    Great that it worked. Please share in the forum some pictures of your TFT working, for me it is feedback, since I can indirectly see how the library works in other variants of EVEx and it allows me to improve the library. A while ago I tried to...

    MarkT replied to the thread Teensy 4.1 Inputs and Outputs.
    Do you mean the audio adapter? That has one microphone input, but two two line inputs. There are other options for interfacing to microphones, and yes that would be a separate board - any I2S compatible audio chip pretty much can work. Or you...

    Wonder of wonders... in the act of trying to pare down a 1200 line program to something I could present here, I had some lucky guesses. I apologize for not posted some code for you to at least get an idea, because I realize it's almost...

    Having just fallen down the Eurorack rabbit hole ( acquiring parts, building related stuff ) I am waiting to pounce when it is ready to be pounced upon.

    Quick note, I did another update of the branch mentioned above. I think I integrated the IRQ code and it might be working. However there appears like there might not be any current test sketches that calls the functions like...

    Yes, bridge the center to the pad near the other USB to power it from the 5V supply, or to the other pad to power it from the PD chip (which requires external power).

    A thousand thanks, TFTLCDCyg! I tried the code and it works! If I wanted to use an FT812 display with 800x480 resolution do I have to change something at the library level?
  • KurtE
    I think there may be something else maybe going wrong... That is the ILI9341_t3 library does still define those colors. From the latest Teensyduino, I see the header file still has: // Color definitions #define ILI9341_BLACK 0x0000...

    Hi there. I have a module and I want to connect it to my teensy 4.0 host to its USB, and send/receive data (for example with bulk transfer) at low level. Somehow this transmission of data is not being done, I don't know why. What do I need to do...

    Hi all, Pulled out an older project to resurrect it (update it really), and while it runs on the device, the program won't compile any longer. Teensy 3.2 and Adafruit LCD with ILI9431. If I remember correctly, I was using Arduino 1.8.(teens)...

    The library already includes all the instructions to access the teensy 4.1 SDIO reader. It is not necessary to define anything externally. Using GDSTx and the most recent SDFat library, the example to load an image from a microSD card installed...

    A couple of questions: - you say that you changed the month . . . how ?? - is your 3V coin battery attached to the GND & VBAT pins ?? Normally, to "save" the current time values to the RTC, a call to the Teensy3Clock.set(time_now); function...

    Looks like a wonderful project! Is there a reason to use the Teensy 4.1? Wouldn't the 4.0 be sufficient? Seems that there a some more pins you could use which are covered mechanically by the audio board. For the encoder it could be helpful to...

    You need to get knobs on those pots! Watch out for loose wires if you remain with it breadboarded - a more permanent construction will pay off the first time it gets dropped perhaps! I suspect your volume issue is the pots are linear and you...
