Once you've gotten started, use these simple demos as branching points to extend the system to your use case.

Analog Plotter¶

A custom host-side app that plots analog data using the built-in sensor node app qtpycmd.

•   Analog input
•   Network / MQTT
•   Serial / UART

1. Copy the app's source file analog_plotter.py to your qtpy-preview folder
   • View it in your browser
   • Save-As to download it directly
2. Run it with
   PowerShell

   python analog_plotter.py
   

3. Edit the variables at the top of get_and_plot_data() to exercise the features
   • Note that this example only enables UART communication to start
   • If you setup MQTT to use WiFi, change use_mqtt to True
     get_and_plot_data()

       # Customize
       use_uart = True
       use_mqtt = False
       minimum_mqtt_node_count = 1
       channel_cmd_string = "A0 A3"
       mqtt_group = datatypes.Default.MqttGroup
       max_adc_voltage = 3.3
       max_adc_code = 2**16
