uart module

baud = 300, 600, 1200, 2400, 4800, 9600, 19200, 38400, 57600, 74880, 115200, 230400, 460800, 921600, 1843200, 2686400. 
心得: Baud Rate可以儘量設高點,太低有時Lua command出錯"
> print("Heap=".. node.heap())
tmr.delay(1000)
print(no>> de.info())

stdin:2: ')' expected (to close '(' at line 1) near 'de'
由上看出,若輸出不夠快則輸入值會影響輸輸入,此應該是Lua的Bug吧!!!!!????(待查證)

註: 各廠USB-Serial不見得支援所有Baud Rate, 例如PL2303 在Ubuntu12.04下不支援 1843200 及2686400,不知是硬體還是軟體限制? 
補充: 同樣Ubuntu環境用FT232RL可設達2686400, 貴一點還是值得的......
補充: 同樣Ubuntu環境用CH341不支援 1843200 及2686400

等待資料接收,最大可設255 Bytes, 下面範例為接收4個bytes

uart.on("data", 4, 
      function(data)
        print("receive from uart:", data)
        if data=="quit" then 
          uart.on("data") 
        end        
    end, 0)
    -- when '\r' is received.
    uart.on("data", "\r", 
      function(data)
        print("receive from uart:", data)
        if data=="quit\r" then 
          uart.on("data") 
        end        
    end, 0)
