What To Borg ?

Mats has this cool I2C temprature sensor - just needs a tiny MRL driver.

What thingies do you have which might be Borg'd ?!


More on Attach !

GroG's picture

Ahoy !

We recently were excited to add Java 8 default methods to interfaces for our services ... 
Sadly, this borked Jython :(

But my last checkin should have fixed all that.  There are now no more "default" methods in any Java org.myrobotlab.service interface.

In the process I tried to do some refactoring.  I created a new interface ... "Attachable" !  And moved interfaces which were common to ALL services to org.myrobotlab.framework.interfaces


Jython <---> Java 8 default Interfaces ... No Worky ! :(

I was hoping to wrap up working with the interfaces.  Mats and I made a lot of progress defining how future "attach" will work, and starting to get into the details of implementation.   I have been testing with START_INMOOV.bat script, but now realize there is a rather large issue.

The issue is the new improvement from Java 8 of "default" interface methods are not reachable from Jython !


Service Attaching .... Diving Deeper

We want to build services which can easily be attached.  With simple and consistent rules we can make a platform which supports much more complicated systems.


MotorController is missing an attach !

I'm trying to get Sabertooth service working again .. 
In the process I noticed MotorContoller is missing this method .. 

public void attach(MotorController controller) throws Exception;  

to go along with the other Controller interfaces and to follow the Attach Pattern !


Borg a Furnace

Ahoy !

Recently one morning my wife turned on the furnace and we were quickly inindated with a cloud of smoke.  After the smoke cleared, I looked into the details and found the motor completely burnt.  We purchased a new motor, but in the back of my head I'm always wondering, "How did that happen?"


BoardInfo Bug

Sorry,
I created this one :P

As Calamity pointed out there is some missing runtime type identification of the board, which I recently  commented out. (I owe a unit test ! :P)

Now some history on it :

MRL can now "potentially" compile and upload the board, its necessary to send the correct command line parameters to avrdude.  This is "sort of" done in the ArduinoUtils - but it does not have all the needed types for all the boards.
