Blinkit v2.3 | Blink Logitech devices on Steem actions

With this new update of Blinkit it is possible to blink Logitech devices on new Steem actions such as upvotes and followers.

The Blink properties can be set and saved from the blinkit interface: Number of blinks, blink delay, and the blink colour.

The Logitech brand is probably the most famous, input device manufacturer in the world, and chances are that you are using there product right now.

Some of there products, and specialy there Gaming line have (RGB) LEDs inside them and Logitech made it possible for 3rd party developers to interact with those (RGB) LEDS.

 
 

Blinkit can now be used to blink Logitech devices on Steem related action

Integrating support for Logitech devices in Blinkit

Some time ago i had contacted @flash4yard, because he made a Steemit post about his work to make the Logitech keyboard Blink with Visual Basic, Blinkit is made with VB as wel and after getting in contact we agreed on working together to integrate it into Blinkit. below a list of the newly supported Logitech devices.

The following Logitech devices are now supported:

Keyboards

G910 Orion Spark
G810 Orion Spectrum
G610 Orion Brown
G710+
G510/ G510s
G110
G19 / G19s
G105 / G105 Call Of Duty

G15 v1 / v2

 

Mice

G900 Chaos Spectrum
G303 Daedalus Apex

 

Headsets

The supported devices make use of the Logitech Gaming Software

 
 

Blinkit new features:

• New device button for Logitech is added to the mainscreen of Blinkit
• Logitech device screen is added with its related buttons and pull-down elements.
• Logitech blink script
• Variable Path to the Logitech Gaming Software DLL

Logitech blink window

To be able to stop/close the blink action before it's finished this window is open (minimized) when a blink action takes place. The user can click on the window, and can close it to stop the blink action.

 

 

How is it implemented

 

Blinking the leds

To be able to turn on the leds of the supported Logitech devices, the by logitech's driver provided DLL is used to be able to blink the leds. The Logitech backend code is made by @flash4yard with the needed specifications for Blinkit in mind, please check his post for more details on his work for this integration. To make it work with Blinkit we tested it on multiple systems.

To let the interface communicate with the backend the following code is added to Blinkit.

 

Loading the by Logitech pre-installed DLL into logitechblink.exe to be able to communicate and blink the Logitech device.

 

Bat scripts

The batscripts that look for new Upvotes, Followers and new Post have been added and updated to call the logitechblink.exe on new found actions.

Interface

Dropdown boxes, and buttons are added that gives the user the possibility to set and save the colour and blinking properties, the values are saved in the blinkit config folder. and used by the front and backend. When Blinkit is restarted, the previously saved values wil be preloaded.

The following files have been updated/added:

• Blinkit.exe
• upvoteslogitech.bat (look for upvotes and Blink the Logitech device when one is found)
• followerslogitech.bat (look for followers and Blink the Logitech device when one is found)
• postslogitech.bat (look for new posts and Blink the Logitech device when one is found )
• logitechblink.exe (send the blink command with it's blink properties to the keyboard)
• logitechblinkVBcode.txt (code from logitechblink.exe)

 

The Blinkt repository is updated

The Blinkit source files repository is updated

 

 

Testing and improvements

This is the first integration for Logitech devices into Blinkit, the functions are tested with 3 different keyboards, and on 4 different machines. by me and @flash4yard and @dmxmaster.

The G510 is used for testing on two different systems and works flawless

There is a problem with the older G15 v2 monochrome keyboard where it wont light up on request made to it. (Although the provided Logitech LED Emulator software is showing the blink action is working for all supported devices and should also be working on these monochrome keyboards, it wont.

The by Logitech provided documentation explains that the devices will function equally independent of it monochrome or RGB features, they all use the same DLL, and the same requests, therefore the problem with the G15 v2 most likely is because that model is one of the older devices that is/should be supported, and would turn as stated in the manual, it would turn the RGB request into a monochrome request... but that's not happening. We have spend to much time to figure out what the problem could be, online documentation is hard to find for this older model. Things tried: reinstalling, installation / connecting order, other system, older versions of the driver, dll and Logitech Gaming Suite, all did not fix this issue and this keyboard doesn't allow no new firmware to be installed on it. Suggestion are very welcome!)

If you have one of the supported device, and want to help out with testing it would be much appreciated.

 

Things to improve in a next update for Logitech devices:

• LCD display support (display text on the supported devices that have a display)
• Colour pick wheel to let the user choose any possible colour
• Fading
• List connected and compatible Logitech devices
• Change the product picture displayed in the Logitech device window based on the connected and compatible device.
