Really simple IoT writer tool - adding data bursts, named fields and efficency option

Ahora está siguiendo esta publicación

Writing data from Matlab to ThingSpeak.com is extremely easy (type "doc webwrite" in matlab and check the first example). This class adds three features: (1) Fifo for short bursts of data beyond the 15 s limit (2) An optional powershell script that brings down write time from an unpredictable 0.35-5 seconds to a known 0.035 seconds on any connection. (3) The general ease of working with an object. You see directly what you can do and how to do it.
Example 1 - Minimal:
================
t = thingSpeakWriterClass('8Y3SNIGB3MDGCDUJ');
t.write([1,2,3]);

Example 2 - Named fields:
====================
t = thingSpeakWriterClass('8Y3SNIGB3MDGCDUJ');
t.readFieldNames(45789); %Read and display the channel setup from thingspeak.com
data.Appetite = 5;
data.status = 'Bring me pizza or you shall...';
ok = t.write(data); %ok <= 0 on fail. = entryID on success.

1.4.0.0

Added white space in description (how hard can it be)?

1.3.0.0

Just edited the description

1.2.0.0

Version 1.2 allows writeMode = 'powershell' to write:
data.status = 'PS ok: !"#¤%&/()=?´´@£$€{[]}\+;:,.-_<>|§½¨^~''*'
Characters '"\;#&' are silently removed and the rest is passed on.
OBS! The standard writeMode = 'webwrite' writes any string.

1.1.0.0

Fixed a couple of typos in the documentation and added a new example
