile, load and start running. It does not show the usual list of memory used in each section, just the error/warning messages -- the same ones, I think. In file included from...

      Does 59.5 use a different compiler version?

      jrraines replied to the thread Teensyduino 1.59 Beta #5.
      I tried 'save a copy' then compiling that (somehow I have to recreate the src folder and move everything that I'd put into it back in place). It compiles pretty quickly but I'd guess that means it is not re-using anything from before. Once again...

      Most of what I did to make Chris' codebase work on Arduino 2 IDE was to move a huge number of files into src/

      The program runs as expected with 1.58.1--the eyes move and sounds play for 12+hours. If I use just Serial.print statements those seem to print for at least hours. If I include Serial.printf, however, those quit working within 30 minutes; I'm...

      I have a modified version of Chris' Uncanny Eyes which compiles without errors on IDE 2 and 1.58.1 and gives this error on 0.59.5: In file included from /Users/raine001/Documents - MacBook Pro/Arduino/TeensyEyes/config.h:30...

      if you look at Chris' code (in config) you see: #ifdef USE_GC9A01A GC9A01A_Config eyeInfo[] = { // CS DC MOSI SCK RST ROT MIRROR USE_FB ASYNC {0, 2, 26, 27, 3, 0, true, true, true}, // Left display {10, 9, 11, 13, 8, 0...

      I tried googling GCC and section type conflict. I found explanations that I can't follow/seem to require more thorough understanding of GCC than us simple Arduino IDE types are ready for. Here I found this comment: " This question is an exact...

      I played around with the idea of FreeStack.h this might be accurate; the numbers seem sort of reasonable: // brief FreeStack() function. #if defined(__IMXRT1062__) extern unsigned long _edata; extern unsigned long _sbss; extern unsigned long...

      I have another question, trying to understand what is going on with the stack, I've found this (which generates appropriate numbers but a bunch of compiler warnings and only ratchets up as more and more of the words marked at setup are used) and...

      I checked it with the help menu on firefox: cleared cache and cookies for pjrc as they suggested and it is working now. Thanks for your feedback!

      I'm starting to play with this again. I started with Chris' github repository but made some minor changes so I could use Arduino 2 IDE. last year I gave up because of stuttery sound and recently posted a solution using PSRAM (as one big array)...

      Yesterday I posted wav2bin code. Today I played with it some more on my mac. On the mac, file names can have spaces and punctuation in them. I threw a bunch of files at it and realized that some of the names produced had extraneous trailing...

      I guess the other things my original post may not have made clear is that the ffmpeg commands convert all of the .mp3 or .m4a files in a single directory to .wav and likewise ./wav2bin (like wav2sketch does for .h and .cpp files) converts all the...

      What I used in the uncanny eyes is very much like what you see above. I have a separate audio.ino tab with a setupAudio() (without all the print statements above) and loopAudio() fcn. In the main uncanny eyes setup() I called setupAudio(). I did...

      Last year I was trying to play music while running Chris' uncanny eyes on a T4.1 and gave up because the sound was stuttery. I probably went wrong in not paying more attention to advice I got from smarter people here. This year I thought I'd...
