GcOpsJs

node.js interface for G.C. H/W gamepad emulator.

Overview

G.C. H/W gamepad emulator can be controlled from not only GUI programming environment (e.g. Makecode, Node-RED), but also program. This repository contains node.js sample codes.

There are two methods,

1. Network access
2. Direct access

---

1. Network access

This method is best for easy-to-use system.

Requirements

H/W

• PC(win/mac/linux)
• G.C. H/W gamepad emulator
• Raspberry Pi (* as G.C. host)

S/W

• node.js (>8.0)
• node.js libraries
  • node-serialport
  • node-red-contrib-game_controllerizer
  • websocket (* any other websocket libraries also avairable.)

node-red-contrib-game_controllerizer is the library for Node-RED basically. But, programmer can call inner functions of the library directly.

Step-1. H/W setup

Setup G.C. H/W emulator and RasPi kit. See node-red-contrib-game_controllerizer library page. After the Node-RED is running on RasPi, import chearsheet as predefined Node-RED flow.

Step-2. Run an example code

# clone this repository
% git clone https://github.com/GameControllerizer/GcOpsJs
% cd GcOpsJs
# setup libraries
% npm i serialport
% npm i node-red-contrib-game_controllerizer
% npm i websocket
# run an example code
% node -v
v8.10.0
# !!! Do not forget to configure websocket port & host defined in the example code !!!
% node example_network.js

When the program is runnning, the marker of ws:/gamepad node in MISC tab must be green as followed.

2. Direct access

This method is best for low latency system.

Requirements

H/W

• PC(win/mac/linux)
• G.C. H/W gamepad emulator
• USB serial interface (e.g. FT23x)
• UBS cables

S/W

same as 'Network access'

Step-1. H/W setup

Step-2. Run an example code

# clone this repository
% git clone https://github.com/GameControllerizer/GcOpsJs
% cd GcOpsJs
# setup libraries
% npm i serialport
% npm i node-red-contrib-game_controllerizer
# run an example code
% node -v
v8.10.0
# !!! Do not forget to configure serialport name defined in the example code !!!
% node example_direct.js

Note

All the programmer have to do is call GcOps.toBytes() function to convert JSON based command list into bytes. Check DSL4GC for command format.
