    Teensy 4.1 USB Host issues

    Mouse objects depend on HID Parser objects. Have you tried the example sketches like: Mouse? Maybe try: #include "USBHost_t36.h" USBHost usb_host; MouseController mouse(usb_host); USBHIDParser hid1(myusb); USBHIDParser hid2(myusb); void setup() { Serial.begin(115200)...

    How to wire keyboard controller board (four usb wires 5V, d+, d-, gnd) onto Teensy for usb input?

    If you look at the T4.1 card, it is pretty easy to hook up both USB Host and USB Device. The Device pins duplicate what is in the USB connector that you connect up to your PC. So yes you can connect up the keyboard to the teensy using the host pins, and you can connect wires up to the Teensy...

    I will try to get back to trying it on this board. Sort of a PIA at times to hook up all of the wires in a secure enough way. So I much easier playing using the other boards. Did find using my camera shifter boards I did during the T4.1 stuff is coming in handy as it could plug into the...

    🤔I have not seen the problem of using the 8MBtye SDRam on the GIGA for the camera to read into. But when I looked at their schematic their SDRam setup looks very different than what I believe you are doing on these dev boards. That is they are using 12 address pins and 16 data pins to talk...

    Having a heck of a time getting a TFT w/ ST7735 to even compile

    Keeping fingers crossed it works for you. As the tutorial you linked to shows (retired). I believe that library is no longer updated and probably had a really old version of Adafruit_gfx as part of it.

    Teensy 3.6/4.1 USB Support for CCID USB Card Readers

    As far as I can tell, the only real changes they made to their version is to add unicode support... My fork of it with LLA support does not have that, but works fine for me so far with my HLA, which works for me to filter the data down to what I typically look at.

    Sounds good, I would suggest that you might make the changes and try it out. And then if appropriate create a Pull Request into core and see if/when Paul will pull it in. But still need the same stuff as we mentioned for DMA buffers aligned to 32 byte boundaries.

    Call to arms | Teensy + SDRAM = true

    FWIW - I believe we should use the KISS strategy and in this case change as few system things as possible. That is with EXTMEM or others who may use the sm_malloc code, I would probably avoid making changes to the underlying sm_malloc. Especially for example with extmem_malloc, which if it...

    I decided since I saw the Unexpected EOF on one of my board updates yesterday, to create an Arduino forum thread: https://forum.arduino.cc/t/arduino-2-3-0-unexpected-eof/1221459 As maybe there is an issue they need to be aware of.
