Not exactly a micro, but who cares

>>62328064
What do I need if I want to remotely turn my PC on and after an interval press F2 through USB HID?

I have a VoCore
Took me 6 months to get it from kickstarter
Now I don't have a good use for it, but it has built in wifi and uses less than 0.5w. Not exactly a microcontroller but a small MIPS cpu and 64mb ddr2.

>put in in a wall socket hosting some random website
super small, what are some cool ideas

>>62328064
stm32f103 is bretty good, i buy them by the dozen, so cheap and they have some nice features for a medium density chip, i work on a similar density pic at work and it's crippled, only 1 uart and no dma, 2 (two) interrupt vectors.. drives me nuts

>>62328064
How do I into external DDR4 memory and how do I into SATA 6gbits, ethernet and PCIe?

Maybe use it to download shit from the internet
I download 360p anime (shit internet ~1Mbps) all the time, but i feel bad to leave my desktop or laptop on to do something so trivial. So i made a script to have a spare smartphone (debian chroot on it actually) to automatically rip the direct download links and download them.
Tbh even a smartphone is still way too overpowered for downloading a couple of files. That VoCore thing sounds like the ideal solution desu

point cloud slam on a fpga
shits terrible to debug and test
xilinx get your shit together

>>62329082
nothing could be worse than altera tho

>>62329092
no experience with altera
i dont have complaints with the xilinx hardware it interfaces well with my lidar, its their vivado ide thats shit

>>62329145
neato, just saw the seeed lidar got released, i'll impulse buy it one day im sure

>>62328064
waiting on some pic self assembly kits in the mail, got an st link in the mail the other day and I plan on putting gnuk on a NUCLEO-F103RB when I have some time, other than that not much else at the minute

>>62328105
you want something that can act like a usb host, some pics can do this and teensy boards are quite cheap

Building a Pager like thing that fetches messages from monitoring and alerts if something new came in

i hate these things, every display i have bought since this has an spi interface

>>62329326
eh, I have enough pins to spare currently. I would've need to buy an SPI adapter and it's just not worth it

>>62328064
Not working with µC's atm, but doing bare metal stuff with my raspberry.
Yesterday finished a led blink tutorial and now gotta work my way up to actually use C, build a framebuffer and do some shit.
Cool thing would be a forth interpreter, but I don't know if I will ever achieve this

forget webm, because I am dumb. webm related.

>>62329344
p sure you wouldnt need an adapter, if avr doesnt have hardware spi there will be a library that just bitbangs it

>canon

>>62329382
>>62329370
Baremetal, as in pure ARM assembly?

>>62329405
AVR is programmed using SPI, so it definitely has at least one.

>>62329435
Yes

>>62329326
At this point the only reason why they're still using the old interface it's to sell you I2C/SPI adapters

>>62329516
Are you dumb? Why would you add the bloat of i2c or spi if it is not needed everywhere?

>>62329530
I would take my software bloat over your a-hundred-ports-needed hardware bloat any time

>>62329566
>what's KISS principle
Adding bloat where it isnt needed is just plain retarded and everything that went wrong in the past few years.
Go back to school or kys.

>>62329405
But an adapter interfacing the LCD from SPI

>>62329566
When you still have free pins, use them. ROM space is limited

Anyone here use Ti C2000 MCUs?

o i got u, yeah thats what im saying, i'm happy to pay an extra couple of bucks for the convenience of only needing to connect 4 wires instead of 8.. or if we are talking lcd then pic related, 2 lcd touch screens i have on hand, 4 pins or 40 pins. my time is worth quite a bit, im happy to pay for convenience

>>62330305
But you still need one pin for each spi device, right? For slave select iirc

>>62328358
Too bad they dont make it cheaper and actually sell the fucking thing

>>62328105
You can do that with wake-on-lan and ssh, mate.

>>62333203
Nah m8 I can't. That's exactly why I need something like this in the first place.

>>62328358
Sneak it into some library or something, stick it somewhere no one will ever find it, and run an openvpn server on it. Bam, a (admittedly shitty) VPN for cheap

>>62328358
The Raspberry Pi Zero has video output via HDMI, DPI, MIPI DSI (proprietary shite) and analogue (non HW accelerated). What video output options does the vocore have?

Doing some stuff with a ESP8266 and spi e-paper module. Going to display different messages posted to the device through mqtt.
