#RustLang opens GPIO Ports on Apache #NuttX OS ... The POSIX Way 👍

https://github.com/lupyuen/incubator-nuttx-apps/blob/rust/examples/rust_test/rust/src/lib.rs#L10-L27

Once we implement the #RustLang Embedded HAL on #NuttX OS ... We can run all kinds of Rust Drivers on NuttX! 👍

#RustLang runs OK on #NuttX OS ... We're ready to create Rust Embedded Apps on NuttX! 🎉

https://github.com/lupyuen/incubator-nuttx-apps/blob/rust/examples/rust_test/rust/src/lib.rs

#RustLang builds OK with #NuttX OS! 🎉 Let's run the NuttX Firmware

https://gist.github.com/lupyuen/9bfd71f7029bb66e327f89c8a58f450d

Our #NuttX Build Script compiles the #RustLang code into a Static Library ... And links the Static Library into the NuttX Firmware

https://github.com/lupyuen/incubator-nuttx-apps/blob/rust/examples/rust_test/run.sh#L85-L103

Let's run this #RustLang program on Apache #NuttX OS

https://github.com/lupyuen/incubator-nuttx-apps/blob/rust/examples/rust_test/rust/src/lib.rs

Porting TinyCBOR to #NuttX is easy ... Thanks to POSIX Support on NuttX!

Let's encode Sensor Data with CBOR on Apache #NuttX OS

https://github.com/lupyuen2/tinycbor-nuttx

Apache #NuttX OS talks to The Things Network over #LoRaWAN! 🎉

"Future Leader" 🤔

We're ready to build a complete #IoT Sensor Device with Apache #NuttX OS ... Just add #LoRaWAN, CBOR and The Things Network!

https://lupyuen.github.io/articles/lorawan3?32#whats-next

We might need SPI with DMA ... For #LoRaWAN on #NuttX OS
