EzData 2.0

EzData 2.0 is an IoT cloud data storage service provided by M5Stack, allowing different devices to insert or extract data into a storage queue through a unique token, enabling data sharing.

Example

import os, sys, io
import M5
from M5 import *
from ezdata import *

ez_0 = None
ez_item = None

def setup():
  global ez_0
  M5.begin()
  Widgets.fillScreen(0x222222)
  ez_0 = EzData('b1112ac5e9644f26af381c15c4a0e1da', 'age')
  ez_0.set("res/img/default.png", is_file=True)

def loop():
  global ez_0
  M5.update()
  ez_0.set(18, is_file=False)
  print(ez_0.get())
  ez_0.set([1, 2, 3], is_file=False)
  print(ez_0.history())
  ez_0.delete()
  for ez_item in get_key_list(device_token=_).iterms():
    print(ez_item[0])
    print(ez_item[1])

ez_0 = EzData('b1112ac5e9644f26af381c15c4a0e1da', 'age')

• Initialize EzData, optionally filling in the online device token and the corresponding key to access.

ez_1 = EzData('b1112ac5e9644f26af381c15c4a0e1da', 'hello_M5')

• Initialize EzData, customizing the device token and the corresponding key to access.

ez_4 = EzData('b1112ac5e9644f26af381c15c4a0e1da', '', public=True)

• Initialize EzData, customizing only the device token.

ez_3 = EzData('795efd86c2a6478eb9c3bb414376bb6b', 'age')

• Initialize an EzData dataset object, optionally filling in the device token and the corresponding key to access.

ez_0.set(18, is_file=False)

• Modify the value corresponding to a specified key.

ez_0.set({'hello_M5':'hello M5'}, is_file=False)

• Save a data Value to the value corresponding to a specified key.

ez_0.set([1, 2, 3], is_file=False)

• Save an array list to the value corresponding to a specified key.

ez_0.set({'hello_M5':'hello M5'}, is_file=False)

• Create an array map, and save the array map to the value corresponding to a specified key.

ez_0.set("res/img/default.png", is_file=True)

• Customize an image resource file and upload it to the value corresponding to a specified key.

ez_0.set("res/img/default.png", is_file=True)

• Select an image resource file to upload to the value corresponding to a specified key.

ez_0.get_file('helloM5.png')

• Update an image resource file to the value corresponding to a specified key.

print(ez_0.get_update_time())

• Retrieve the last update time of the data.

print(ez_0.get())

• Retrieve the data Value corresponding to a specified key.

print(ez_0.has_new_data())

• Retrieve the latest data corresponding to a specified key.

print(ez_0.history())

• Retrieve the historical records of data corresponding to a specified key.

for ez_item in get_key_list(device_token=_).iterms():

• Iterate through all lists in the EzData object.

print(ez_item[0])

• Retrieve all keys corresponding to the EzData list being iterated through.

print(ez_item[1])

• Retrieve all data values from the list corresponding to a specified key.

ez_0.delete()

• Delete the key object corresponding to the current device's EzData.
