Type "help()" for more information.
>>> help()
Welcome to MicroPython!
For online help please visit https://micropython.org/help/.
For access to the hardware use the 'machine' module. RP2 specific commands
are in the 'rp2' module.
Quick overview of some objects:
machine.Pin(pin) -- get a pin, eg machine.Pin(0)
machine.Pin(pin, m, [p]) -- get a pin and configure it for IO mode m, pull mode p
methods: init(..), value([v]), high(), low(), irq(handler)
machine.ADC(pin) -- make an analog object from a pin
methods: read_u16()
machine.PWM(pin) -- make a PWM object from a pin
methods: deinit(), freq([f]), duty_u16([d]), duty_ns([d])
machine.I2C(id) -- create an I2C object (id=0,1)
methods: readfrom(addr, buf, stop=True), writeto(addr, buf, stop=True)
readfrom_mem(addr, memaddr, arg), writeto_mem(addr, memaddr, arg)
machine.SPI(id, baudrate=1000000) -- create an SPI object (id=0,1)
methods: read(nbytes, write=0x00), write(buf), write_readinto(wr_buf, rd_buf)
machine.Timer(freq, callback) -- create a software timer object
eg: machine.Timer(freq=1, callback=lambda t:print(t))
Pins are numbered 0-29, and 26-29 have ADC capabilities
Pin IO modes are: Pin.IN, Pin.OUT, Pin.ALT
Pin pull modes are: Pin.PULL_UP, Pin.PULL_DOWN
Useful control commands:
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')

minicom 无法退出 bug ❌
按 Ctrl + A 可以切换到 > 模式；但是再依次按 Z 键，X 键 也无法退出 ❓ 不好使 ❌
按 Ctrl + A 连续按两次也不好使 ❌
按 Ctrl + B 可以切换到 >>> MicroPython 的 REPL 模式；
>>> help() 可以正常使用 ✅
