  1. T3.6 - USB Host - Does it support game controllers?

    Are there any 'stable' (or mostly usable) libraries for the Teensy 3.6 that support reading USB joysticks such as the Dualshock 3/4 (Playstation) or X-Box controllers?

    The T3.6 Bluetooth thread...

    Thanks very much for the information.

    Are there any plans to change the way this works? It sounds like I'll need to edit this file every time I update the Teensy libraries?
  3. How can I enable USB Keyboard/Mouse/Serial but disable Joystick?

    I'm using the Arduino IDE but moving to PlatformIO. Regardless, the Arduino IDE provides different USB HID options for the Teensy boards.

    The best option for me is "USB...
  4. How can I turn on PC motherboard with Teensy 3.2? (measurements inside)

    I'm trying to connect a Teensy 3.2 to a PC motherboard to turn the PC on/off. The motherboard header is 2-pin (PWRBTN# and GND), like all PC motherboards.

    I'd also like to use a 2-pin Y-splitter...
  5. How can I convert a string of "KEY_A" to the Keyboard.h KEY_A define value?

    I'm building a project that accepts commands over RS232 and then sends a keystroke over USB HID using the Teensy 3.2.

    What is the most efficient way to accept any keystroke string and then convert...

    OK - So it sounds like the Teensy 2.0 is capable but just doesn't have the necessary software? Could I use something like NicoHID for these features? (regardless, I've ordered an extra Teensy 3.2...

    I have a couple of questions...

    1) Does anybody know why the "Teensy LC & 3.0 & 3.1 Only" support absolute positioning using the mouse library? I'm using a Teensy 2.0 and I see a third party...

    Enclosures for Teensy plus DB9 connector?

    Does anybody have any nice enclosures for building a USB-to-DB9 (Serial RS232) adapter? It's easy to buy the necessary parts and place them on a breadboard but is there something a little nicer I...
  9. What size PCB to fit on top of Teensy 3.2? Any enclosures available?

    I'd like to add an DB9 (RS232) port on top of the Teensy 3.2. Does anybody know if an empty "shield" kit is available, or what size PCB I would need to stick on the top of the Teensy?

    Also, are...
  10. OK - I'll give it a try. Thanks everybody

    OK - I'll give it a try. Thanks everybody
  11. RS232/Serial communication: Do I need DSR/DTR and CTS/RTS?

    I'm trying to build a console rollover cable to bluetooth adapter. (The ports on the back of networking equipment (routers, switches, etc) often have an RJ45 port to connect a rollover cable and...
  12. Does the Teensy 3.6 support multiple USB ports and/or software RS232?

    According to the specifications, the Teensy 3.6 has 2x USB. There is already one Micro-USB socket on the board but could I add a second socket?

    I'd like to connect the Teensy 3.6 to two different...

    Yeah, that's exactly what I was thinking about doing. Thank you so much for all of your help!

    OK - Thanks. The delay was only there to illustrate the problem. I was hoping to avoid the very slight drop to low but it sounds like its not possible.

    Thanks so much as always for the help!

    OK - I'll remove the resistor.

    I'm using a delay() between pinMode and digitalWrite to see what's happening so I'm not sure if this will cause a problem, but pinMode(WIZ_RESET_PIN, OUTPUT)...

    Thanks for the reply. I'm still having some problems though.

    Also, I've noticed my Wiz850io module has a built-in 4.7k pull-up resistor between RSTn and 3.3V. (according to the schematic).

  17. How can I default an output pin to high immediately when power is applied?

    Sorry for so many questions, but I'm learning a lot and reading datasheets, searching, etc, before I ask anything.

    Anyways, I'm connecting a Wiz850io to my Teensy 3.6. The Wiz850io has a reset...

    OK, let me make sure I understand correctly.

    I can use a single 1N5817 diode between VUSB and VIN, and it will always prefer my external power source even if USB and external are both 5v?

    Is...
  20. How to external power Teensy 3.6 and switch between USB power and external?

    From what I understand, I can connect a diode between VUSB and VIN (?) to have the Teensy automatically use the higher voltage (USB power vs external), but I'm planning to use a 5v external power...

    Thanks for the information Paul. I don't have a need for more than 4 sockets but I spent last night reading through the library code to better understand it. That's when I found the items I...
  22. Should I use Teensy Ethernet library or Ethernet2 with W5500/Wiz850io?

    It looks like the Teensy Ethernet library supports the W5500 chip but MAX_SOCK_NUM is only 4 instead of 8 which seems incorrect since the W5500 does support 8 sockets. It's also using the slower SPI...
  23. How to support multiple clients with Ethernet library? (re: Teensy 3.6 + Wiz850io)

    Does anybody have any advice to keep track of multiple Ethernet clients at the same time?

    For example, I'd like to create a multi-user telnet server which means I need to keep a separate buffer...

    I've posted over that Wiznet forum (http://wizwiki.net/forum/viewtopic.php?f=16&t=5931), but after re-reading the datasheet it says this:



    It sounds after you change the PIN back to high, you...
  25. If I understand the datasheet correctly, you only...

    If I understand the datasheet correctly, you only need to hold the pin low for 500 us (0.5ms) and then wait another 50ms for the board to reset. I'm thinking that instead of delay 1000 you only need...

    Ahhh, OK. Thanks! I missed the link on the page but I see it now.

    Anyways, if I don't have any other SPI devices I think the only useful parts of the adapter is the voltage resistor (which I can...

    OK - Thank you. I might have to order another Teensy 3.6 then just to make it easier.

    Can I ask one last question? What type of header pins are attached in this picture?

  30. Do I need the WIZ820io adapter for the Teensy 3.6 or can I connect WIZ850io directly?

    I've just received my WIZ850io network module and my "WIZ820io & Micro SD Card Adaptor" from PJRC with my Teensy 3.6.

    However, do I need to use the adapter to connect the WIZ850io module to the...

    OK - Thanks for the information.

    If I use the Bounce library, it looks like I still need to keep track of the previous state?

    I'm actually working on a similar project using a Teensy 3.6 and Bluetooth chip (RN-42).

    From what I understand, Teensy 3.6 operates at 3.3v which is the same as the RN-42 so you should just be...
