What if we...

1. Compile the uLisp Interpreter to WebAssembly...

2. Use the WebAssembly version of uLisp to simulate BL602 in a Web Browser...

   (Including GPIO, I2C, SPI, Display Controller, Touch Controller, LoRaWAN... Similar to this)

3. Integrate the BL602 Emulator with Blockly...

4. To allow embedded developers to preview their BL602 Blockly Apps in the Web Browser?

Let's try this out here with the wasm branch of ulisp-bl602

• Watch the uLisp WebAssembly demo on YouTube

• Try uLisp WebAssembly here

The BL602 Simulator also works with Blockly to preview for dragged-and-dropped uLisp Blockly Apps...

• Watch the BL602 Simulator + uLisp WebAssembly + Blockly demo on YouTube

• Try BL602 Simulator + uLisp WebAssembly + Blockly here

• uLisp Blockly source code

• src/ulisp.c: uLisp Interpreter for BL602 and WebAssembly, ported from uLisp for ESP32

• wasm/wasm.c: WebAssembly integration for uLisp (JSON Stream for Simulation Events)

• docs/ulisp.html: HTML file with JavaScript that invokes uLisp WebAssembly for REPL

• wasm.mk: Build uLisp WebAssembly with Emscripten

To build uLisp for WebAssembly with Emscripten...

make -f wasm.mk

The compiled files ulisp.js and ulisp.wasm will be copied to docs.

To test, run a local web server and browse to docs/ulisp.html.

(WebAssembly requires a local web server, it won't run from the local filesystem)

A version of the Lisp programming language for BL602 RISC-V boards.
