In the quest to reduce RAM usage with a RAM challenged Arduino device, this blog covers using permanent storage (Flash and EEPROM).

In Part 9 of this series, it was shown how to create a Version 1 table such that the id field is an auto-incremented integer which saves storage space on a small device. Version 1 tables don't automatically save a creation and modification date. This blog covers how to do it with a Script.
The default id field for a Azure Mobile Services Table, that the table is indexed on, is a string. By default the string that is auto-generated is a 36 character GUID string. This can be 3 or more times rest of the data sent as a HTTP Response to a default HTTP GET for each record from the Telemetry table
. This blog discusses this issue and canvasses some options to resolve this overkill.
This blog covers the major revision of the Telemetry
to remove old, now unnecessary code, fix some bugs, further improve error responses, and a stored data structure that makes the parsed JSon data available after the HTTP Response processing is complete.
This blog covers the Stream Parser - State Machine code in detail...
This blog presents a more complete JSon parser in the Arduino context that extracts the data entities from each record. in the JSon string. It is implemented as a Stream Parser - State Machine.
The three TelemetrySensor Arduino apps that mimic the desktop/phone Universal app UI functions are created by copying and appropriately editing the ToDoItem Arduino apps.
This blog presents a simple JSon parser in the Arduino context for the ToDo sketch that extracts the data entities from each record. in the JSon string.
The Universal ToDoItems Microsoft Azure Mobile Services sample app runs on Desktop Windows 8.1, Windows Phone 8.1 and Windows RT. In Parts 3 of this blog, it was demonstrated as to how to action these functions via a command line, using cURL.exe. In this blog we will action those same actions from an Arduino device.
Some hints to do with networking an Arduino device.
