    @ houston, @ jcugnoni I just tried out the above posted arrays with the waveshaper and audio shield and like them very much. Thank you. Fwiw I got a non-halting error message about the const, once changed to...

    Noted, great, and much gratitude @mjs513! The device I built one of those displays into was originally run with a mega2560, and despite using parallel mode, redraws were agonizingly slow. In contrast the kludge it's...

    The graphicstest sketch compiles for me for teensy 3.5. I'll try this library next time I do any thing to the device.

    Yes, I have one of these in a project using a Teensy 3.5 I'm actually using the Adafruit_ili9341 library with it, modifying the Adafruit_ILI9341.h file to the proper resolution... it actually works despite the...

    while (!Serial) ( I think it's relatively safe to comment out that whole line it's there to halt execution until you open the serial monitor)

    I'm not sure but it may be that something in between is taking processor time, possibly in the sensor library, which is trying to provide service to all potential uses. You might have better results in writing...

    That's done in the initialization of the wire library, which in this case that's happening in the adafruit library. Looking into that, I'm not *seeing* a call to 400khz for the wire library... This is done by...

    I have read your code. I have read the datasheet for the sensor. Once again, the audio shield is playing what you are sending it. What you are sending it may not be what you wish for it to be. There are...

    The digital output of the sensor is not audio data. The audio shield is attempting to convert data that is no longer analogous to a pickup. This is why you are hearing a "metallic" noise.

    I believe I understand what you're trying to do. From your configuration information I assume the output you are getting from the accelerometer is analog and being received by the ADC1 object. Based on your...

    I'm having some difficulty understanding how accelerometer data should be audio. Can you explain this? Weird sound makes sense, if data that is not audio is run through digital to analog conversion, the result is...

    I decided I wanted to try a breakout on a project so I went ahead and did this much assembly...no CAN bus parts, no pull ups. I used solder paste and a heat gun. Small bits of copper tape were used to hold down the...

    The question seems clear. The functionality this user is concerned with is 4 posts above. It is USB audio for the Teensy 4, a model getting plenty of press in "maker circles" about its speed and capability, but...

    Oh yeah, lots of noise out there in regards to ESP32. Wear waders. I like the dual core possibilities. For the most part, the arduino core is very much the same for the gazillion variant boards. When in doubt, choose...

    I'm no expert, but after some trial I set the temp to 20 degrees c above the solder paste temp and leave the flow low. Remains to be seen if I'll damage the gun that way, the temp is at the low end of the gun's range...

    I'm waiting to test your assembly instructions. I'll be using a preheater and heat gun to solder the surface mount stuff. If you happen to have pre-printing data available, that will work just fine.
