Apache #NuttX RTOS lets us create I/O Expander Drivers that will handle many GPIOs (Input / Output / Interrupt) ... Perfect for #PineDio Stack #BL604!

All 23 GPIOs are fully wired up on #PineDio Stack #BL604! 😲 Let's simplify #NuttX and rename the GPIOs as "/dev/gpio0" to "/dev/gpio22" ... Easier for devs to create NuttX Drivers 👍

What happens when we try to support 23 GPIOs on #PineDio Stack #BL604? Yep the GPIO Names will look really messy on #NuttX RTOS 🤔

"Analysts Predict End is Near for Global Chip Shortage"

#BL602 EVB on #NuttX supports one GPIO Input, one GPIO Output and one GPIO Interrupt ... And names them sequentially: "/dev/gpio0", "/dev/gpio1", "/dev/gpio2" ... Which gets super confusing because "/dev/gpio0" doesn't map to BL602 GPIO Pin 0 🤔
