I'm making a raspberry pi handheld gaming console. I'd like to use 5 face buttons, 2 triggers, 4 button D-pad, and an analog joystick. This would require 13 analog inputs. I'd also like to add 2 digital capacitive touch sensors as additional buttons.

I want to make sure I'm correctly reading the layout of the Teensy LC before I purchase the unit. According to: https://www.pjrc.com/teensy/teensyLC.html

and the "Various microprocessor layouts" spreadsheet: https://docs.google.com/spreadsheets...gid=1683806103

the Teensy LC has 13 analog inputs located at A0-A9 (Right Side), A10-A11 (Inside Right), and A12 (Back Pins). Since I'm only trying to use the capacitive touch sensors as on/off, rather than a range of voltages, I can wire them to any pin on the left side and program the Teensy as such.

Does this plan make sense? Is it just as easy to configure A10-A12 for analog input as it is with A0-A9? I've read a lot about microcontrollers, but I am totally new to all of this. Thank you in advance for any advice you can provide.
