+
+A serial port debugger tool, with lua script.
+
+> this tools is only Chinese now, you can help me to translate, thanks!
+
+## Download
+
+Release page stable version: [GitHub](https://github.com/chenxuuu/llcom/releases/latest)
+
+Appveyor snapshot version: [Appveyor Artifacts](https://ci.appveyor.com/project/chenxuuu/llcom/build/artifacts)
+
+## Functions
+
+- Basic functions of serial port debugger tools.
+- The log is clear with two colors, display both HEX values and strings at same time.
+- Auto save serial and lua script logs, with time stamp.
+- Auto reconnect serial port after disconnected.
+- Data you want to send can be processed with your own Lua scripts.
+- Quick send bar on the right.
+- Lua scripts can be run independently with timer and co-process task features.([Based on LUAT TASK](http://wiki.openluat.com/doc/luatFramework/))

+
+## features' exemplary
+
+### Use Lua script process data you want to send
+
+1. end with "\r\n"
+
+```lua
+return uartData.."\r\n"
+```
+
+2. send HEX values
+
+```lua
+return uartData:fromHex()
+```
+
+this script can change `30313233` to `0123`.
+
+3. another script example
+
+```lua
+json = require("JSON")
+t = uartData:split(",")
+return JSON:encode({
+    key1 = t[1],
+    key2 = t[2],
+    key3 = t[3],
+})
+```
+
+this script can change `a,b,c` to `{"key1":"a","key2":"b","key3":"c"}`.
+
+**these scripts also work with Quick send bar**
+
+### independent script auto process uart sand and receive
+
+you can run your own Lua script on the right, such as llcom's example:
+
+```lua
+--register serial port receiver function
+uartReceive = function (data)
+    log.info("uartReceive",data)
+    sys.publish("UART",data)--publish message
+end
+
+--create a task, wait for message
+sys.taskInit(function()
+    while true do
+        local _,udata = sys.waitUntil("UART")--wait for message
+        log.info("task waitUntil",udata)
+        local sendResult = apiSendUartData("ok!")--send uart data
+        log.info("uart send",sendResult)
+    end
+end)
+
+--reate a task, sleep 1000ms and loop
+sys.taskInit(function()
+    while true do
+        sys.wait(1000)--wait 1000ms
+        log.info("task wait",os.time())
+    end
+end)
+
+--1000ms loop timer
+sys.timerLoopStart(log.info,1000,"timer test")
+```
+
+you alse can use `xlua` to use C# codes
+
+```lua
+request = CS.System.Net.WebRequest.Create("http://example.com")
+request.ContentType = "text/html;charset=UTF-8";
+request.Timeout = 5000;
+request.UserAgent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/71.0.3578.98 Safari/537.36 Vivaldi/2.2.1388.37";
+
+response = request:GetResponse():GetResponseStream()
+
+myStreamReader = CS.System.IO.StreamReader(response, CS.System.Text.Encoding.UTF8);
+
+print(myStreamReader:ReadToEnd())--get body
+
+myStreamReader:Close()
+response:Close()
+```
