Our #BL604 GPIO Expander for #NuttX RTOS will configure the GPIO Interrupts: Rising Edge Trigger vs Falling Edge Trigger

https://github.com/lupyuen/bl602_expander#set-gpio-options

@Ralim Hmmm major Kconfig Conflict between BL602 and ESP32 ... Wonder how the NuttX folks feel about this 🤔

Our Grand Plan for syncing and testing Apache #NuttX RTOS on #PineDio Stack #BL604 ... Getting complicated 🤔

https://lupyuen.github.io/articles/pinedio2?88#automated-testing

At #NuttX Startup, our #BL604 GPIO Expander configures each Input / Output / Interrupt GPIO ... And registers the GPIOs as "/dev/gpioN"

@Ralim Here's how we might validate the BL602 Pin Functions at Compile Time...

@Ralim Hmmm maybe. But we still need a runtime check to be sure that the GPIOs are not reused
