My Raspberry Pi Zero arrived last week (see “A Raspberry Pi for $5! What are your decision factors?“), and finally I have found an hour to try it out. Because the ‘bare board’ $5 version was sold out at that time, I ordered a package with 8GB SD card, micro USB cable and mini HDMI adapter. That way I had all the needed cables, including the mini HDMI adapter cable:

When I left for the week-end, I missed to take with me my Segger J-Link debug box. I have one P&E Universal Multilink at home, but I needed a Segger J-Link to use the SystemViewer with my robot. I need that for a FreeRTOS trainig I will deliver in Poing/Germany on Monday at Avnet/Silica.
But I had a Freescale KwikStk board at home, and I did remember that I can use that board as a Segger J-Link to debug my custom hardware (see “Freescale Kinetis KwikStik (part 1)“).

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!!!!

It’s not Christmas yet, but: For a research project I’m currently evaluating a new microcontroller where I need a bit more leg room. Right on time I saw that there is a new board available which caught my interest: The Freescale FRDM-K82F :-). Without thinking too much about it, I have ordered that board from Mouser Thursday last week and I had it in my hand today 🙂 Time to put up a quick post about it:
New Box on the table
First off: The tinyK20 project is progressing fine and is now on Hackaday.io :-).
For a research project we would like to use the tinyK20 to log gyro sensor data. For this I have created a quick-n-dirty project to explore how feasible it is. The tinyK20 has all the pins on the outside of the board, so I’m able to put it on a bread board:

One day earlier than expected, our tinyK20 boards arrived, and they are looking great :-):

Over the weekend, I finally have repaired the broken ESC (see “Kinetis Drone: Graupner ESC S3055 Failure“). Time to run some first test flights :-).
Kinetis Drone Flying Tests
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.
