EzData

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

Example

from m5stack import *
from m5ui import *
from uiflow import *
from flow import ezdata
import wifiCfg

i = None

wifiCfg.autoConnect(lcdShow=False)

while True:
  ezdata.setData('6ijRMmiFRdO2tVfFIbNpy6PN1sRvFmsy', 'my_topic', 'Hello EzData')
  print(ezdata.getData('6ijRMmiFRdO2tVfFIbNpy6PN1sRvFmsy', 'my_topic'))
  for i in range(11):
    ezdata.addToList('6ijRMmiFRdO2tVfFIbNpy6PN1sRvFmsy', 'my_list', i)
  print(ezdata.getData('6ijRMmiFRdO2tVfFIbNpy6PN1sRvFmsy', 'my_list', 0, 50))
  ezdata.removeData('6ijRMmiFRdO2tVfFIbNpy6PN1sRvFmsy', 'my_topic')
  print(ezdata.getCurrentISODateTime())
  wait_ms(2)

API

ezdata.setData('6ijRMmiFRdO2tVfFIbNpy6PN1sRvFmsy', 'my_topic', 'Hello EzData')

• Save Data to the Head of a Specified Topic Queue

print(ezdata.getData('6ijRMmiFRdO2tVfFIbNpy6PN1sRvFmsy', 'my_topic'))

• Retrieve a Data Item from the Head of a Specified Topic Queue

ezdata.addToList('6ijRMmiFRdO2tVfFIbNpy6PN1sRvFmsy', 'my_list', i)

• Save Data to the Head of a Specified Data List

print(ezdata.getData('6ijRMmiFRdO2tVfFIbNpy6PN1sRvFmsy', 'my_list', 0, 50))

• Retrieve a Set of Data from a Specified Data List, with the advantage of list storage being able to specify an offset from the head of the list and retrieve multiple data items at once. Parameters include:
• list: Name of the list (string)
• offset: Offset from the head of the list
• count: Number of data items to retrieve

ezdata.removeData('6ijRMmiFRdO2tVfFIbNpy6PN1sRvFmsy', 'my_topic')

• Delete a Topic or List and Clear Queue Data

print(ezdata.getCurrentISODateTime())

• Get Current ISO Date and Time

ezdata.setDataAsync(ezdata_set_NdmNNcb, ezdata_set_fail_NdmNNcb, '6ijRMmiFRdO2tVfFIbNpy6PN1sRvFmsy', 'my_topic', 'Hello EzData')

• Asynchronous Operation: Save data to the head of a specified topic queue

ezdata.addToListAsync(ezdata_set_iQCwDcb, ezdata_set_fail_iQCwDcb, '6ijRMmiFRdO2tVfFIbNpy6PN1sRvFmsy', 'my_list', i)

• Asynchronous Operation: Save data to the head of a specified data list

ezdata.getDataAsync(ezdata_get_iRBYXcb, ezdata_get_fail_iRBYXcb, '6ijRMmiFRdO2tVfFIbNpy6PN1sRvFmsy', 'my_topic')

• Asynchronous Operation: Retrieve a data item from the head of a specified topic queue

ezdata.getDataAsync(ezdata_get_rfWJMcb, ezdata_get_fail_rfWJMcb, '6ijRMmiFRdO2tVfFIbNpy6PN1sRvFmsy', 'my_list', 0, 50)

• Asynchronous Operation
• Retrieve a Set of Data from a Specified Data List, with the advantage of list storage being able to specify an offset from the head of the list and retrieve multiple data items at once. Parameters include:
• list: Name of the list (string)
• offset: Offset from the head of the list
• count: Number of data items to retrieve

ezdata.removeDataAsync(ezdata_remove_KcMAbcb, ezdata_remove_fail_KcMAbcb, '6ijRMmiFRdO2tVfFIbNpy6PN1sRvFmsy', '')

• Asynchronous Operation: Delete a topic or list and clear queue data

ezdata.getCurrentISODateTimeAsync(ezdata_get_ESdHGcb, ezdata_get_fail_ESdHGcb)

• Asynchronous Operation: Get current ISO date and time
