i want to make USART communication serial between two microcontroller ATmega8535. i am using 2 minimum system, 3 LED as ouput, uncommon keypad as input on each minimum system. i want to make it when i press either keypad the LED turn on according to number on the button pressed. i dont know whats wrong with my program. All the LED keep turn on and not respond to the keypad.
but when i only use 1 minimum system, 1 keypad, and 3 LED, the LED is working as i want it. here's the program:
.include "m8535def.inc"
.org 0x00
rjmp main
main: ldi r16,low(RAMEND)
out SPL,r16
ldi r16,high(RAMEND)
out SPH,r16
ldi r17,0xff
ldi r19,0xfe
ldi r20,0xfc
ldi r21,0xf8
ldi r22,0x00
ldi r23,0x06
ldi r16,0xff
out ddra,r16
ldi r16,0xf1
out ddrc,r16
rcall USART_init
load: sbis UCSRA, RXC
rjmp led

You seriously thought /g/ can help you with actual technology related problems?
Well then you'd better act now; this is a limited time offer.

>AMD
wasn't lenovo the company caught with some of their chinese botnet stuff in their laptops? WHY THE FUCK IS THIS THE /G/ CHOICE OF LAPTOP BRAND?
Why don't you write C & C++ /g/?*ptr = (((data->header) & 0xFF00) >> 8); ptr++;
C++ got to be the most complex and obscure language in the world.

It's designed to do that, retard.
Does /g/ know who this man is?

Obviously. His name is Chapter 4-115.

How does it make you feel to know that no one runs anything but Windows on enterprise servers besides a few cringey and nerdy amateurs?

What it's reliable easy to setup and doesn't break for no God damn reason.
Those nerdy amateurs get fired fast.

ofc a product fails if it has no games, steam library is filled with linux support indie games that only require a Dpad and some buttons.

Morning /g/, I want to create a text document that has text in 8 equal sections like pic related w/o the black border. How do I do it please?

gentoo does it out of the box. install it.
>>53861072
Funny. Right, sorry, I should've shown that I was aware of that meme and said "Morning /g/entoomen". Forgive me. Now, if you don't mind, help me.

Why did you go with GNOME over KDE?
Time for some Dark Souls II.
Anyone else love xp, skip vista, and still use win 7 because 8 and 10 are shit?
>>53860828
>8 and 10 are shit
I want memecucks who just spout parrot memes and don't know shit about functionallity and workflow to leave my board, please just go back to >>>/v/ or something
>>53860828
XP is okay. 7 is better.
But i don't love Windows, my love is all for 'my' OS which i formed from ground up. You guessed it, it's Linux.
>>53860828
8.1 is not shit. 7 and 10 are shit.
I was wondering, because this retard
(https://www.youtube.com/watch?v=OfscbJldcAI&t=1051s)
spent 10k on his setup, and he's got a dual xeon system, but is that any better than say, a single I7? if it is, are the advantages negligible or?
thanks in advance, famalams

Max clock speed is only 3.7GHz but the cache is huge. I doubt it is worthwhile at all for /v/.

Hey guys I am trying to build a gayman PC. My laptop's 650M is already showing its age so... yeah.
I was looking at LI but the great PC only has one option for the 960.
The ZOTAC GeForce GTX 960 2G
Meanwhile other sites have more options like
MSI - NVIDIA GeForce GTX 960 2GB GDDR5 PCI Express 3.0 Graphics Card - Black
eVGA - NVIDIA GeForce GTX 960 4GB GDDR5 PCI Express 3.0 Graphics Card - Black
Is there any difference? Will it affect the unit if I don't go what LI says?
Also, the Great PC has AMD processors only. How do I know if I can use an intel processor? Or can I use one at all?
Why nvidia? As stated my laptop has a 650M and since 2011 it's been performing great. I am happy with their products and I'd like to continue doing so. This has nothing to do with meme cards and shit. I don't care for that.
However if you guys have a reason to get ATI's I am open to suggestion.
And last one question, sorry. Are there any compact cases? I don't want a monster hueg tower.
anyone?
>>53860650
1. Don't buy a GPU now. In a few months both AMD and Nvidia will release their new line-up which is supposed to be a lot better, though a lot of negative news is being released every day.
2. Don't get the 960 4gb. It has a 128bit bus that basically trottles over 2gb of vram. You can look up benchmarks and see how the 4gb model has like 1 fps more than the 2gb model.
>>53860650
>However if you guys have a reason to get ATI's I am open to suggestion.
Now you're just asking for shills to post and start some brandwar.
> Are there any compact cases? I don't want a monster hueg tower.
More than ever. There's mini-ITX, which are really small and need special parts usually.
And there is micro-ATX, which fits more standard parts, and has a wider and cheaper selection of motherboards. They're bigger tho
Ok /g/ need you guys to give me a clear cut answer what you prefer and why. I own a 4k 60 hz monitor and regret it every day after trying 2k 144 hz. My friend who is autistic says 4k 60 is better. He thinks that 2k 144 hz is pointless.... Sigh
Tldr I own 4k 60 hz and tried 2k 144hz and it's 10 times better than 60 and so much more fluid. Also Gsync for either pick or free sync.
As stutter is removed at higher fps with variable refresh rate
60hz is way too slow, 100hz is bare minimum for fast action gameplay. Hell, even in windows there' a night and day difference.
>>53860642
Op here and this is not a gsync vs free sync thread keep that shit out of here from debate.
>inb4 paying for premium for gsync
Just talking about hz here
2k 144hz
higher hz>higher res
IMO
