In Eclipse and CDT, I need to tell the compiler where it has to search for the header files. The normal way is to go to the compiler settings (menu Project > Properties > C/C++ Build > Settings) and then add the include paths, one by one, using the ‘+’ icon:
Adding Include Path (shown using the GNU ARM Eclipse plugin)
But for many include paths, this is a time-consuming process. But there is another way.
In my earlier post “Tutorial: Web Server with the ESP8266 WiFi Module” I used the ESP8266 WiFi module to run a local web server. This is a cool way to control devices inside my network. But to use that web page from the internet, I would need to open up my router which I don’t want to do for obvious reasons. Why not going the other way: host the web page in the internet, and have my board communicating with that internet page? This is exactly what this hype around IoT (Internet of Things) is all about :-).

Over the last weeks, several contributions, extensions and fixes have been added to the McuOnEclipse components, so a new release is available on SourceForge.
FreeRTOS Tasks Component
In CodeWarrior there was a very useful feature in the CodeWarrior Projects view: with a context menu I can open that folder/file in Windows Explorer:
Show In Windows Explorer in CodeWarrior Projects View
However, this feature is missing in Eclipse, so how to add this functionality?
I want to make some noise with this post!!! This tutorial is about adding music and sound capabilities to the Freescale Freedom board, and to have a lot of fun with it :-). I need this ability for a larger project working on for a while. But I thought I share that sub-part how to play sound files. So with this tutorial I can turn my Freescale Freedom board into a music or sound player :-). And adding sounds is a cool way for any project, and as the music is stored on an SD card it fits easily hours of music or sounds.

From time to time it is good to do some cleanup work: what has grown organically sometimes needs some cuts and moves. The same applies to the McuOnEclipse GitHub repository (https://github.com/ErichStyger/mcuoneclipse) which has grown to 522 MByte, 8364 files and 1444 folders. I already moved out the Processor Expert component releases (see “McuOnEclipse Releases on SourceForge“). Time to cleanup and move something else: the Processor Expert component sources.

I have several applications where I store application specific information in the microcontroller FLASH memory (see “Configuration Data: Using the Internal FLASH instead of an external EEPROM“). I have run into issues recently with the Segger J-Link GDB server as by default it does *not* erase all the FLASH memory. So the question is: How can I erase all (or part) of the FLASH memory with GDB (e.g. in Kinetis Design Studio or in Eclipse)?

For me as an Eclipse and Processor Expert lover, a press release that Atollic supports Processor Expert catched my eye :-). So there is yet another way to use Processor Expert: with a commercial Eclipse IDE provided by Atollic (atollic.com/).

Time to check it out…
The Freescale FRDM-K64F and FRDM-K22F have a different OpenSDA (v2) firmware on it: unlike the earlier (v1), that firmware is open and not protected which is a great thing. However, it has the disadvantage if you use the wrong SWD/JTAG header on your board, the bootloader on the K20 OpenSDA microcontroller is gone 😦

I happily used the Keil v4.71.2.0 μVision tools for a few small projects (see “Using Keil µVision (ARM-MDK) with Processor Expert Driver Suite“) with the ‘lite’ edition (32kByte code size limitation). This weekend I wanted to move to the new v5.12.05 version.

And there were indeed several things which are different. So this is post is about getting this version getting up and running as the v4.7 one.
