 -------------------------
-  * Quick reference for the w600
+
+The network module:
+
+.. highlight:: python
+
+::
+
+    import network
+
+    sta_if = network.WLAN(network.STA_IF)
+    sta_if.active(True)
+    sta_if.scan()

+
+
+.. note::  
+
+  MicroPython supports both hardware I2C and software emulation I2C.
+
+  Using **Software I2C** when I2C device ID = -1.

+    print(rtc.now())
+
+.. note::  
+
+  rtc.init((year, month, day[, hour[, minute[, second[, microsecond[, tzinfo]]]]]))
+
+
+SPI
+---------------------
+
+The w60x has 1x hardware SPI, up to 20Mhz.
+
+.. note::  
+
+  Using **software SPI** when the ID is -1.
+
+  Using **hardware SPI** when the ID is 0.
+
+
+.. highlight:: python

+  from machine import Pin, SPI
+
+  spi = SPI(0, baudrate=200000, polarity=1, phase=0, sck=Pin(Pin.PB_16), mosi=Pin(Pin.PB_18), miso=Pin(Pin.PB_17), cs=Pin(Pin.PB_15))
+  spi.read(10)
+  spi.read(10, 0xff)
+  
+  buf = bytearray(50)
+  spi.readinto(buf)
+  spi.readinto(buf, 0xff)
+  
+  spi.write(b'12345')
+  
+  buf2 = bytearray(4)
+  spi.write_readinto(b'1234', buf2)

+Timer
+----------------------
+
+W60X has 6x hardware timers 
+(timer0 is used by WM_SDK, users only have tiemr1-tiemr5 available),
+Use software timer when the ID is -1, use hardware timer when ID is 1-5.
+
+.. highlight:: python
+
+::
+
+  from machine import Timer
+
+  timer1 = Timer(-1)
+  timer1.init(period=5000, mode=Timer.ONE_SHOT, callback=lambda t:print(1))
+  timer3 = Timer(3)
+  timer3.init(period=2000, mode=Timer.PERIODIC, callback=lambda t:print(2))

+UART
+------------------
+
+.. highlight:: python
+
+::
+
+  from machine import UART
+
+  uart = UART(1, 115200)
+  uart.init(115200, bits=8, parity=None, stop=1)
+
+  uart.write('hello world')
+  
+  uart.readline()
+  print(uart.read(5))

+WDT
+---------------
+
+.. highlight:: python
+
+::
+
+    from machine import WDT
+
+    wdt = WDT(0,5000000)
+    wdt.feed()
+
+
+.. note::  
+
+  WM_SDK has added the automatically feed function in lowest priority task.
+  It can run without feeding watch dog in MicroPython.
