M5Atom and StepperMotor

New/Old Stepper Motor

Important Game Changing Features

Here are a some of the most important features:

1. WIFI Interface
2. MQTT Messaging
3. BLE (Bluetooth) interface
4. JSON formated messages (over MQTT or BLE)
5. OTA - Over the Air updates (insitufield updates)
6. Object Oriented Software Architecture (C and C++)
7. Extensible and Adaptable via compile flags (ifdef)
8. Group messaging - permission based shared threads
9. QR Codes (Semantic Marker) in displays for dynamic feedback
10. Node-Red cloud processing (http REST interface)

Over the Air (OTA) updates

A quick update on OTA, this requires a "http" interface (vs https). This means
there must be a server that supports http - which are becoming rare (as https is required for everything.)

We are using kttp://KnowledgeShark.org for this.

Components and Sensors for M5 Family

• Goals is all the sensors and controllers can be configured at RUNTIME vs compile-time.
• Power of the Object Oriented Design
