So Easy MicroPython - Dweet, IoT Cloud Platform

＊＊＊ Just add 2~3 lines, then your MCU will be an IoT enabled device empowered by Dweet.io ＊＊＊

from MyREST_Dweet import myDweet

my = myDweet("YOUR_TOPIC")

my.send({'temperature': 13, 'humidity': 33})

＊＊＊ MyREST_Dweet is a very useful library I designed to let your MCU upload and download data to/from Dweet Cloud platform in very easy and fast way. Just like the codes above, your MCU will send out data of temperature and humidity to Dweet. ＊＊＊

First, You need to upload the libraries to your MCU board：

• MyREST_Dweet: A specific function library for accessing data on Dweet.io platform
• MyWifi: A basic library for WiFi connection (Optional, if your code already make the MCU connect to WiFi)

＊＊＊ If you have no idea how to upload File to your MCU, read my another article "So Easy MicroPython - ESP8266/ESP32 MCU File Management" first.

＊＊＊ If you are interested in MyWifi library or no idea how to use it, read my another article "So Easy MicroPython - My WiFi Connection"

# Connect to WiFi, it cab be omitted if your MCU already get on WiFi in your existing codes

from MyWifi import myWifi

my_wifi = myWifi("YOUR_WIFI_SSID", "YOUR_WIFI_PWD")

my_wifi.connect()

# Only add these 3 lines, then your MCU can upload data in dictionary to the Dweet

from MyREST_Dweet import myDweet

my = myDweet("YOUR_TOPIC")
print('\n >>> Data uploaded to Dweet (can keep in 24 hours):', my.send({'temperature': 13, 'humidity': 33}))

# Connect to WiFi, it cab be omitted if your MCU already get on WiFi in your existing codes

from MyWifi import myWifi

my_wifi = myWifi("YOUR_WIFI_SSID", "YOUR_WIFI_PWD")

my_wifi.connect()

# Only add these 3 lines, then your MCU can read data in list from the Dweet

from MyREST_Dweet import myDweet

my = myDweet("YOUR_TOPIC")

print('\n >>> Read the latest data from Dweet:', my.read())

# Connect to WiFi, it cab be omitted if your MCU already get on WiFi in your existing codes

from MyWifi import myWifi

# Connect to WiFi
my_wifi = myWifi("YOUR_WIFI_SSID", "YOUR_WIFI_PWD")

my_wifi.connect()

# Upload and download data in dictionary to/from the Dweet, and then control the MCU's LED

from machine import Pin

led = Pin(2, Pin.OUT) led.value(1)

from MyREST_Dweet import myDweet

my = myDweet("YOUR_TOPIC")

for i in range(5):

my.send({'led': (i % 2)}) # upload data

res = my.readLast() # download data

if len(res) > 0:

on_off = res[0]['content']['led']

led.value(on_off)
