# com-chilipeppr-workspace-esp32-lua
A ChiliPeppr Workspace that lets you interact with an ESP32 Lua device (NodeMCU for ESP32). The device is an ESP32 wifi module with an attached USB serial port bridge so you can easily use it and program it from your computer via the serial port. Thus, the esp32 works brilliantly with ChiliPeppr. Secondly, the esp32 has the Lua language preloaded onto it so you can easily program the device.This workspace gives you convenience methods for programming the esp32 device. You can buy the esp32 on ebay.com or aliexpress.com.

## ChiliPeppr Workspace / ESP32 for Lua (NodeMCU)

All ChiliPeppr workspaces/widgets/elements are defined using cpdefine() which is a method
that mimics require.js. Each defined object must have a unique ID so it does
not conflict with other ChiliPeppr objects.

## Example Code for chilipeppr.load() Statement

You can use the code below as a starting point for instantiating this workspace 
from ChiliPeppr's Edit Boot Script dialog box. The key is that you need to load 
your workspace inlined into the standard #pnlWorkspace div so the DOM can parse your HTML, CSS, and 
Javascript. Then you use cprequire() to find your workspace's Javascript and get 
back the instance of it to init() it.

```javascript
// This code should be pasted into the ChiliPeppr Edit Boot Javascript dialog box
// located in the upper right corner of any chilipeppr.com page.
// The ChiliPeppr environment has a standard div called #pnlWorkspace that
// this workspace should be loaded into.
chilipeppr.load(
  "#pnlWorkspace",
  "http://raw.githubusercontent.com/chilipeppr/workspace-esp32-lua/master/auto-generated-workspace.html",
  function() {
    // Callback after workspace loaded into #pnlWorkspace
    // Now use require.js to get reference to instantiated workspace
    cprequire(
      ["inline:com-chilipeppr-workspace-esp32-lua"], // the id you gave your workspace
      function(myWorkspaceEsp32Lua) {
        // Callback that is passed reference to the newly loaded workspace
        console.log("Workspace / ESP32 for Lua (NodeMCU) just got loaded.", myWorkspaceEsp32Lua);
        myWorkspaceEsp32Lua.init();
      }
    );
  }
);

```

## About ChiliPeppr

[ChiliPeppr](http://chilipeppr.com) is a hardware fiddle, meaning it is a 
website that lets you easily
create a workspace to fiddle with your hardware from software. ChiliPeppr provides
a [Serial Port JSON Server](https://github.com/johnlauer/serial-port-json-server) 
that you run locally on your computer, or remotely on another computer, to connect to 
the serial port of your hardware like an Arduino or other microcontroller.

You then create a workspace at ChiliPeppr.com that connects to your hardware 
by starting from scratch or forking somebody else's
workspace that is close to what you are after. Then you write widgets in
Javascript that interact with your hardware by forking the base template 
widget or forking another widget that
is similar to what you are trying to build.

ChiliPeppr is massively capable such that the workspaces for 
[TinyG](http://chilipeppr.com/tinyg) and [Grbl](http://chilipeppr.com/grbl) CNC 
controllers have become full-fledged CNC machine management software used by
tens of thousands.

ChiliPeppr has inspired many people in the hardware/software world to use the
browser and Javascript as the foundation for interacting with hardware. The
Arduino team in Italy caught wind of ChiliPeppr and now
ChiliPeppr's Serial Port JSON Server is the basis for the 
[Arduino's new web IDE](https://create.arduino.cc/). If the Arduino team is excited about building on top
of ChiliPeppr, what
will you build on top of it?
