better this than makishit and RX 480 shilling have a bump otherwise might give you more luck
Ethan Miller
This, have another bump.
Have couple arduinos and raspberry pis. Considering buying some ti launchpads to get more serious.
Any recommendations?
Daniel Gutierrez
MSP430 is good because you can take the chip out and pop it on a breadboard, or any other circuit you make. 16-bit.
The 432 is a 32-bit, and a little more powerful, however, i heard in the last thread that you can't buy the chip separately, it's a SMD only right now (and it's been out for like a year)
Christopher Richardson
Hi there. I have 5 Raspberry Pis, I often use it for playing games with emulators or movie/YouTube watching. I have noticed that the Raspberry Pi 3 tends to overheat quite frequently, especially when WiFi is involved. I have applied a heatsink using thermal epoxy instead of the sticky thermal tape that was under it, and now it's way more responsive. I believe it's because of the thermal conductivity (10 to 20 times better). What's your opinion?
Wyatt Rivera
yeah, thermal paste is the only way to go, and when heat can radiate, electronics work better.
however, arduino is more of a SBC, not a micro controller. /SBC/ ->
Anthony Ramirez
Thanks. Ordered a 432 since I wanted 32-bit with WiFi. I'll see how it goes ;)
Jackson Ramirez
>>Texas Instruments Launchpad >>Arduino >>beagleboard What is this shit? Where are pure AVR, PIC, Z80, 6510 chips? Hmm? :-) Anyway just got an FPGA. I also want to get a rpi3, install win10 on it. Program Cortana and make it into Jarvis or some cool movie tier shit. Get the fuck back to or to your shitty ass consumerism thread.
Michael Myers
Why do my atmegas break? Ordered 2 8535 and one of them just didnt work, also had an old 88 lying around that I'd never used, also broken.
Blake King
Anyway got another atmega88 that works, I've programmed an audio delay on it with pots for feedback and delay time control. It's super lofi and shitty (using 8-bit pwm for audio output lmao) but it's fun. Gonna solder it in a case now.
Luis Hughes
>still no cortex a72 board on sale fuck my shit up senpai anyone writing an OS for ARM here? I am gonna make an exokernel :3
Nicholas Rodriguez
Static electricity? How do you store them? Also, how do you use them?
Do you put bypass capacitors around the atmega? I had problems with it seemingly not working with longish programming cables without proper bypass caps.
Are you sure that you always keep them within their absolute maximum ratings? Don't short outputs to ground/vcc, etc...
I don't know your background, so sorry if my questions are too simple.
Christian Perez
No you're right, I'm probably just messing up some simple stuff. Also my laptop is kinda broken and leaks current. I'll try bypass caps next time.
Dylan Howard
this poster has no idea what he's talking about
>hurr i buy electronics for the feelings they give me because then i can feel like i am a man from a comic book who is computers
William Morgan
Nope, it's challenge. I can also connect stuff using wireless and have Cortana tell me shit. It's also not bad to have a little fun sometimes.
Regarding "pure" chips: I learn a lot more that way, boards are excellent for prototyping though depending on your needs.
If you don't get this, then we don't have anything to talk about, I like doing cool stuff, you don't. Your problem. Anyway, nice bait.

it doesn't count unless your mcu has DMA

dude, you lost. you're wrong. you dont know what you're talking about, at fuckin all.
we are talking about chips and shit in here. this is where we talk that chip talk. didn't you hear the intro music?
Kevin Reyes
>mfw I fell for the intel edison meme
Nathan Nelson
you cant even buy that shit now. i tried to buy the one with the breakout board, and it was unavailable.
you cannot understand us because you are too soft.
Nathan Richardson
I'm planning to get an Odroid-XU4 for my 1st NAS. I would get microsd separately for the OS.
Am I fucking it up?
Brody Sanchez
>Am I fucking it up? Yes, you're posting in the wrong thread.
Matthew Mitchell
I had a sensor kit like that, looked pretty fun but never got around to it.
Michael Rivera
Why? I though I could learn more about Odroid, Raspberry, Orange Pi etc here.
Andrew Jones
There's already thread for SBCs up.
Jack Bell
What are the C concepts one should master to have a shot at a good embedded programming job?
Hudson Price
fizz buzz
Easton Bell
...
Nathan Harris
Reading datasheets.
Isaac Jones
I mean, would it be expected that I know C/Posix multithreading by heart? Those sort of concepts
Isaac Watson
Pointers, bitmasks, macros, casting. Knowing how your mcu works, memory layouts, etc. is also needed.
You will run into a few C "extensions" while programming embedded which differ from platform to platform, compiler to compiler. Specific to programming your chosen cpu. You will also need at least a moderate understanding of assembly, if you want to really go deep and know what you're doing.
