pyboard V2已经到了很久了因为项目忙都没时间捣鼓，今天发短信来才注意到。pyboard V2选用的是STM32F4主控芯片。首次插入电脑，我的电脑会增加一个新的设备。
然后打开SecureCRT选择串口和波特率115200，就能出来提示
Traceback (most recent call last):
File "main.py", line 1, in <module>
NameError: name '' is not defined
MicroPython v1.9.4-114-g309fe39d on 2018-06-04; PYBv1.0 with STM32F405RG
Type "help()" for more information.
这是时候可以根据提示输入help();
>>> help()

Quick overview of commands for the board:
pyb.info() -- print some general information
pyb.delay(n) -- wait for n milliseconds
pyb.millis() -- get number of milliseconds since hard reset
pyb.Switch() -- create a switch object
Switch methods: (), callback(f)
pyb.LED(n) -- create an LED object for LED n (n=1,2,3,4)
LED methods: on(), off(), toggle(), intensity(<n>)
pyb.Pin(pin) -- get a pin, eg pyb.Pin('X1')
pyb.Pin(pin, m, [p]) -- get a pin and configure it for IO mode m, pull mode p
Pin methods: init(..), value([v]), high(), low()
pyb.ExtInt(pin, m, p, callback) -- create an external interrupt object
pyb.ADC(pin) -- make an analog object from a pin
ADC methods: read(), read_timed(buf, freq)
pyb.DAC(port) -- make a DAC object
DAC methods: triangle(freq), write(n), write_timed(buf, freq)
pyb.RTC() -- make an RTC object; methods: datetime([val])
pyb.rng() -- get a 30-bit hardware random number
pyb.Servo(n) -- create Servo object for servo n (n=1,2,3,4)
Servo methods: calibration(..), angle([x, [t]]), speed([x, [t]])
pyb.Accel() -- create an Accelerometer object
Accelerometer methods: x(), y(), z(), tilt(), filtered_xyz()
Pins are numbered X1-X12, X17-X22, Y1-Y12, or by their MCU name
Pin IO modes are: pyb.Pin.IN, pyb.Pin.OUT_PP, pyb.Pin.OUT_OD
Pin pull modes are: pyb.Pin.PULL_NONE, pyb.Pin.PULL_UP, pyb.Pin.PULL_DOWN
Additional serial bus objects: pyb.I2C(n), pyb.SPI(n), pyb.UART(n)
Control commands:
CTRL-A -- on a blank line, enter raw REPL mode
CTRL-B -- on a blank line, enter normal REPL mode
CTRL-C -- interrupt a running program
CTRL-D -- on a blank line, do a soft reset of the board
CTRL-E -- on a blank line, enter paste mode
For further help on a specific object, type help(obj)
For a list of available modules, type help('modules')
会有一些命题的提示，这些和LINUX开发板有些类似。

这是一些pyboard V2支持的一些接口。
这时我想点亮LED灯。过程就是这样了
>>> from pyb import LED
>>> led = LED(1)
>>> led.
__class__ intensity off on
toggle
>>> led.toggle()
>>> led.on()
>>> led.off()
>>> led = LED(1)
>>> led.
__class__ intensity off on
toggle
>>> led.toggle()
>>> led.on()
这时，红色LED灯就点亮了，OFF就熄灭。操作很简单的只要有点python知识都可以操作的。
最后想说pyboard V2这块板子很好使用，简单入门。尤其是对于那些没有什么硬件基础，或者想学编程（python）的人来说还是很方便的只要一根USB线连接就可以了，相对于ST出的CUBEMX生成软件，我觉得pyboard V2更好玩。因为时间有限这两个月公司变动比较大，太忙了不然肯定会好好玩一玩pyboard V2这块板子。
