    Future Teensy features & pinout

    Paul, do not underestimate how much trust and goodwill being open with your customers can generate. You're right too. I keep looking for a TeensyLC replacement, but really all of my projects that use it will use the 4.0 just fine. It is absurd overkill for a keyboard and joystick controller...

    Future Teensy features & pinout

    Well, I would consider the 4.1 to be a replacement for the 3.6. The 3.5 has access to more GPIO pins than either, but my use was an edge case. I've only built three copies of that project. If you look at the PJRC store, you'll see some 'real talk' about how the entire 90nm process is spooling...

    Future Teensy features & pinout

    I hope this is the correct place to post this. What I need is a replacement for the TeensyLC. I have quite a few projects that do not need high end processing, but make heavy use of Paul's USB drivers such as 'keyboard' and 'joystick'. The Teensy 4.0 will do the job, but it would be nice to...

    Teensy Series Vin (MAX)?

    I want to say that is good advice, but doesn't line regulation on a 7805 not kick in until 7 volts input? I've never actually tried to use a linear voltage regulator that far below its rated input. Good point for the on-Teensy passives. 6v is a fairly normal rating for capacitors, so maybe...

    Teensy Series Vin (MAX)?

    I am starting a design that needs to run on a very unregulated power supply. Arcade systems for those that are interested. Voltage can vary quite a bit, so it would be good if the microcontroller could survive 5.4v or more. Since PJRC does not provide this directly, is it correct to use the...

    Keyboard + Mouse + Joystick showing as multiple joysticks [w' workaround]

    There are no shortage of posts about Linux/RetroPie/Retroarch/Emulationstation seeing the Teensy as multiple joysticks when using "Keyboard + Mouse + Joystick". It turns out that somehow the Linux OS is recognizing the keyboard and the mouse as also being joysticks and assigns js* handlers to...

    Can USB Mode be joystick only? showing up as multiple devices.

    There are several entries in usb_desc.h that are not in the GUI. I assume there is another place to modify the GUI list. I'm in the middle of the same problem as you. I can confirm that two TeensyLC configured as "keyboard/mouse/joystick" show up as 4 inputs, with input 0 and input 2 being...
