New c-style OOP scripting framework and IDE

Postby ZHDX227 » Thu Nov 22, 2018 6:20 am

Hi everyone,

I am making a script solution to implement my ideas into chip easier.

mcs_02.png (194.32 KiB) Viewed 2147 times
Key features:

1 - Good IDE
Usb connect and play, Click and run script in 1 second , Save as startup script without PC connected.
CPU/Memory/Network status monitoring, Log output , Fixed position Text/Image output.

2 - Powerful scripting language
C-Style , weak/strong type , closure , class/function/delegate , class inside function , function inside class
virtual/override OOP , property getter/setter, JSON , Binary serialization
try/catch/finally , exception stacktrace and line number ,
Eval script string, Asynchronize programming, Multi-Task programming , foreach keyword for list/dict
Work with custom c++ code, pre-compile into C++ code for obfuscation and better performance .
Object destruction callback , Object attached dictionary , .... etc ....

3 - Memory (WROOM):
Spend 55K memory when startup, and 260K free for play ideas.
Spend 38K for WIFI+LWIP , 220K free for client/server.
Spend 30-40K for Http library , 180K free for fast Http client/server scripting

4 - IO:
GPIO/PWM/SPI , tested 320x240 TFT as 16 FPS , need more time for others

5 - Network Performance
Big Buffer: WROOM 900KB/s , WROVER 1.5MB/s
(Depend on the buffer setting in menuconfig)
Small Buffer: about 18 socket connection + 330 http keep-alive requests per second .
Tested 12 connections in WROOM

------

Now It works and stable, just still need 3-4 months to finish more libraries.

Will be available at 2019

The script language , code syntax samples,

24 line class to implement a protocol
which help me to control the gpio 26 LED from remote side

Code: Select all

class MCSCloudClient
{
    var url,key,pwd,dev,sid,headers;
    function MCSCloudClient(argurl, argkey, argpwd, argdev, argheaders) {
		url = argurl;key = argkey;pwd = argpwd;dev = argdev;headers=argheaders;
	}
    function SendRequestTask(cmd, args) {
		var ht=Http.Post(url,headers,Object.Stringify({ cmd: cmd, args: args, sid: sid, key: key, pwd: pwd, dev: dev }));
		var obj=ht.ReadJsonObject();
		if(obj.error)throw("error "+obj.error+" : "+obj.result);
		return obj.result;
	}
	function Send() {
		return SendRequestTask("Send", $arguments);
	}
	function Read() {
		return SendRequestTask("Read", []);
	}
	function ConnectPeer(group) {
		var peer = new MCSCloudClient(url, key, pwd, dev,headers);
		peer.sid = peer.SendRequestTask("Peer", [group]);
		return peer;
	}
}


var mcc = new MCSCloudClient("http://192.168.1.77:88/test/CloudHandler.ashx", "myapikey", "myapipwd", "mydevice");

var peer = mcc.ConnectPeer("group1");

MCS.Log("DONE"+peer.sid);

Gpio out26=Gpio.Out(26);

while(true)
{
    var arr = peer.Read();
    foreach(var obj in arr)
    {
        if(obj[0]=="led-1")
        {
            out26.SetLevel(1);
        }
        if(obj[0]=="led-0")
        {
            out26.SetLevel(0);
        }
    }
}
100 lines code to show MJpeg stream into TFT monitor

Demo of the IDE Button idea

--

Recent update : optimized memory usage.
Now it support 16 active TCP concurrent connections and read or write small pieces 1000+ times per second.

--

The IDE helps to monitor the status of the chip

It's very helpful for the prototype of a product , or just test the pin-connection ,

Or a good peer debugger when connect another chip with UART/SPI/I2C/UDP/TCP etc .

Mate, your job looks absolutely amazing. :shock: Where can I get this tool from?
