Hello. I am still fairly new to teensy, as well as prototyping, so please forgive me for my lack of experience / understanding.
I am interested in using Teensy boards as the brains for my DIY Hardware MIDI control surfaces.
I am aware that the Teensy boards are great for this purpose for many reasons, including having a fair amount of GPIO pins to connect sensors to (sensors such as rotary encoders, potentiometers, buttons, ribbon controllers etc).
I have a teensy 4.1 (received in the post today).
I am now curious to learn how many of the GPIO pins I can use with internal interrupts.
I thought the Teensy 4.1 had 55 GPIO, however on the pin out I can not see all the GPIOs.
Perhaps I am not looking hard enough. Can someone tell me where the 34 - 41 GPIO's are? Perhaps its just me, but these pins don't appear to exist.
If pins 34 - 41 (8 pins) do not exist, then, does that mean that the Teensy 4.1 has 47 GPIO? And if so (either way)
how many of the GPIO pins can be used as internal interrupts?
Please help ;-)
Thanks for reading
