ST7789 Display is wired "backwards" on #PineDio Stack #BL604 ... We fix this by swapping the MISO / MOSI Pins in the #NuttX SPI Driver
https://github.com/lupyuen/pinedio-stack-nuttx#swap-miso--mosi
Wordle is NP-hard
We create an SPI Device Table in #NuttX that defines each device wired to the SPI Bus ... NuttX SPI Driver will use this table to control the SPI Bus
https://github.com/lupyuen/pinedio-stack-nuttx#shared-spi-bus
SPI Bus on #PineDio Stack #BL604 is wired to 3 devices: 1️⃣ ST7789 Display 2️⃣ LoRa SX1262 3️⃣ SPI Flash ... Each with its own Chip Select Pin ... Let's tweak #NuttX RTOS to support this

@lupyuen Yeah, i really like Sailfish OS. I use it like @vattuvarg for years. First on a community port and later with the release of the "Jolla C" with official devices. ATM with a Xperia XA2 Ultra. maybe i will switch to the smaller 10III once the ROM is ready. Why not a community port (PinePhone)? Because i need some Android apps y.y
But #SailfishOS is the best alternative mobile OS. Others like PureOS, Mobian or PostmarketOS are not mature enough for my needs.

@lupyuen - I have been running #sailfishOS on my main phones since 2014. ...and a Xperia 10iii is waiting for its turn.

@lupyuen I come from the time when MeeGo was Moblin. Ran it on my eee-pc clamshell.
