    I just want to make sure that you'd considered soldering on a flash memory chip? That's how I'm attempting to solve my similar problem, althoughI still haven't been able to get it to work. From what I heard, data...

    Holy cow, such a relief! To sum up for anyone coming here in the future, 1) triple check your soldering, 2) make sure that you also clean it up / re-flow, &c. and 3) also be sure to include the startup code for any...

    So, I've wired Pin 9 to the T_CS pin on the touchscreen, and pin 14 to the display CS pin. I'm sorry if this is a dumb question, but when I run EraseEverything I haven't actually done anything with those pins—they...

    Ok, reflowing and cleaning worked wonders! If I've learned nothing else from this, "the final 'cleaning' step can be the critical part for proper function even if all else done well" is a great takeaway, thank you! ...

    Specs: Teensy 4.0 with Audio shield Rev D and a W25Q126JVSIQ-ND memory chip from digi-key. I am still struggling to get this working; just about the last piece of my puzzle. I was getting Erase Everything to work,...

    Unfortunately, there is apparently still some conflict with the T_DO pin, and the flash chip, because when I connect the touchscreen it can no longer access the flash card. Is there a way to disable the touchscreen...

    Yes, you're absolutely right, of course. Well, that explains why there wasn't a conflict with the screen display CS being on pin 14!

    Dionysus replied to a thread Flash Memory help in Audio Projects
    The touchscreen is using pin 8 as it's CS pin for touch detection and pin 14 for the display. Pin 14 is also the SCK for the audio board SD card, but that doesn't seem to be causing any problems (which is to say, when I...

    Thank you all for the help! It turns out that solder braid is a thing—who knew?!—and that helped me clean up my soldering enormously and, I think, fixed that problem. However, whenever I plug in my touchscreen it is...

    Sounds good, I will give all of that a try! This is from digikey, as well, so that's probably good. As I say, this is the first time I've soldered anything like this, so I'm not too surprised. Thanks!

    Well, shoot, that's not working for me. The only difference is that I'm using the teensy loader 1.51, but I can't imagine that *that's* my problem. EraseEverything did not return "Unable to access SPI Flash Chip", but...

    Good afternoon! I'm using a Teensy 4.0 with the Audio shield (rev D) and I've just tried to attach a W25Q128JVSIQ-ND flash memory chip. This was unlike any soldering I've ever done before, so I'm quite willing to...

    Oh, that's great, thank you! Always nice when adding two lines of code Just Works. If I can figure out the rest of it, it looks like I could use it for its intended purpose, as well. (:

    Ugh, you're totally right. Which explains why I wasn't worried about a conflict on 14 when I initially moved that pin. But it did work with those incorrect pin assignments! Either that, or I've gone completely mad,...

    In November of 2018 there was a post about an SPI conflict between the audio sheild and the touchscreen. Has anything changed since then? It sounds like folks are getting touchscreens to work with the audio board,...

    Got it! Must be obvious to most of the folks here, but I'm still so new at this. From this post: So instead of using 10 for the screen, I just moved it to pin 14. Thanks again!!

    Yes, layering multiple sounds is the goal here—polyphonic drums. In the ideal world I'm sure eight wave files playing all at once is more than enough—I doubt my ears could differentiate that many sounds! Realistically,...

    It occurs to me that an easier way to phrase this would be to ask if there's a simple way to implement wav2sketch on the fly. So if just reads in the data from the SD card, sticks it in a giant const unsigned int or...

    Yes, that's exactly what I was hoping for, thank you! It didn't magically let me play a thousand wav files all at once, but it's definitely a better way to handle things.

    I see that, but I will often need to play the files at the same time. I do appreciate that there are limits to how many audio files I can play simultaneously. Actually, according to some older posts it looks like that...
