Space is a hostile environment. Sending hardware to space means putting it under irradiation tests: exposing the object to radiation and see what happens :-). For this, under the lead of the ETHZ (Mathematical and Physical Geodesy), we had the opportunity to put the CubETH payload board under a proton beam. The test facility is at the Paul Scherrer Institute (PSI) in Villigen, Switzerland:
To me, software and tools are by far more important than the microcontroller. Because the silicon is a ‘one time kind of thing’, where the software has to be maintained and working over a longer time. And at least my software usually needs to be ported to a new device, so portability and available software and tools are critical to me.
The combination of MCUXpresso SDK (formerly Kinetis SDK) and Processor Expert is unfortunately not supported by NXP. But I have found a way to get them work together in a nice way, and this article is about making that combination possible :-).
This year I managed to attend the Embedded World in Nürnberg/Germany after missing the 2016 show. And 2017 has been a blast! With more than 1000 exhibitors and >30’000 visitors it was huge! There were too many exciting things, so I just pick a few: NXP demonstrated the new MCUXpresso Software and Tools with a new Eclipse Neon based IDE, lots of IoT and Hexiwear, the tiny LPC800-DIP board, and I have met Alan Hawse in person!
With debugging FreeRTOS applications in Eclipse, it is a big to have views available showing all the threads, queues, timers and heap memory allocation. One of the best Eclipse plugins are the one NXP provides for FreeRTOS: they are free of charge and give me pretty much everything I need. However, if you are not that familiar with FreeRTOS itself, here are a few tips to get more out of the plugins.
I’m pleased to announce that a new release of the McuOnEclipse components is available in SourceForge, with the following main features and changes:
- Wait: Busy-Waiting using ARM DWT cycle counter
- Percepio FreeRTOS+Trace: Updated to version 3.1.1, simplified usage of streaming and snapshot mode
- GenericSWI2C: MCUXpresso SDK can be used with the bit-banging I2C driver support
- FreeRTOS: includes updates of the 9.0.1 release, ‘optimized task selection, enabled MPU support (experimental)
- Graphical GUI drivers for screens, windows, icons, headers, text widgets and more
- SSD1351: display driver for Solomon Systech SSD1351 display
- More components are now supported by the McuLibConfig settings
- Many other smaller bug fixes and enhancements
Questions from students or readers of my articles are a great source for all kind of articles. And here is the ‘question of this week’: “What is realtime debugging”?
It’s a good question because the topic of ‘realtime’ and ‘debugging’ was a topic in the lectures this week. So this question gives me the opportunity to combine the two things of ‘realtime’ and ‘debugging’, I love it :-).
It has been a sleepless night with Föhn wind up to 100 km/h. The compensation for this is a mild temperature of 15°C. Plus that beautiful sunrise this early morning:
Happy Föhnig 🙂
