    So this would be a very simplified flow diagram of how you could allow for syncing your teensy state with your game state.16334

    Awesome in that case here's what I would do as an example.

    Create a class "eddi message send" that handles everything required to send the messages to your game api. Then in your loop do a check...

    What you want to achieve is absolutely doable and I understand where you're coming from in order to sync your game and teensy state.

    As a "non programmer" it may help you to consider drawing some...

    My understanding (very limited) is that a joystick will appear as a "HID" device. I believe it's possible to have both HID + Serial with the teensy but there should be other guides available in the...

    I would say starting with 5 LEDs and 5 buttons to interface with EDDI would probably be a good starting point. Even just getting 5 buttons to change 5 leds on the teensy locally would be a very...

    Your lack of replies is probably due to the broadness of your questions. It's hard to tell how complex your setup will be. For example, 5 buttons and 5 LEDs? Teensy can handle that no problem. 20...

    Did you solve your issue?

    I'm slightly confused with your approach to this. You are using an interrupt to catch every pulse from the sensor and recomputing the time between pulses during the...

    So it seems you've had grounding issues with the boards. I couldn't understand why the PCA would blow your arduino. It seems your setup is far more complicated than your initial post hinted to.

    I'm concerned that on its own the pca9685 is blowing your nanos regulator without anything else connected as I'm looking to use the PCA9685 in my own projects.

    If you only connect the nano and the pca9685 together does it cause failure?

    According to your diagrams the nano is receiving 12V input to the Vin pin? - this is fine
    5v output from nano is being...

    They're pretty self explanatory and I used them with a 3v3 mico and 24v motor driver.

    I'm not completely clued-up on the teensy programming logic. Obviously something is causing your teensy to go into bootloader mode. This can be done a number of ways;

    Personally I think your 3v3-prog situation is a red herring. Again, the teensy is very robust in it's own right. I believe it's far more likely to be your power usage/motor draw causing issues on the...

    Dead Custom Teensy - Help me find why?

    That's exactly the kind of thing i was thinking. Probably really useful for folks new to teensy to see that when you use certain functionalities it can have knock-on effects.
