The bad news: my ESC (see “Kinetis Drone: Graupner ESC S3055 Failure“) for my Kinetis drone is still not repaired :-(. Anyway, I have plenty of other things to make for my drone project. One is to work on the remote controller:

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.

The manufacturing of 200 tinyK20 board is progress, and I’m sharing pictures of it :-).

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.

On SourceForge I have published an update of the McuOnEclipse software components, with following major changes:

How about to use the Freescale FRDM-KL43Z board (see “Unboxing the Freescale FRDM-KL43Z Board“) to play a Tetris game?
I won’t be able to attend the Maker Faire in Rome (16. – 18. Oct. 2015). But five of the Sumo bots students from the previous semesters have built and programmed will be there.

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:

Probably for cost reasons, the Freescale FRDM-K22F does not come with the micro SD card socket populated on the the board:

With a little soldering skills it is possible to populate the socket so the board can be used with a file system on it :-):

It is possible to use the Freescale FRDM-KL43Z to debug another board (see “Using the Freescale Freedom (FRDM-KL43Z) to Debug other Boards“). The FRDM-KL43Z has an on-board debug probe integrated, the OpenSDA. But it is easily possible to debug the board directly with a SWD debug probe like the P&E Universal Multilink or the Segger J-Link.
