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.

New pictures from the manufacturing process of the tinyK20 boards. Now all parts to be populated have been arrived at the manufacturing, so populating the boards can start soon:

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 :-):
