Part 2: Barbecue Beef Brisket Texas Style – The Rub

It’s 5:15am, and started the fire in the smoker. Until it warms up, time to apply the rub to the brisket.

I have learned that Brisket is the national food of the Republic of Texas. I decided that this time I will do the rub differently: salting the meat the day before (see “Part 1: Barbecue Beef Brisket Texas Style – The Meat and the Salt“), and applying the rub (without any salt) just before putting the meat into the smoker. I’m using a variation of Texas “Dalmatian Rub”: salt (applied before), coarsely cracked black pepper with a few spices.

Translating for the world …

English is not my first language, but I use it in this blog because that way I can reach a broader audience. If I would use Swiss German, only a few would be able to understand what I write about: “Wänn I würd schwiizerdütsch bruuche, dänn chönt wohl chuum öpper das hie läse” ;-).

Google Translate is not prefect, but still it does a fair job of translating web pages. I have added now a Google translate button to this blog side bar. Click on it and have the web page translated to the language of your choice. Try it out:

Happy Translating 🙂

PS: some of the translations by Google are sooooo funny 🙂

Sneak Preview: Profiling Bare Metal Microcontroller Applications with GNU gprof

I’m working on a conference paper and presentation, and tonight I had a break-through :-). So how cool is this: Profiling with GNU gprof a bare-metal embedded Cortex-M application (Freescale Kinetis K64F running the Freescale Kinetis SDK) in Eclipse:

Revert an Eclipse Update Installation

I’ve been running into an issue with an Eclipse plugin update: I updated a plugin, and then broke a critical functionality. What I usually do is to uninstall the plugin (see “Uninstalling Eclipse Plugins“), and then install it again. However, in this case the uninstall ended with an error too :-(.

Uninstall failed

What now? How can I revert that plugin installation/update?

Grand Prismatic Spring

The Grand Prismatic Spring is the largest and one of the most brilliant of the many springs in Yellowstone. The temperature of the water is around 60°C. The yellow, orange and brown colors are caused by small heat-loving microorganisms, names thermophiles. The intense blue color in the center is because of the sunlight gets scattered by fine particles in the water. Simply beautiful!

Happy Heating 🙂

I worked the past weekend and nights using the Freescale FRDM-K64F board with the colorful Adafruit NeoPixels (see “Tutorial: Adafruit WS2812B NeoPixels with the Freescale FRDM-K64F Board – Part 1: Hardware“). These RGB LEDs can create beautiful colors. For for the non-geeky readers I have a more ‘natural’ one:

The beautiful colors in Yellowstone National Park (USA) are the result of pigmented bacteria that grow around the edges of the mineral rich water. I very much enjoyed it a few years ago, cannot wait to get back there.

Happy Coloring 🙂

Tutorial: Adafruit WS2812B NeoPixels with the Freescale FRDM-K64F Board – Part 5: DMA

This is Part 5 of a Mini Series. In Part 4, I described how to set up the FTM (Kinetis Flex Timer Module) to generate the required waveforms used for DMA operations (see “Tutorial: Adafruit WS2812B NeoPixels with the Freescale FRDM-K64F Board – Part 4: Timer“). In this post I describe how to use to trigger DMA (Direct To Memory) events. The goal is to drive Adafruit’s NeoPixel (WS2812B) with the Freescale FRDM-K64F board:
