My favorite projects are always related to the "latest" tech in command and control, networking and network communications. This Elecrow GSM/GPRS/EDGE SIM5360E 3G Shield seems to be the "latest and the greatest" as far as 3G and GPS, as far as I can see so far, but I has it drawbacks for sure.... (6 Replies)
Today I received my NB-IoT Arduino Shield for AIS (Thailand). Here is a "pinout" photo of the shield.
My shield looks just like the one above, for the most part. I'll post another photo of the actual device later.
When I received the shield in the mail, I went immediately to a local... (8 Replies)
Normally I have very good experiences buying from AliExpress, but in this case with Elecrow, I'm disappointed.
After confirming with Elecrow on AliExpress that their Elecrow GSM/GPRS/EDGE SIM5360E 3G Shield for Arduino would work with 3G SIM cards in Thailand, I purchased one. My plan was to... (1 Reply)
Here is a sketch to do basic testing for the Arduino UNO and the MLT-BT04.
This BLE module works with IOS (iPhone) and I'll add some details on my IOS testing with an iPhone in a follow-up post.
For now, here is the basic BLE (HM-10) sketch for the Arduino UNO:

The result turned out nice, I think. I like the look and... (10 Replies)
Normally I'm not into kits, but I thought my wife would enjoy this one since she is a big fan of robots and droids on StarWars!
We are done with the basic mechanical assembly and starting on the electronics assembly today.

Font::TTF::GDEF - Opentype GDEF table support
DESCRIPTION
The GDEF table contains various global lists of information which are apparantly used in other places in an OpenType renderer. But
precisely where is open to speculation...
INSTANCE VARIABLES
There are up to 5 tables in the GDEF table, each with their own structure:
GLYPH
This is an Font::TTF::Coverage Class Definition table containing information as to what type each glyph is.
ATTACH
The attach table consists of a coverage table and then attachment points for each glyph in the coverage table:
COVERAGE
This is a coverage table
POINTS This is an array of point elements. Each element is an array of curve points corresponding to the attachment points on that
glyph. The order of the curve points in the array corresponds to the attachment point number specified in the MARKS coverage
table (see below).
LIG This contains the ligature caret positioning information for ligature glyphs
COVERAGE
A coverage table to say which glyphs are ligatures
LIGS An array of elements for each ligature. Each element is an array of information for each caret position in the ligature (there
being number of components - 1 of these, generally)
FMT This is the format of the information and is important to provide the semantics for the value. This value must be
set correctly before output
VAL The value which has meaning according to FMT
DEVICE For FMT = 3, a device table is also referenced which is stored here
MARKS
This class definition table defines the classes of mark glyphs that can be selected for processing using the MarkAttachmentType field
of lookup FLAG words.
MARKSETS
Contains an array of coverage tables indexed by the FILTER value of a lookup.
METHODS
$t->read
Reads the table into the data structure
$t->out($fh)
Writes out this table.
$t->update
Sort COVERAGE tables.
