Search - "microcontrollers"
Has anyone been paying attention to what Google's been up to? Seriously!
1) Fuchsia. An entire OS built from the ground up to replace Linux and run on thin microcontrollers that Linux would bog down — has GNU compilers & Dart support baked in.
2) Flutter. It's like React Native but with Dart and more components available. Super Alpha, but there's "Flutter Gallery" to see examples.
3) Escher. A GPU-renderer that coincidentally focuses on features that Material UI needs, used with Fuchsia. I can't find screenshots anywhere; unfortunately I tore down my Fuchsia box before trying this out. Be sure to tag me in a screenshot if you get this working!
4) Progressive Web Apps (aka Progress Web APKs). Chrome has an experimental feature to turn Web Apps into hybrid native apps. There's a whole set of documentation for converting and creating apps.
And enough about Google, Microsoft actually had a really cool announcement as well! (hush hush, it's really exciting for once, trust me)...
Qualcomm and Microsoft teamed up to run the full desktop version of Windows 10 on a Snapdragon 820. They go so far as to show off the latest version of x86 dekstop Photoshop with no modifications running with excellent performance. They've announced full support for the upcoming Snapdragon 835, which will be a beast compared to the 820! This is all done by virtualization and interop libraries/runtimes, similar to how Wine runs Windows apps on Linux (but much better compatibility and more runtime complete).
Lastly, (go easy guys, I know how much some of you love Apple) I keep hearing of Apple's top talent going to Tesla. I'm really looking forward to the Tesla Roof and Model 3. It's about time someone pushed for cheap lithium cells for the home (typical AGM just doesn't last) and made panels look attractive!
Tech is exciting, isn't it!?40
A Decrementing loop that compares against a zero is faster (even though insignificant on current hardwares)
than an Incrementing loop that compares against a constant/variable.
for( i = num; i != 0; i -- )
is faster than
for( i = 0; i != num; i ++ )
The difference shows up significantly on resource constrained hardwares such as 8-bit microcontrollers.

I want to touch microcontrollers again. I feel like there is always something missing when I'm coding, like I need to touch an "actual thing" or make/see things move if that makes any sense at all.19
I wrote some code using microcontrollers to control peripherals and robotic extremities using an armband called the MYO. It was a fun project I did 2 years ago in high school, I even won a couple of international awards for it!2
so i ordered free samples of microcontrollers because i didnt want to waste money... in the receipt, i saw Oct 28, 2017 and im like oh cool i guess ill receive it on that date.
today they sent me an email saying they have already shipped the package today and im like wtf why just now and i looked over the receipt again and saw:
SHIPMENT DATE: October 28, 2017
i swear to god i flippes shit because it may actually arrive in a month or two and the project has to be submitted in a month. goddamit and there is no other way! i have to buy it :(( the worst part of it is that i have another set of microcontrollers TO BE SHIPPED in January. theyre for the next project which should be submitted in January.
lesson: TIME IS FUCKING GOLD. if u want free sample, order them at least 3 months before u start the project.3
So flashing microcontrollers gets kinda annoying when you have to simultaneously fight Windows defender's urge to flag the flashing software as Trojan every 30 seconds like a 10 year old kid with ADHD that just discovered coffee.
It doesn't get easier when suddenly only one of three USB ports recognises thumb drives with the current Windows version, and only after two reboots.
Maybe I should just run it in a VM like the three remaining QA testers at Microsoft do, but on the other hand I don't really like the idea of flashing firmware from a VM. Just feels even dirtier.28
First job was coding voice alarm s Systems (1998) primarily using Delphi and programming act microcontrollers using avrco pascal and act assembler.
They were happy days2
I am writing a UI api for microcontrollers as a pet project.