TL;DR Get really good with C. Learn basic assembly; enough to know how the architecture of your mcu works.
Oliver Peterson
Err... what kind of embedded programming do you want to do? 1. 8 bit mcus, like avr atmega328? 2. ARM Cortex-M3 32 bit mcus? 3. Something like an ARM cpu on par with a raspberry pi?
First one won't have an os, you will be programming bare metal. Second on might have some tiny real-time os. You will be programming bare metal too with a few added benefits. Third one will have, most likely, some linux, ,maybe one with a real-time kernel patch. This is probably where the multi-threading will be most useful. In the two other cases, tasks will be very different to your average PC-tier multi-threading.
Xavier Williams
>People using my picture for /embedded/ Well, I'm mindfucked.
Okay.
Wyatt Gomez
>Arduino is an SBC >Not a microcontroller
Caleb Sullivan
Better the Edison meme than the Galileo meme.
Shit I was on a project where our whole team were GIFTED Galileos (not even "We'll need these back" units either) just to try and convince us to use them.
That piece of shit is still collecting dust in my closet.
Nathan Parker
An arduino is a SBC with a microcontroller at its core. How is this hard to understand?
William Adams
If you widen the definition of SBC to include "any singular pcb what can do compute" then yes, you'd be right, but then it'd just be synonymous with "dev board" and be a useless term.
On the other hand, if you'd like to propose a new nomenclature that separates microcontroller dev boards like Arduino, Nucleo, and Launchpad, from Tiny Embedded Linux Boards like Beagle, Pi, and ODROID, I'm sure we'll all ears.
Evan Ross
>1. 8 bit mcus, like avr atmega328? [...] won't have an (rt)os >2. ARM Cortex-M3 32 bit mcus? [...] might have some tiny rtos
I'm thinking of going /sensor/ soon, really want to build a weather station that I can access over http, with inside and outside sensors
Ian Brooks
I don't use a os on small mcus. I know a lot of others who don't. Most of the time it comes into play with "larger" mcus.
You're right though, it's possible and they ported it. I think most of the time on small mcus you do bare metal programming though.
Anyway did they port anything other than the scheduler?
Easton Davis
Not entirely sure about how much of freertos is running on the 328p. I just was bored and wanted to point out it has and can be done.
Lucas Turner
rpi3 only installs windows 10iot, i'd get your facts straight before you spend any money dickhead.
Bentley Allen
As far as I know IoT has Cortana.
Tyler Morris
Win10IOT doesn't even have a start button or a taskbar, I wouldn't think it has cortana. I know it doesn't have it out of the box.
Jayden Cox
Hi friends, I should probably just fuck off to DIY but short blog incoming: Starting school later in life than I planned to and I'm majoring in computer science with hopes of going into sysadmin. Anyway, this has motivated me to do cool shit. I'm thinking about buying a raspberry pi or some other board, usb wifi adapter with removable antenna, heatsinks, fan, switch, and lastly an LCD. I plan on either getting a 7 inch and using it to manage the router directly, or just managing via ssh and using the display for cool things like network stats or something. Figured I could also use this as an excuse to play with some CAD software for the first time in my life to design a case for this thing. It should only be like $150 tops. Am I being retarded? Should I just buy a decent openwrt router? A big reason for this is also the ability to tether my phone to the router with easytether/openwrt since it's LTE serves as my main line.
Parker Garcia
Googling shows that it has speech api. Recognition included. Cortana can go and fuck herself though. youtube.com/watch?v=GiDvBhfNnjU
Eli Long
Currently """""reverse engineering""""" the key matrix of an electric typewriter. I'll remove the keyboard, put in an Arduino and make it possible to remotely send stuff to type. My own ghetto Teletype if you will. Does anyone have an Idea how I could avoid soldering a whole new "virtual" key matrix?
Matthew Harris
please post link
Tyler Cox
Are they SPI or 1-Wire sensors? Or just plain and simple ones with analog output?
Brayden Martinez
not him, but look around on aliexpress tons of very cheap modules there
Brayden Barnes
I'm waiting for some final prototype boards for a project, a DAC for laser projectors based on the ATSAM4S2B mcu. If it works I'll order a hundred of them to sell. Pic related, a render of the board without enclosure
Nicholas Davis
Wat Arduino is an ATMel microcontroller with some periphery. Very far from a SBC
Jordan Jenkins
Bumping this thread because its actually Sup Forums related, unlike 90% of the other threads.
Nicholas Hill
Neat, I've always wanted to do that too. But it seems soldering to the multiplexer is your only option, unless it uses some serial thing right after that which would be less wires, but more work reverse engineering it probably.
Noah Powell
Yeah, maybe I'll check the chips that are on the mainboard, possibly I can find out what they do.
Jace King
Are there any dev boards/etc for 64 pin PIC's that don't require soldering?
Luis Peterson
Not sure if that helps you but the Arduino Mega has tons of pins.
William Ross
Nah, did some stuff with a 64 pin PIC MC a while back and much preferred the direct low level C stuff that came with it vs the Arduino's. Wanted to try out a PIC + some other shit again but my current soldering iron is straight garbage.
Blake Nelson
How hard would an embedded systems programming job be? I got approached for one but I was like nahh. I'm betting pretty hard.
Jordan Morris
Terry Davis funnily enough was an embedded systems programmer for ticketmaster. His language choice nowadays is Holy C, which as you can guess is inspired by C. I would think that embedded programming is focused on efficiency, although I don't know for sure.
Jaxon Long
Can you take another picture for us?
Julian Long
Generally you dont have a shit ton of resources to fuck around with programming embedded, so I would agree with you on needing it to be efficient
Aaron Diaz
I'm coding apps for the Pebble.
IoT is very beautiful. I see why its good now. API's, api's everywhere.

Connor Hernandez
wtf u do? u can generate ur letter structure's source code with regex search and replace...
Joseph Green
Can you rephrase that in real english please?
Ryder Lewis
Because shitposting takes way less effort than actually discussing something of substance, welcome to Sup Forums. Nice project, by the way.
Isaiah Brooks
what parts should I buy for this piece of shit.
Brayden Lopez
get some rgb leds, they're always fun and very cheap
can also give you an excuse to play around with charlieplexing or shift registers to drive more
Parker Turner
gon try dis in mine, I have those kludgy little heatsinks too
Eli Walker
trash can
Ryan Gomez
I don't need to buy a trashcan.
Lincoln Cox
what's happening? Sup Forums has some very good threads today...
Jason Walker
Thermal paste is only as good as its heat dissipation rating. Same goes for thermal tape. I have some thermal tape right now that's better than your standard arctic silver paste and it's going to eventually go into a small fanless wearable computer. The big draw of the thermal tape to me was being able to use it as a means of protecting the electronics from electrical shock, which means I can use the case itself as a heatsink.
thermal tape just gets a bad wrap because it's typically used by companies doing what I'm gonna do, but they cut corners on quality, and buy the cheap shit which is very low on the conductivity side.
Grayson Myers
Maybe the Sup Forumsirgins are all in school and the actual Sup Forumsentoomen have a day off
Isaac Adams
>[any] thermal tape >better than arctic silver citation needed
Isaiah Garcia
What's the best (read: cheapest) way to get into FPGAs with networking? I've done audio stuff with the Altera DE-2 SoC, but I would like something where I can e.g. interface with PHY chips (RGMII) or SFP transceivers. Implementing switching and routing harware etc. Most boards only have one network port, and I've seen some that already have higher level controllers. I just want to go into the basics.
Ryder Turner
I did specifically say your standard arctic silver paste, not knocking the product, but they do sell varying degrees of thermal paste. their high end stuff probably wins out, but I didn't buy the highest tier of tape, either. I went with the tape that dissipates ever so slightly higher than the aluminum case that it's connected to (it'd be a waste of money otherwise).
Pic related is what I got, which is better than arctic silver's Alumina paste by 2W/(m·K). The pad is also made by arctic silver.
Oliver Price
I think you're forgetting about your units here. these pads are 1.5mm, where grease is commonly applied in 0.1mm thickness. The 'm' in your rated thermal conductivity equation there stands for meters.
Julian Anderson
Ah, good to know user. Sorry for my misinformation then. I was more focused on the units total output when I spoke out.
Nicholas Hall

Did they ever get around to fixing the Pic Kit 3 after Dave Jones did that rant and Microchip did that one response video?
Grayson Williams
What cortex-m7 eval board should I buy? Atmel or ST. I'm going off of what's available on digikey Canada.
I have limited NEET money so I'm leaning towards ST because the nucleo boards are the cheapest.
Jaxson Watson
What would be the best way to make a bluetooth receiver for a sound system I'm making from an old record player? I've got the amp and speakers set up with a 3.5mm jack soldered in place of the input from the needle. Now I'm keen to throw in a raspberry pi zero (or something) with a bluetooth module and stream music to it from a laptop.
How should I go about doing this? Is the raspberry pi zero suitable for this?
Charles Long
If you have limited money, don't bother with an M7.
If you're just now learning to get into embedded, you won't be able to get even half the advantage of using a CM7 for prototyping.
Grab an F4 Discovery. $15 USD on digikey, and has everything you could want. out of a dev platform.
Now, assuming you've read the rest of my post, if you're still dead set on a CM7, then the big advantage I can state is that more people are going to be familiar with ST ARM chips rather than Atmel ARM's, and the ST Nucleo is supported on mbed.
Easton Gutierrez
