Yocto-Display module configuration.
Firmware
The module firmware can easily be updated with the help of the interface. Firmware destined for
Yoctopuce modules are available as .byn files and can be downloaded from the Yoctopuce web site.
To update a firmware, simply click on the
upgrade
button on the configuration window and follow the
instructions. If the update fails for one reason or another, unplug and re-plug the module and start
the update process again. This solves the issue in most cases. If the module was unplugged while it
was being reprogrammed, it does probably not work anymore and is not listed in the interface.
However, it is always possible to reprogram the module correctly by using the
Virtual Hub
software

Logical name of the module
The logical name is a name that you choose, which allows you to access your module, in the same
way a file name allows you to access its content. A logical name has a maximum length of 19
characters. Authorized characters are
A
..
Z
,
a
..

,
0

_
, and
-
. If you assign the same logical name
to two modules connected to the same computer and you try to access one of them through this
logical name, behavior is undetermined: you have no way of knowing which of the two modules
answers.
Luminosity
This parameter allows you to act on the maximal intensity of the leds of the module. This enables
you, if necessary, to make it a little more discreet, while limiting its power consumption. Note that this
parameter acts on all the signposting leds of the module, including the Yocto-led. If you connect a
module and no led turns on, it may mean that its luminosity was set to zero.
Logical names of functions
Each Yoctopuce module has a serial number and a logical name. In the same way, each function on
each Yoctopuce module has a hardware name and a logical name, the latter can be freely chosen by
the user. Using logical names for functions provides a greater flexibility when programming modules.
The functions provided by the Yocto-Display module are
display
, corresponding to the screen,
anButton1
to
anButton6
to manage the potentiometer inputs, and
files
corresponding to the file
system.
