Let's build a simple Simulator for #BL602 ... With #uLisp, #WebAssembly and #Blockly

https://github.com/lupyuen/ulisp-bl602/tree/wasm

We compile #uLisp with Emscripten ... And turn it into a #WebAssembly App

https://github.com/lupyuen/ulisp-bl602/blob/wasm/wasm.mk

We stub out the GPIO Functions in #uLisp #WebAssembly ... They shall be simulated with JavaScript in our #BL602 Simulator

https://github.com/lupyuen/ulisp-bl602/blob/wasm/src/ulisp.c#L48-L57

#uLisp Interpreter runs in #WebAssembly ... Thanks to #Emscripten yay!

#uLisp in #WebAssembly ... Try it here: https://lupyuen.github.io/ulisp-bl602/ulisp.html

#BL602 Simulator is super helpful ... For catching, fixing and testing tricky firmware bugs like this

Pondering #BL602 Simulator ... With uLisp and WebAssembly 🤔

https://github.com/lupyuen/ulisp-bl602/tree/wasm

#uLisp #WebAssembly shall send #BL602 Simulator a JSON Stream of Simulation Events ... Looks like a MIDI Stream 🤔

https://github.com/lupyuen/ulisp-bl602/tree/wasm

Here's the JSON Stream of #BL602 Simulation Events in #WebAssembly ... When #uLisp sets the GPIO Output, a Simulation Event gets added to the JSON Stream

https://github.com/lupyuen/ulisp-bl602/blob/wasm/wasm/wasm.c#L7-L32

Here's how #uLisp #WebAssembly adds a Simulation Event to the JSON Stream ... For #BL602 GPIO Output

https://github.com/lupyuen/ulisp-bl602/blob/wasm/wasm/wasm.c#L54-L71

#uLisp #WebAssembly generates this JSON Stream of #BL602 Simulation Events ... Now we interpret the Simulation Events and blink the Simulated #BL602 LED

How we return a String from #WebAssembly to JavaScript ... In our #BL602 Simulator

https://github.com/lupyuen/ulisp-bl602/blob/wasm/docs/ulisp.html#L1339-L1379

Our #BL602 Simulator needs a board pic ... Let's use this wriggly sketch for now 😬

How we render our #BL602 Simulator pic to the HTML Canvas 🎨

How we handle the #BL602 Simulation Events generated by #uLisp #WebAssembly

How we render the Simulated LED in our #BL602 #WebAssembly Simulator

#BL602 Simulator ... #uLisp #WebAssembly flips our Simulated LED yay! 🎉

https://lupyuen.github.io/ulisp-bl602/ulisp.html

To blink the Simulated #BL602 LED ... We need to Simulate the Delays too ... Here's how

https://github.com/lupyuen/ulisp-bl602/blob/wasm/docs/ulisp.html#L1467-L1472

Here's our #BL602 Simulator simulating a Delay from #uLisp WebAssembly

https://lupyuen.github.io/ulisp-bl602/ulisp.html

Simulating #uLisp Loops ... We can't allow uLisp to emit an Infinite List of #BL602 Simulation Events ... So we stop uLisp Loops before the Event List gets too long

https://github.com/lupyuen/ulisp-bl602/blob/wasm/wasm/wasm.c#L34-L46

#BL602 Simulator blinking a Simulated LED ... Thanks to #uLisp WebAssembly

https://lupyuen.github.io/ulisp-bl602/ulisp.html

Let's add our #BL602 Simulator to #Blockly for uLisp ... So that we can preview Blockly Apps in the Web Browser!
