inter n! ati f429 rep code dom art 推薦
保存“main.py”文件,完成復位即可。
工具 :
- putty
- F429Discovery 開發板
- Notepad++
註意:不知道為什麽 其他的終端工具有問題,推薦 putty 基本沒有發現問題
putty 實時調試
- 使用putty 打開USB 虛擬串口,我們打開可以使用
help()
方法尋求幫助
輸入help()
如下所示
help() Welcome to MicroPython! For online help please visit http://micropython.org/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‘)
上面就是所有的Micro Python 幫助文檔。
輸入下面的指令打開一個Led。
>>> import pyb
>>> led = pyb.LED(1)
>>> led.on()
>>> led.off()
MicroPython 脫機運行
脫機運行指離開電腦獨立運行,在插入USB的時候,電腦多了一個磁盤(不是Stlink V2.1),我們打開這個磁盤,裏面有一個“main.py”文件。
打開這個文件,可以在裏面輸入如下代碼
Python import pyb while true: pyb.LED(1).on() pyb.delay(500) pyb.LED(1).off() pyb.delay(500)
保存“main.py”文件,完成復位即可。
