A Raspberry Pi for $5! What are your decision factors?
It it is obvious that a new trend from the US is swapping over to Europe and probably the rest of the world: Black Friday. That is the day yesterday following Thanksgiving day in the United States. It is a ‘shopping’ day. Consequently, the stores are battling with huge discounts. And I use that to fill up my inventory for the Christmas-time projects 🙂 What caught my attention yesterday Friday was this: a Raspberry Pi Zero for US$5!!!!

McuOnEclipse Components: 22-Nov-2015 Release
A lot of good things happened in the last three weeks, so here is a new updated McuOnEclipse component release, with the following main improvements:
- Updated Segger RTT component
- New Segger SystemView component
- FreeRTOS ‘tasklist’ shell command
- FreeRTOS with support for Segger SystemView
GNU gcc printf() and BuiltIn Optimizations
Readers of my blog know: I’m not a fan of printf(), and I think for many good reasons. Still printf() is widely used, and the GNU gcc tries to optimize things. This is observed with a simple example: If I’m writing
printf("a");
Then the code produced (ARM Cortex-M0+ with GNU ARM Embedded 4.9 2015q2 gives:
movs r0, #97 ; 0x61 bl 0xa98
Instead of calling printf(), it is calling putchar()! Why is that?
PutChar instead of Printf
Tutorial: lwip with FreeRTOS and the Freescale FRDM-K64F Board
This tutorial is about how to create a lwIP project with FreeRTOS using the Kinetis SDK V1.3.0 with Kinetis Design Studio on the Freescale FRDM-K64F board.

Overview: Processor Expert
In “Overview: From Snippets to Code Generation” I discussed several tools used in my development process. On tool which helps me a lot to get things done is Processor Expert. In this post I’ll give an overview about this tool and reasoning for the pros and cons of using it.

Playing Tetris with a FRDM-KL43Z Board
How about to use the Freescale FRDM-KL43Z board (see “Unboxing the Freescale FRDM-KL43Z Board“) to play a Tetris game?
Kinetis Drone: Sensor Fusion Toolbox
Flying a quadrocopter without some sensor and microcontroller intelligence will be a challenge. Definitely I will need some intelligent sensor data to help me out :-). Luckily, there is a Freescale ‘Sensor Fusion Toolbox’ and Library which gives me a nice start and visibility into the sensors I plan to use:

Aligning S19 Records to 64-bit Boundaries
Many tool chains and linker are able to produce S19 files, such as with the GNU tools it is the ‘objcopy‘ which does this job (see “Binary (and S19) Files for the mbed Bootloader with Eclipse and GNU ARM Eclipse Plugins“). But these tools usually cannot handle the special cases. For example on the Freescale Kinetis K64F my serial bootloader (see “Serial Bootloader for the Freedom Board with Processor Expert“) had a problem with these lines in the S19 file:
Not aligned S19 file entries
Freescale CMSIS-SVD Register Files with Eclipse MARS and EmbSysRegView
In “How to Add Register Details View in Eclipse” I showed how to add the Register detail support in Eclipse using the EmbSysRegView plugin. This was for Luna/Mars, and for the version v0.2.4 of the plugins.
Since then, there is a new version of Eclipse (MARS, see “Going to Mars: Building a DIY Eclipse IDE for ARM Embedded Microcontrollers“) and the EmbSysRegView plugin has been updated to v2.0.5. Makes everything much simple, so here is an updated post with the details how to add register detail view to Eclipse Mars.
