Hey I'm very new to teensy with little indepth knowledge on how they work. I have been trying to connect a Wii nunchuk to my teensy 4.0 and intend to use it to control a strip of Neopixels. To read the wiichuk inputs I am using this library https://github.com/GabrielBianconi/arduino-nunchuk and as a test I am printing the outputs to the serial (the example script in the link). Initially I had no luck and the inputs to the controller were not being read (random numbers were being printed for inputs). I then changed the CPU speed from 600 MHz to 24 MHz which is closer to the CPU speed of the Arduino UNO (18MHz I think) which is the board I've seen most examples of the wiichuk being connected and this worked fine. My problem is that the Neopixels that I am using don't work at 24MHz but work at 600 MHz and I've read somewhere that messing with the timing of led strips is notoriously annoying and difficult. My question is then is there any way of getting the nunchuk controller to work at 600 MHz? I've attached a photo of my circuit set up (I've read that you need pull up resistors to make readings more reliable so I've added them in, but it works without them too at 24MHz) . I would be grateful for any help. Thank you!!
