#Embedded #Programming has come a long way since the Arduino days ... Let's learn it the new way with #RustLang, #WebAssembly and #PineTime Smart Watch @PINE64 !

https://lupyuen.github.io/pinetime-rust-mynewt/articles/handdrawn

Funny that #WebAssembly and #Embedded #RustLang work so well together ... I'll explain with #PineTime Watch Faces

No more #RustLang "unsafe" code for #PineTime Hand-Drawn Watch Face yay!

#Emscripten and #PineTime #WebAssembly Simulator builds OK on plain old Windows CMD ... Yep I'm surprised

@PINE64 #Embedded Memory Concerns: The 10 digit bitmaps take up 160 KB of ROM ... To fit this into #PineTime's 512 KB Flash ROM, we need to throw out the large font (keeping the small font) ... Welcome to The Real World 🙂
