把CI搭起来, 在编译文档写好之后
基于wifi的LBS定位
配合飞思创的开发板, 名称暂定playit

先把原始代码贴上
local sys = require "sys"
log.info("main", "uart demo")
local uartid = 1
local recvBuff = {{}, {}}
--初始化
local result = uart.setup(
uartid,--串口id
115200,--波特率
8,--数据位
1--停止位
)
local function read(uid)
local s = table.concat(recvBuff[uid])
recvBuff[uid] = {}
uart.write(uartid,s)
end
sys.timerLoopStart(function()
log.info("RAM:", _G.collectgarbage("count"))-- 打印占用的RAM
end, 1000)
local function taskRead()
uart.on(
1,
'receive',
function(uid, length)
table.insert(recvBuff[uid], uart.read(uid, length or 1024))
sys.timerStart(sys.publish, 50, 'UART_RECV_WAIT_', uid)
end
)
end
sys.subscribe('UART_RECV_WAIT_', read)
sys.taskInit(taskRead)
sys.run()RT

使用playit脚本, 一段时间后(期间操作过串口, 发free/list_thread/list_memheap), 报以下错误
((header_ptr->magic & RT_MEMHEAP_MASK) == RT_MEMHEAP_MAGIC) assertion failed at function:rt_memheap_free, line number:515

测试W600 onchip flash的读写寿命
做gpio rtt实现的时候一起做了吧

memheap的头部有24字节, 应替换为更经济的内存管理算法
好东西。不知道这个操作系统能不能用在合宙的4g模块，c_sdk开发上，
我在官网上看到合宙是有c_sdk环境开发的，对这个有点兴趣，不过这个开发包好像很久没有维护了
可以用rebase的方式合并分支，这样commit里面就不会有多余的分支合并信息

让socket库支持TLS连接, 起码要访问以下网站正常
扩展测试:
提醒:
似乎W60x的AES硬件加速有问题, 停用该加速后, 默认mbedtls配置能访问 https://rt-thread.org
这个任务的主要工作是将 mqtt.lua 中的部分逻辑, 使用C语言实现到luat_lib_mqttcore.c
欢迎领取上述小任务, 领取后请在1周内完成. 以上任务没有依存关系, 均可独立提交成果.
推荐使用pull request方式提交.
提交pr后, 请签署 CLA , 仅第一次提交时需要签署.
当前版本的netc仅支持了TCP连接

这样又减少了自行存储wifi的操作
现在已经有w60x和qemu两个板子作为实现