I usually follow kernel.org for coding style so visited the site to see if there are any changes, these docs are so funny8
During one of our visits at Konza City, Machakos county in Kenya, my team and I encountered a big problem accessing to viable water. Most times we enquired for water, we were handed a bottle of bought water. This for a day or few days would be affordable for some, but for a lifetime of a middle income person, it will be way too much expensive. Of ten people we encountered 8 complained of a proper mechanism to access to viable water. This to us was a very demanding problem, that needed to be sorted out immediately. Majority of the people were unable to conduct income generating activities such as farming because of the nature of the kind of water and its scarcity as well.
Such a scenario demands for an immediate way to solve this problem. Various ways have been put into practice to ensure sustainability of water conservation and management. However most of them have been futile on the aspect of sustainability. As part of our research we also considered to check out of the formal mechanisms put in place to ensure proper acquisition of water, and one of them we saw was tree planting, which was not sustainable at all, also some few piped water was being transported very long distances from the destinations, this however did not solve the immediate needs of the people.We found out that the area has a large body mass of salty water which was not viable for them to conduct any constructive activity. This was hint enough to help us find a way to curb this demanding challenge. Presence of salty water was the first step of our solution.
We came up with an IOT based system to help curb this problem. Our system entails purification of the salty water through electrolysis, the device is places at an area where the body mass of water is located, it drills for a suitable depth and allow the salty water to flow into it. Various sets of tanks and valves are situated next to it, these tanks acts as to contain the salty water temporarily. A high power source is then connected to each tank, this enable the separation of Chlorine ions from Hydrogen Ions by electrolysis through electrolysis, salt is then separated and allowed to flow from the lower chamber of the tanks, allowing clean water to from to the preceding tanks, the preceding tanks contains various chemicals to remove any remaining impurities. The whole entire process is managed by the action of sensors. Water alkalinity, turbidity and ph are monitored and relayed onto a mobile phone, this then follows a predictive analysis of the data history stored then makes up a decision to increase flow of water in the valves or to decrease its flow. This being a hot prone area, we opted to maximize harnessing of power through solar power, this power availability is almost perfect to provide us with at least 440V constant supply to facilitate faster electrolysis of the salty water.
Being a drought prone area, it was key that the outlet water should be cold and comfortable for consumers to use, so we also coupled our output chamber with cooling tanks, these tanks are managed via our mobile application, the information relayed from it in terms of temperature and humidity are sent to it. This information is key in helping us produce water at optimum states, enabling us to fully manage supply and input of the water from the water bodies.
By the use of natural language processing, we are able to automatically control flow and feeing of the valves to and fro using Voice, one could say “The output water is too hot”, and the system would respond by increasing the speed of the fans and making the tanks provide very cold water. Additional to this system, we have prepared short video tutorials and documents enlighting people on how to conserve water and maintain the optimum state of the green economy.
IBM/OPEN SOURCE TECHNOLOGIES
For a start, we have implemented our project using esp8266 microcontrollers, sensors, transducers and low payload containers to demonstrate our project. Previously we have used Google’s firebase cloud platform to ensure realtimeness of data to-and-fro relay to the mobile. This has proven workable for most cases, whether on a small scale or large scale, however we meet challenges such as change in the fingerprint keys that renders our device not workable, we intend to overcome this problem by moving to IBM bluemix platform.
We use C++ Programming language for our microcontrollers and sensor communication, in some cases we use Python programming language to process neuro-networks for our microcontrollers.
Any feedback conserning this project please?8
-Machine Learning (especially Reinforcement Learning & GANs)
Of course I want to finish the projects I'm currently working on and maybe start a YouTube channel about my projects.
Yes I know, it's quite a lot to do, but I don't know if I will ever have the chance to do all that things in my free time again.
Now that I have your attention. My problem is with "IAR embedded workbench", not so much with windows but I'll get to that.
I've used that IDE for a few years.. 2 years ago. Since then I apparently forgot how to even create a project from scratch with adding all the necessary libraries and all that.
My initial deal with a client was to give them a solution using whatever tools I deem necessary. As I recently moved to linux and IAR is not available for that os.. and I also enjoyed working with CLion and PyCharm which Are available I decide to use CLion to write my C project.
A problem was that to compile code for microcontrollers I need tools unsupported by CLion.. oh well. I can do all the compilation and uploading of the code through terminal .. so I make a bash script that does it all. Super convenient. Development is going well and all.. until they ask me for the project.
I sent them the project so that they can see my progress. They can't do shit with what I gave them because they don't even have make on their machines let alone the compiler. All they have is IAR. But the guy that wants to see the code is not really a programmer.. he is a hardware specialist so I can't expect him to do anything more than use what he knows. He doesn't need or want to learn more right now.
So I go to windows and start porting my code to an IAR project and 2 days later I am still stuck with it. FUCK. Not only was the installation process horrible but the tools I wanted to install additionally did not work as promised either.
I know it took me about 2 days to setup all I needed on linux but I was enjoying it every step of the way. While this garbage is frustrating me so much. The fact that I used to do it before adds to the pain.
I am this close to telling them to just look at my code in notepad and I can setup a vm for them in which they can compile it if they really really need to.
If they just told me from the very start that they want me to work with IAR that would have been fine. I would have never seen the easier way and would have gladly figure it out then. Not now.1
Right now i want to put together a system to automatically water/warm/whatever my chilli peppers, but on the long run i want to embed some microcontrollers into my body.4
I'm part of a robotics team in my highschool. We work on autonomous robots, which are driven with microcontrollers like the Arduino and "bare" Atmel chips.
Last year we were using a protocol called CAN. CAN is a bus which runs at 1Mbps and it is quite easy to connect devices together. (It's a bus ofc it is). BUT... it needs a terminator at the end, mostly 120 ohm.
Every year we are on a deadline and something broke on our current board and we needed to solder up a new one, but we couldn't find the 120 ohm terminator... ANYWHERE!
At end after searching for it in the workshop for 4h straight (12am- 4am) we finally found it, and soldered up the new board and guess what... it wasn't what we thought, the code was the problem.
After realizing the problem my teammate and I, in silence just stood up, packed our things and went home. Argh!2
I've been noticing that without any specialization development can become repetitive, as in, a bunch of fancy ways of doing the same CURD operations.
Something that just calls me is low level development, wether it is embedded development (microcontrollers and such) or Linux Kernel and device drivers. I've been polishing my C skills for a while now and started to look into kernel development and uff, is it overwhelming!
I just wanted to see if some of you guys are or had experience in system development and how you got there. Thx!3
This may be a dumb question, but are there any benefits in learning c instead of going straight to c++ for microcontrollers? I'm in my first ee semester and wondered, because we are learning c and java (next semester), but not c++2
Today I have created a server application on Python Tornado which can forward TCP Packets directly to HTTP request queue without any intermediate caching.
Our remote IOT devices (microcontrollers with sensors attached) send sensor reading over TCP Socket to our server and all the connected web applications can show the data instantly using long polling and the above mentioned technique.1
First microcontrollers, then university, now self-taught, with plenty of Googling all through.
Mainly working with VBA and PHP at the moment
I would really like to get into electrical engineering and microcontrollers, but I dont have any (real) experience with circuits and stuff.
Can anyone recommend some books, starter kits, good microcontrollers or youtube channels?😄3
I wanted to know a few suggestions of cheap/easy microcontrollers for you to learn a bit of assembly.
Nothing fancy though, I just want to experiment with these things.14
Working with microcontrollers is like another level of frustration.
Beside the code not working you are on another level, which is the hardware not working...
Once spent 6 hours searching for a bug and in the end the "bug" was swapped cables for communication.2
Started with VB.Net, moved to websites with WordPress. Shortly after I wanted more control over the output and started using CodeIgniter, then FuelPHP.
In the meantime, I learned Java to try making Android apps (and quickly gave up because both regular Java and Android APIs are a mess).
A robotics club started in school which made me go back to BASIC for programming Picaxe microcontrollers, then C++ for Arduinos.
Currently, I focus on progressive web apps and sometimes native libraries/programs with C++ when performance is critical.
All the learning was mostly done on YouTube (thenewboston channel)
