Let's build an #IoT App with #ZigLang and #LoRaWAN ... To show that we can maintain and extend Complex IoT Apps with Zig!

https://github.com/lupyuen/zig-bl602-nuttx#convert-lorawan-app-to-zig

We take this #LoRaWAN App in C and convert to #ZigLang ... 700 Lines of C Code, no sweat!

https://github.com/lupyuen/zig-bl602-nuttx#convert-lorawan-app-to-zig

Here's how we import #LoRaWAN Library from C into #ZigLang ... Yep Zig understands C Header Files! 👍

https://github.com/lupyuen/zig-bl602-nuttx#convert-lorawan-app-to-zig

This is how we call the #LoRaWAN Library from #ZigLang

https://github.com/lupyuen/zig-bl602-nuttx#convert-lorawan-app-to-zig

#ZigLang Compiler will helpfully Auto-Translate our code from C to Zig ... Rewriting C to Zig gets so much easier 👍

Our #LoRaWAN App ... Original C code vs Auto-Translated #ZigLang code

https://github.com/lupyuen/zig-bl602-nuttx#auto-translate-lorawan-app-to-zig

Auto-Translating C to #ZigLang is not perfect (like for C Bit Fields) ... But we can fix it ourselves

https://github.com/lupyuen/zig-bl602-nuttx#opaque-type-error

#ZigLang Compiler can't Auto-Translate some tricky C Macros into Zig ... Here's a workaround

https://github.com/lupyuen/zig-bl602-nuttx#macro-error

#ZigLang Compiler won't init this C Struct ... So we init the struct ourselves

https://github.com/lupyuen/zig-bl602-nuttx#struct-initialisation-error

After fixing the code, our #LoRaWAN #ZigLang App runs perfectly on Apache #NuttX RTOS! 🎉 (670 lines of Zig code!)

Building an #IoT App with #ZigLang and #LoRaWAN ... All shall be explained in this article

https://lupyuen.github.io/articles/iot?1

Our #LoRaWAN Stack for #ZigLang is in C ... And that's perfectly OK!

https://lupyuen.github.io/articles/iot?2#lorawan-network-stack

Importing the #LoRaWAN Library from C into #ZigLang ... Piece of cake!
