Annex Wifi/ uMite

In this project Annex Wifi for the ESP8266 is providing a WiFi interface for a uMite MX170 running MMBasic. This firmware (esp-mcu2.2, currently) has been re written from the original ESP basic version (described here),  The addition of Annex WiFi  to the powerfull uMite controller has provided far more functions than the original version whilst reducing the size of firmware in the ESP8266 and uMite.

While not a complete list some of the features of this combination are:

  • Makes a Read/Write SPIFFS File system available to the MX170 micro
  • HTTP Network Messaging/Commands
  • UDP Network Messaging/Commands
  • UDP device discovery
  • Email messaging for the uMite
  • Expandable to suit specific requirements.
