    Teensy 4.0 USB-MIDI host issue

    No, sorry. I gave up and used a Raspberry Pi (I had laying around) as my USB-MIDI host. I still have the Teensy 4.0 with the USB host port (and the troublesome synth), so I can try things if someone knowledgable has any idea, but I'm done looking on my own (I do not have the skills to solve...

    Teensy 4.0 USB-MIDI host issue

    So, I've worked around the issue for the moment, using a USB to MIDI cable (as the DIN input of the Crave is working fine), but I have run out of DIN MIDI plugs, so I would prefer to use the Crave over USB... If someone has any idea, I'd appreciate it. Would it be worthwhile to look at the USB...

    Teensy 4.0 USB-MIDI host issue

    After fiddling around, I found out that sending exactly 3 MIDI messages (simple NoteOn) to this synth is enough for the sketch to hang up. As long as I don't send anything to it, it continues to work fine. After I send MIDI messages to this problematic device, teensy sometimes keeps on receving...

    Teensy 4.0 USB-MIDI host issue

    Thank you for you help. In my case, Teensy is only a USB MIDI Host (using its second USB port through a breakout shield). Its first port (micro USB) is just a serial port. Using USBHost_t36, I read all events from the connected MIDIDevices on the host port. It's still highly possible there's...

    Teensy 4.0 USB-MIDI host issue

    I've been using a Teensy 4.0 as a USB-Midi "hub" (broadcasting MIDI messages to all connected devices over USB) for a few months, and it's been working great. However, I purchased a new synth recently, and for some reason the teensy crashes/freezes when this synth is connected. This new synth...

    Another Teensy 4.0 Breakout Board

    I received my boards yesterday, in 1.6mm. No apparent issue. I began soldering one today. I had to clean some copper burr, but it went smoothly after that. No trouble with the smallest castellations, a bit of flux paste made quick & easy work of them. I'm now stuck for the day as I can't...

    Another Teensy 4.0 Breakout Board

    Ordered in regular 1.6mm PCB. I'll keep this thread updated once I receive them to let you know how they turn out.

    Another Teensy 4.0 Breakout Board

    I've been looking at your breakout board for a week or so (along with the USB host companion board), waiting to finish a design of my own before ordering them all from OSH Park. Should I order it in 1.6mm, or are these also hit-and-miss ?

    Highly optimized ILI9341 (320x240 TFT color display) library

    Big thanks to both of you for your answers. My project is a fancy flight/racing sim button box, using the screens to display button labels, as well as some game-specific information if I can (tire temperature for a racing game, for instance). So far, I've been able to have 4 working displays...

    Highly optimized ILI9341 (320x240 TFT color display) library

    Hello, I have a question about a project using a Teensy 3.1, ILI9341 displays and the associated library. I hope this is the right place to ask. So, I was thinking about using a teensy to drive 5 ILI9341 screens. I initially thought it would be possible, since during my research on SPI, I had...
