luatos's Introduction

LuatOS是运行在嵌入式硬件的实时操作系统,只需要少量内存的flash空间就能运行,用户编写lua代码就可完成各种功能

Lua base RTOS, build for many embedded systems

基于Lua 5.3.5
低内存需求, 最低32kb, 96kb flash空间
硬件抽象层兼容M3/arm/risc-v等
可测试,可模拟(qemu)
在线升级
可裁剪,可扩展

代码示例节选

详细代码请查阅 script/app/playit/main.lua

local sys = require("sys")

sys.subscribe("WLAN_READY", function ()
    print("!!! wlan ready event !!!")
    -- 马上进行时间同步
    socket.ntpSync()
end)

disp.init("ssd1306")
display_str("Booting ...")

-- 配网回调
sys.subscribe("WLAN_PW_RE", function(ssid, password)
    if ssid then
        log.info(TAG, "airkiss GOT", ssid, password)
        local conf = {ssid=ssid,password=password}
        json.encodeFile(conf, "/wlan.json")
    else
        log.info(TAG, "airkiss fail")
    end
end)

-- 业务流程, 联网后定时发送温度数据到服务器
sys.taskInit(function()
    while 1 do
        if wlan.ready() == 1 then
            sys.wait(1000)
            local temp = (sensor.ds18b20(28) or "")
            display_str("Temp: " .. temp  .. " rssi:" .. tostring(wlan.rssi()))
            local t = {"GET /api/w60x/report/ds18b20?mac=", wlan.get_mac(), "&temp=", temp, " HTTP/1.0\r\n",
                    "Host: site0.cn\r\n",
                    "User-Agent: LuatOS/0.1.0\r\n",
                        "\r\n"}
            socket.tsend("site0.cn", 80, table.concat(t))
            log.info("network", "tsend complete, sleep 5s")
            sys.wait(5000)
        else
            log.warn("main", "wlan is not ready yet")
            sys.waitUntil("WLAN_READY", 30000)
        end
    end

-- 主循环, 必须加
sys.run()
