If you are a frequent reader of this blog, then you know: I’m a big fan of Processor Expert components. While there are many Processor Expert components delivered with CodeWarrior, it lacks many components and device drivers beside of the normal on-chip peripherals. But value gets added to an embedded project with all the external devices, sensors and actuators. That’s why I have created many more components which are available on my GitHub site. Readers of this blog have asked several times to create a tutorial on how to create a Processor Expert component. So why not working on that on a long Easter weekend full of cold rain and snow?
Many times I have Processor Expert components carefully configured in one project, and then I want to have the same thing in another project. There is actually an easy way to carry out this: to copy components from one project to another.
Using a version control system for software development is a standard procedure today. While things are pretty clear for ‘standard’ Eclipse projects, it is not that easy for Processor Expert projects. I’m using Processor Expert projects with Git and SVN (Subversion). I want to share here tips how to use Processor Expert projects with a version control system. Screenshots and vocabulary are for TortoiseGit and Git, but applicable to any other VCS (Version Control System).
- For dead-end paths, instead turning around, the robot is driving backward
- Higher speed for going forward/backward/turns
- In the finish area, the robot turns around
- It reverts the solution path, so the robot can directly run from the finish area to the start
For many of my applications I’m using a PWM (Pulse Width Modulated) signal. One example is the motor driver used in this project where I use one PWM signal for each motor. Another usage of PWM is to control the brightness of an LED. Processor Expert makes usage of the PWM hardware easier. Still, for some settings it is good to have the resulting signals in mind. So in this post I’m showing how the settings impact the PWM signal generated.
Sometimes I’m looking for a functionality, and I cannot find it. But this does not mean that it does not exist ;-).
The Eclipse preference pages have a great filter text field: If I want to change a setting which has something to do with ‘color’, I can enter that text and it will show me all setting pages having something to do with ‘color’:
