Re: Including binary libraries - experiment in teaching

<...> I'm wondering how to do this within the Arduino IDE. Its usual mode is to have all source code available, but that would defeat my purpose. I suppose I could create a bunch of alternative 'target board' builds, but is there an easier way? Any suggestions? <...> From my (very) limited understa...

Re: massively parallel stm32duino blue pill

The $5 per node RPi Zero is the least expensive commercially available microprocessor per-node implementation I have seem built into a cluster. The implementation is facilitated by the fact that the RPi is a Linux SoC board. http://hackaday.com/2016/01/25/raspberry-pi-zero-cluster-packs-a-punch/ For...

Re: Help on SD transfer with DMA

<...> Is there a better way to accomplish this? <...> So you do not state the total number of synchronized nodes, but for the sake of argument, let's say that it is a reasonable number, maybe 12 or a baker's dozen at 13. This means each node is manipulating SD Card data, that is, there are 13 cards...

Perhaps this post will be found useful: http://stm32duino.com/viewtopic.php?t=740 As Google fully indexes this site, you can always get a fair number of hits by using the "site:stm32duino" as a suffix to your inquiry. https://www.google.com/search?q=STM32F7+site%3Astm32duino.com&oq=STM...

Re: Analog Pin Numbering

<...> IMO, No newbies, no growth in the number of advanced users. And when the older farts like you and me die off, then what? Steve. Interesting response. Honestly, the Arduino.cc forum caters to newbies and 32-bit programming using official boards, such as Due. This forum was born from one very l...

Re: Analog Pin Numbering

<...> Would it be possible to add some "official" A# style defines for the Maple? (which has shield headers) Would it be wise to add some "official" A# style defines for the BluePill? (which has a consistent pin layout) It would also mean that the new BluePill Adapter board will...

Re: ADC ENOB low value.

The "original" Maple boards were 4 layer boards, with a separate analog ground plane. As mentioned earlier, in the cheap-o boards, the analog reference is tied to Vcc which is 3.3'ish Volts. Looking at the running STM32F103 Vcc to ground with a scope, there is lots of noise present. Likely...

Re: Using STM4ARDUINO for commercial code development

Recently Texas TIVA C based MCU using their IDE which is quite similar to Arduino. Till now i doesn't used it, But when i saw the overall functionality and support side for it. Its found quite time saver and interesting. We can also put effort together to make powerful stuff like that which is able...
