New overlay filter.  Thanks to astro for the idea and Mats for the direction :)

AdafruitMotorShield - what the what ?

GroG's picture

I'm running the Test service which whips the auto-magic elves into looking in every nook & cranny for little bugs.  They found lots hiding in AdafruitMotorShield.  

I don't think its worked for years :P 

It relied on code being "injected" into MrlComm before being compiled and uploaded.  It also required the AdafruitMotorShield library to be included/compiled into the upload.

So how to get AdafruitMotorShield worky ?

As I'm trying to polish up Sabertooth, Joystick, and provide an interface in python you can do this

motor.attach(joystick.getAxis("y"))

I noticed MotorControl has getPowerLevel() & getPowerOutput()

Dom wants to use A6 & A7 on the Nano

I'm about to add the 2 pins in the Arduino service pin definition for the Nano .. but what are the "real" addresses of these pins ?

They are not listed on any documentation .. I found this excellent description regarding these mysterious and silly pins on the Arduino forums..


How to make a Post with an embedded Python script

Hi, when you write a post, you may want to reference a script in pyrobotlab. To reference a script, you just need to put the path to the script it in brackets.

For example :

if you have a python script in the pyrobotlab repo, you would write

[[ home/Ray.Edgley/wksr.py ]] and the following script would show up

[[home/Ray.Edgley/wksr.py]]
