Hello, LCDs work on either/or. Both boards have access to LCD pins: https://beagleboard.org/Support/bone101 . That page will show you every available pinout.
Seth P.S. If you are looking to hardware pins to a LCD display or use the Cape headers on the Cape, either/or will work too. I know the Seeed BeagleBone Green (or BBG wireless) has some functionality that makes it so you have to encounter some /boot/uEnv.txt changes (commenting or vice versa) in that file. ... Since you have many peripherals dedicated to the am335x, I am sure you can figure out all sorts of stuff to do! Also, there is a config-pin program one can use to alter pin modes, e.g. config-pin p9.16 pwm and/or gpio for that specific pin. I also noticed overlays are just .dts and .dtbo files etched into time on the BBB family of boards. You can find more on that here: https://github.com/beagleboard/bb.org-overlays/tree/master/src/arm . On Monday, February 15, 2021 at 5:38:16 PM UTC-6 [email protected] wrote: > Thanks.
