GIGA, How fast do you run?
HTML-код
- Опубликовано: 31 июл 2024
- A quick assessment of the relative speed of the Arduino GIGA R1 WiFi board. Two simple tests for int, long, float and double are performed on a variety of micro-controller boards. The two tests are Eratosthenes and Mandelbrot Set calculations for a very long iterations.
While the M4 co-processor on the GIGA board can run autonomously, in this set of examples, the M7 core is leveraged to capture the timing data from the M4 co-processor for output to the Serial Monitor.
Erratum:
I misspoke: the Sony Spresence has only six cores!
cool video!
Does the Spressence not support Float and Double?
If you could post a video on how to load micropython from scratch that works first time from initial setup. I use Ubuntu, could not get it to work for about a week, what a wate of time on what should be a straight forward process, all the best hardware in the world means nothing if you can not load the software.
The help forums are just as convoluted on this topic.
1. Install dfu-util if not present. Be careful about Windows permissions for dfu-util on GIGA port. 2. Download firmware GIGAR1_MP_FW.dfu 3. Use dfu-util with firmware to flash GIGA for micropython 4. Use recommended IDE (Thonny or Arduino Lab for Micropython whichever you have installed as a prerequisite).
You'll have to re-flash to switch between micropython and Arduino sketches. Status remains constant, however, if the power is switched off-on.
Post any further questions you have and I'll try to find answers for you.
Regards.
Please take a look at ruclips.net/video/EEJB_KGO3DE/видео.html and let me know if you have further questions (I'm having some A/V challenges at my end and therefore I rushed this release). There are a few things I have skipped for now because I would like to do a drill-down in a later tutorial. Regards.
