Can we Simulate #BL602 #RustLang Firmware in a Web Browser with #WebAssembly? ... So we can make a PineDio Stack Simulator? 🤔

https://github.com/lupyuen/bl602-simulator

To compile #BL602 #RustLang Firmware into #WebAssembly ... 1️⃣ Change "no_std" to "libc" 2️⃣ Exclude the Panic Handler

https://github.com/lupyuen/bl602-simulator/blob/main/sdk_app_rust_gpio/rust/src/lib.rs

We build the #BL602 #RustLang Firmware for target "emscripten" ... Because we'll be linking with Emscripten libraries

https://github.com/lupyuen/bl602-simulator/blob/main/README.md#build-bl602-rust-firmware-for-webassembly

#BL602 #RustLang Firmware runs OK with #WebAssembly ... When we reused the WebAssembly Stubs from uLisp yay! 🎉

What drives the #BL602 #RustLang Simulator in #WebAssembly? A JSON Stream of Simulation Events!

https://lupyuen.github.io/articles/wasm#simulate-bl602-hardware

Composing JSON in C looks messy ... Let's convert to #RustLang

https://github.com/lupyuen/bl602-simulator/blob/main/wasm/wasm.c

Here's how we compose a JSON Stream of #BL602 Simulation Events in #RustLang

https://gist.github.com/lupyuen/cec1a423062556263a7ba02971862001

Here are the #RustLang Stubs that intercept calls to #BL602 IoT SDK ... And emit the JSON Stream of Events

https://github.com/lupyuen/bl602-simulator/blob/main/bl602-simulator/src/lib.rs#L85-L135

Maybe with #BL602 Simulator ... Learning #Embedded Coding becomes a little easier? 🤔

https://github.com/lupyuen/bl602-simulator

If #BL602 IoT SDK wasn't called correctly ... Our BL602 Simulator could show a helpful message 🤔

https://github.com/lupyuen/bl602-simulator/blob/main/bl602-simulator/src/lib.rs#L85-L109

How our #BL602 Simulator in #WebAssembly checks the GPIO Pin Config ... When setting the GPIO Pin Output

https://github.com/lupyuen/bl602-simulator/blob/main/bl602-simulator/src/lib.rs#L105-L136

If we set a GPIO Pin Output without configuring the GPIO for Output ... Our #BL602 #WebAssembly Simulator halts with a helpful message

Added Rhai #RustLang Scripting Engine to #BL602 WebAssembly Simulator ... So that we can do interesting things 🤔

https://github.com/lupyuen/bl602-simulator/blob/main/bl602-script/src/lib.rs

Here's how we expose our #RustLang Functions to Rhai Script Engine

https://github.com/lupyuen/bl602-simulator/blob/main/bl602-script/src/lib.rs#L25-L88

How we handle #BL602 Simulation Events in JavaScript ... And blink the Simulated BL602 LED
