uPydevice

Python library to interface with Micropython devices through WebREPL protocol or through Serial connection.

Requirements

• upydev
• picocom
• pyserial

upydev and pyserial will be automatically installed with pip

to install picocom do: brew install picocom

Install

pip install upydevice

Example usage:

WIRELESS DEVICE (WebREPL Protocol)

    >>> from upydevice import W_UPYDEVICE
# Setup and configurate a device :

    >>> esp32 = W_UPYDEVICE('192.168.1.56', 'mypass') # (target_ip, password)

# Send command:
    >>> esp32.cmd('led.on()')

    >>> esp32.cmd("uos.listdir('/')")
      ['boot.py', 'webrepl_cfg.py', 'main.py'] # this output is stored in [upydevice].output

    >>> esp32.output
      ['boot.py', 'webrepl_cfg.py', 'main.py']

    >>> esp32.cmd('foo()')

    >>> esp32.cmd('x = [1,2,3];my_var = len(x);print(my_var)')
    3

# Soft Reset:
    >>> esp32.reset()
    Rebooting device...

    ### closed ###

    Done!

SERIAL DEVICE (Picocom, Pyserial)

    >>> from upydevice import S_UPYDEVICE

# Setup and configurate a device :
    >>> esp32 = S_UPYDEVICE('/dev/tty.SLAB_USBtoUART', 1000, 115200) # defaults (serial_port, timeout=1000, baudrate=9600)

# Send command:
    >>> esp32.cmd('led.on()')

    >>> esp32.cmd("uos.listdir('/')")
    ['boot.py', 'webrepl_cfg.py', 'main.py'] # this output is stored in [upydevice].output

    >>> esp32.output
    ['boot.py', 'webrepl_cfg.py', 'main.py']

    >>> esp32.cmd('foo()')

    >>> esp32.cmd('x = [1,2,3];my_var = len(x);print(my_var)')
    3

# Soft Reset:
    >>> esp32.reset()
    Rebooting device...
    Done!

PYBOARD (Picocom, Pyserial)

    >>> from upydevice import PYBOARD

# Setup and configurate a device :
    pyboard = PYBOARD('/dev/tty.usbmodem3370377430372') # defaults (serial_port, timeout=1000, baudrate=9600)

# Send command:
    >>> pyboard.cmd('pyb.LED(1).toggle()',100)

    >>> pyboard.cmd("import uos;uos.listdir('/flash')")
    ['main.py', 'pybcdc.inf', 'README.txt', 'boot.py', '.fseventsd', '.Trashes'] # this output is stored in [upydevice].output

    >>> pyboard.output
    ['main.py', 'pybcdc.inf', 'README.txt', 'boot.py', '.fseventsd', '.Trashes']

    >>> pyboard.cmd('foo()')

    >>> pyboard.cmd('x = [1,2,3];my_var = len(x);print(my_var)')
    3

# Soft Reset:
    >>> pyboard.reset()
    Rebooting pyboard...
    Done!

GROUP (to send commands to several devices at a time)

# Setup and configurate the devices :
    >>> from upydevice import W_UPYDEVICE, PYBOARD, GROUP
# PYBOARD
    >>> pyboard = PYBOARD('/dev/tty.usbmodem387E386731342')
# ESP32
    >>> esp32_A = W_UPYDEVICE('192.168.1.53', 'keyespw')
    >>> esp32_B = W_UPYDEVICE('192.168.1.40', 'keyespw')

# Setup and configurate the group:
    >>> my_group = GROUP([esp32_A, esp32_B, pyboard])

# Each upydevice has a name attribute that can be set at creation momment or after
# pyboard = PYBOARD('/dev/tty.usbmodem387E386731342', name='my_pyboard_1'); or pyboard.name = 'my_pyboard_1')
# If not set an automatic name will be set as 'upydev_class'+'ip or serial port'

# Send command:
    >>> my_group.cmd('import machine;import  ubinascii;ubinascii.hexlify(machine.unique_id())')
    Sending command to wupydev_53
    b'30aea4233564'

    Sending command to wupydev_40
    b'807d3a809b30'

    Sending command to pyboard_tty.usbmodem387E386731342
    b'33004e000351343134383038'

# There is an option to silent the group messages with group_silent = True, and or each device ouput with device_silent=True

# Output is stored in group output attribute:
    >>> my_group.output
    {'wupydev_53': b'30aea4233564', 'wupydev_40': b'807d3a809b30', 'pyboard_tty.usbmodem387E386731342': b'33004e000351343134383038'}

# Send command parallel mode **: (experimental mode, may not work 100% of the times, depends on the connection quality (for wireless devices))
    >>> my_group.cmd_p('6*12')
    Sending command to: wupydev_53, wupydev_40, pyboard_tty.usbmodem387E386731342
