Re: MicroPython Newsletter Issue 1

I see there are several variants of the Cypress CYW4343. They seem to have STM32F cores. Are we right to assume the Bluetooth chip will also run micropython, or will it be dedicated to the comms task ? - https://community.cypress.com/community/wiced-wifi/wiced-wifi-partners stm32F411, F412, in 100MH...

Re: MicroPython Newsletter Issue 1

This is great news. I sure hope you can keep the price down. Maybe options for what's populated ?
Would love to see Kwabena et al be able to use the board and maybe have input if they need something.

Re: graphing the memory map

Ressurecting ancient thread. My code now online in repo here: - https://github.com/Neon22/micropython-examine-mem-maps I finally got D3 to play well. Thanks Firebug. Code is still not in very good shape but now works for memory sizes (no symbols yet). See repo readme for more details To play: - down...

Re: MicroPython and the European Space Agency

Congratulations to Damien, and the rest of the team working away on the ports (like Paul S and Dave H). This is fantastic news. Well done.

Another kickstarter

Another project currently on Kickstarter is capable of running micropython.
It needs the esp8266 port and they have said they will consider including it in their system if the port is completed.

Re: graphing the memory map

Its in two parts - one is python code (of course) which is parsing the .map files and generating a csv (maybe json - we will see) file. This is then embedded in an html page (to avoid sec XSS issues) and displayed in any browser (but IE is NG as usual). The display technology is D3 a javascript data...

Re: graphing the memory map

Using D3 for graphing. What a cool javascript library. I'm going to be out of touch for almost two weeks. Here's progress: - parsing one format of .map file - not yet parsing the msvc version but not expecting any problems with it. (thanks @stijn for samples) - extracting all top level regions and p...

graphing the memory map

The .map file shows how much memory is used in the RAM and ROM. It is generated when a build is compiled. This is useful to see how much memory space a build uses and especially useful to see how much space is left over for a specific board implementation. (Perhaps not so useful for Unix.) I am writ...

DMA, SPI and WS2812B

I see this approach on controlling sequences of the WS2812B RGB LEDs. The clever part is usuing the DMA to push the pattern out to the strip of LEDs without CPU overhead. Leaving the CPU to make pretty patterns. http://blog.gitmi.com/interfacing-ws2812b-ws2811-rgb-leds-with-a-pic32mx-250f128b-micro-...

Re: Irregular processing power

@fma do you have an metrics on what the effect of adding LEDs is ?
How many can be added ?
How is the speed affected ?
If you're sending a visible 'pulse' down a string of LEDs - what kind of duration are we talking about ?

I hope you don't mind me asking these questions :)
