Nodemcu Lora模塊庫

lora sx1276/sx1278無線電通信模塊的nodemcu lua庫

該庫是根據https://github.com/jaapbraam/lorawangateway的圖書館的

改進：

修復了在消息緩衝區上使用錯誤操作的錯誤，這導致發送垃圾而不是實際消息
增強電源管理以支持20DBM模式
- 實施靈感來自https://github.com/sandeepmistry/arduino-lora/blob/master/src/lora.cpp

我不是實施此類圖書館的專家，我不了解大多數這些註冊表操作，但是我以某種方式對我有用？

大多數學分都歸功於上述圖書館的作者，他們必須經常研究SX1276手冊？

用法

API

 local radioLib = require ( ' sx1276.lua ' )

local nssPin = 0
local dio0Pin = 1
local dio1Pin = 2

local frequency = 433.000 * 1000000 -- Frequency in Hz
local spreadingFactor = " SF7 " -- "SF7" - "SF12" 
local bandWidth = " BW125 " -- I think only this one is supported
local errorCorrection = " 4/5 " -- I believe these are supported: "4/5", "4/6", "4/7", "4/8"

local radioInterface = radioLib (
  nssPin ,
  dio0Pin ,
  dio1Pin ,
  frequency ,
  spreadingFactor ,
  bandWidth ,
  errorCorrection
)

-- Receiving

local function handleMessage ( pkt )
  print ( " RX! " )
  print ( " Data: " , pkt . data )
  print ( " RSSI: " , pkt . rssi )
  for k , v in pairs ( pkt ) do
      print ( k , v )
  end
end

radioInterface . rxpk = handleMessage

-- Transmitting

local pkt = {
    freq = frequency ,
    codr = errorCorrection ,
    datr = spreadingFactor .. bandWidth ,
    data = " Here goes your message " ,
    powe = 17 -- values 0..20
}

radio . txpk ( pkt )
