A week ago, the updated FreeRTOS V7.5.0 has been released on FreeRTOS.org. So time to have my Processor Expert FreeRTOS component updated as well :-).

How to re-enable ‘Add to dictionary’ for the Eclipse Spell Checker
I love to have my sources ‘warning free’, so I spend an extra effort to have things clean and the way the compilers like it. In a similar way, I want to have my source comments spell-error free :-). For this, I love the Eclipse spell checker (see this post) which offers to add unknown words to the dictionary:
Add word to dictionary
But what if that ‘Add’ action is missing? How to re-enable it?
DIY Free Toolchain for Kinetis: Part 3 – Debugger (GDB Server with P&E and Segger)
This is the third part of a tutorial series how to ‘do-it-yourself’ a tool chain for the Freescale Kinetis microcontroller, with the FRDM-KL25Z as example. The tool chain is using GNU ARM gcc plus Eclipse Kepler release. So far I have the following parts:
List of Tutorials
- Part 1: Setting up ARM GNU tool chain
- Part 2: Setting up Eclipse IDE
- Part 3: Setting up the debugger (P&E and Segger)
- Part 4: Setting up Processor Expert
- Part 5: Setting up FreeRTOS Kernel Awareness
- Part 6: Linux Host Support with OpenOCD and CMSIS-DAP
- Part 7: GNU ARM Eclipse Plugins
- Part 8: Processor Expert with GNU ARM Eclipse Plugins
- Part 9: DIY Free Toolchain for Kinetis: Part 9 – Express Setup in 8 Steps
- Part 10 – Project Creation with GNU ARM Eclipse 2.1.1
So far things are very generic. But with debugging it means different hardware, and different hardware connections. And for this connection we need a GDB Server.
GDB Server
Eclipse CDT features a GNU Debugger (GDB), and this is what I want to use here: debugging my microcontroller with GDB inside Eclipse. In order to debug the microcontroller, I need two other things: a GDB Server and a Debug Probe.

USB MSD Host for the FRDM-K20D50M Board
The Freedom boards FRDM-KL25Z RevE and FRDM-K20D50M make it easier to use it as USB Host device, as they come with a special jumper to provide 5V to the USB device, so my earlier ‘hack’ is not needed any more :-). After I had USB MSD Host working for the FRDM-KL25Z, it was much harder to get the USB stack working for the FRDM-K20D50M board, because somehow the example Freescale provided with their USB stack refused to work properly on my board. After debugging it for several nightly hours, I decided to take my working Processor Expert project for KL25Z and added support for the K20. And the good news is: since tonight this is working :-).

Using the FRDM-KL25Z as USB Keyboard
I miss my old DELL laptop. Ok, the new one I received from IT services is not bad. It is faster and has a better screen. But I’m not really happy with the new keyboard. With the previous keyboard I was able to do a ‘PrtnScrn’ with a single key press. With the new one I need to press Fn + PrntScrn. And this is impossible to do with one hand:
Impossible to reach Fn+Prnt Scrn with one hand!
Yes, I have two hands ;-). But many times I need to do ‘print screen’ while having my other hand on the mouse :-(.What else can I do?
Using the HC-06 Bluetooth Module
After my first post using a Bluetooth module, things have evolved a bit. The challenge with these Bluetooth modules is: they look the same, but having different firmware. I did not fully realize that until I have ordered another bluetooth module from dx.com:
DX.com Bluetooth Module (HC-06)
That module comes already on a carrier, so I assumed I can use the same driver as for my other module. I was wrong :-(.
Eclipse Problems View: Only Show Problems for Project
Having many projects open the same time, and working on them in parallel is a challenge. Ok, the human brain is not built for multitasking, but I still try ;-). What I typically I end up in my Eclipse Problems View to have entries from multiple projects mixed up:
Problems View with Entries for multiple Projects
How to show it that I can fix the problems for ony project only, and not showing all problems from all projects?
Traps and Pitfalls: No Hex/Bin/S19 File Created with GNU?
I stumbled now twice over a problem, and only after a lot of head scratching (you should see my head now 😉 ) I have found the cause (and solution) for it. In the hope that I can save the readers of this blog some time, here is what happened.
I described in earlier posts how to enable GNU build tools to generate hex/bin/S19 files, or to write the code size to the console view. That works fine for me. But then I received a project were obviously this does not work: even with the project settings configured properly, there is no S19 file, and no code size printed. What’s wrong?

Tutorial: Arduino Motor/Stepper/Servo Shield – Part 1: Servos
This post starts a small (or larger?) series of tutorials using the Arduino Motor/Stepper/Servo Shield with the FRDM-KL25Z board. That motor shield is probably one of the most versatile on the market, and features 2 servo and 4 motor connectors for DC or stepper motors. That makes it a great shield for any robotic project :-).
