It was again one of these Sundays: I’m stuck in dense fog down in the valley, but getting up a few hundred meters things are inverted:
Off-Season Flowers

We had three times snow this Fall time, but nature thinks it is not Winter time yet?.At least some flowers at 1100 m above Sea level have skipped Winter time already ….
Tutorial: Playing MP3 Files with VS1053B and FRDM Board
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.
Engineering Joke of the Week: The Genie
Three men: a project manager, a software engineer, and a hardware engineer are helping out on a project. About midweek they decide to walk up and down the beach during their lunch hour. Halfway up the beach, they stumbled upon a lamp. As they rub the lamp a genie appears and says “Normally I would grant you three wishes, but since there are three of you, I will grant you each one wish.”

McuOnEclipse Component Sources in Dedicated GitHub Repository
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.
Updated McuOnEclipse Components: USB for KL24Z, FatFs v0.10c, Shell Backspace and FreeRTOS Trace Hook Configuration
I have received several requests to post a quick note when there is a new release (16-Nov-2014) of the McuOnEclipse components on SourceForge (see “McuOnEclipse Releases on SourceForge“). I have published today a new release, and with following major improvements:
- USB support for Kinetis KL24Z
- FatFs now features the latest Elm-Chan v0.10c release
- Backspace support in Shell
- Configuration item in FreeRTOS for Percepio Trace Hooks
Tutorial: How to Erase the FLASH with the GNU GDB debugger
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)?
Engineering Joke of the Week: The Train Ticket
On a train to a large computer convention, there was a bunch of engineers and a bunch of managers. Each of the managers had a train ticket. The group of engineers had only ONE ticket for all of them. The managers started laughing, figuring the engineers were going to get caught and thrown off the train.
When one of the engineers, the lookout, said, “Here comes the conductor,” all of the engineers went into the bathroom. The managers were puzzled.

Adding Processor Expert to Atollic TrueSTUDIO
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…
