Introduction
==============
This project builds out both host tools running on the host side, and an application running on the device side. The device application consists of iwasm, application library, application manager, timers and sensors support. The device runs on Linux OS and interacts with host tools.
It demonstrates an end to end scenario, the wasm applications life cycle management and communication programming models.
"simple" sample introduction
==============
This sample demonstrates following scenarios:
- Use tool "host_tool" to remotely install/uninstall wasm applications from the WAMR runtime over either TCP socket or UART cable
- Inter-app communication programming models
- Communication between WASM applications and the remote app host_tool
- A number of WASM applications built on top of WAMR application framework API sets

The `host_init_func` is called when the application manager starts up. And `host_send_fun` is called by the application manager to send data to the host.
Define a global variable "interface" of the data structure:
```
host_interface interface = {
.init = host_init,
.send = host_send,
.destroy = host_destroy

>**Note:** Currently application manager keeps running and never exit, `host_destroy_fun` has no chance to get executed. So you can leave this API implementation empty.

The main file.
- wasm-apps<br/>
Source files of sample wasm applications.
**Note:** The connection between simple and host_tool is TCP by default. The simple application works as a server and the host_tool works as a client. You can also use UART connection. To achieve this you have to uncomment the below line in CMakeLists.txt and rebuild.
Configure 32 bit or 64 bit build
==============
On 64 bit operating system, there is an option to build 32 bit or 64 bit binaries. In file `CMakeLists.txt`, modify the line:
`set (BUILD_AS_64BIT_SUPPORT "YES")`
where `YES` means 64 bit build while `NO` means 32 bit build.
Install required SDK and libraries
==============
- 32 bit SDL(simple directmedia layer) (Note: only necessary when `BUILD_AS_64BIT_SUPPORT` is set to `NO`)
Use apt-get:
`sudo apt-get install libsdl2-dev:i386`
Or download source from www.libsdl.org:
```
./configure C_FLAGS=-m32 CXX_FLAGS=-m32 LD_FLAGS=-m32
make
sudo make install
```
- 64 bit SDL(simple directmedia layer) (Note: only necessary when `BUILD_AS_64BIT_SUPPORT` is set to `YES`)
Use apt-get:
`sudo apt-get install libsdl2-dev`
Or download source from www.libsdl.org:
```
./configure
make
sudo make install
#add_definitions (-DCONNECTION_UART)`
```
- Install EMSDK
```
https://emscripten.org/docs/tools_reference/emsdk.html
```
To run the UART based test, you have to set up a UART hardware connection between host_tool and the simple application. See the help of host_tool for how to specify UART device parameters.
Build all binaries
Build the sample
==============
Execute the build.sh script then all binaries including wasm application files would be generated in 'out' directory.
`./build.sh`
Or execute the build_no_gui.sh script to build all binaries without gui library support.
`./build_no_gui.sh`

>****Note:**** The connection between simple and host_tool is TCP by default and is what this guide uses. The simple application works as a server and the host_tool works as a client. You can also use UART connection. To achieve this you have to uncomment the below line in CMakeLists.txt and rebuild.

- wasm-apps:
Sample wasm applications that demonstrate all APIs of the WAMR programming model. The source codes are in the wasm-apps directory under the root of this project.
+ connection.wasm<br/>
This application shows the connection programming model. It connects to a TCP server on 127.0.0.1:7777 and periodically sends message to it.
+ event_publisher.wasm<br/>
This application shows the sub/pub programming model. The pub application publishes the event "alert/overheat" by calling api_publish_event() API. The subscriber could be host_tool or other wasm application.
+ event_subscriber.wasm<br/>
This application shows the sub/pub programming model. The sub application subscribes the "alert/overheat" event by calling api_subscribe_event() API so that it is able to receive the event once generated and published by the pub application. To make the process clear to interpret, the sub application dumps the event when receiving it.
+ gui.wasm<br/>
This application shows the built-in 2D graphical user interface API with which various widgets could be created.
+ request_handler.wasm<br/>
This application shows the request/response programming model. The request handler application registers 2 resources(/url1 and /url2) by calling api_register_resource_handler() API. The request sender could be host_tool or other wasm application.
+ request_sender.wasm<br/>
This application shows the request/response programming model. The sender application sends 2 requests, one is "/app/request_handler/url1" and the other is "url1". The former is an accurate request which explicitly specifies the name of request handler application in the middle of the URL and the later is a general request.
+ sensor.wasm<br/>
This application shows the sensor programming model. It opens a test sensor and configures the sensor event generating interval to 1 second. To make the process clear to interpret, the application dumps the sensor event when receiving it.
+ timer.wasm<br/>
This application shows the timer programming model. It creates a periodic timer that prints the current expiry number in every second.
