Re: Usb

Dit gaat (spijtig genoeg) niet.
De de USB poorten zijn 2.0 en deze gaan samen met de ehternet connectie over één usb 2.0 poort naar de processor. ;)
Je kan wel een 3.0 schijf aansluiten, maar dan zal de snelheid theoretisch maximaal 480Mb/sec zijn, dus 60MB/sec.

Re: Sd card

Dit zou moeten gaan. Hier zijn er nog personen die zeggen dat het werkt. ;)
Ik denk alleen dat het beter is om een 'kleine' sd kaart te gebruiken voor het OS en dan een USB stick/harde schijf voor je data.

Re: ttyAMA0 Missing

I had to reinstall my Pi because the SD card went bad so I used the lasted version: jessie from 5/27. I need to use the serial port for my code so I used raspi-config to disable boot from using the port, just like I've always done. Problem is that the /dev/ttyAMA0 is missing. I also disabled the se...

Re: Two Raspberrys on one Arduino

You can connect the arduino via USB to one pi and use a FTDI usb cable for the other pi. You should connect the FTDI cable to anonther serial port on the arduino, so if you have a mega, use TX1 RX1. If you have another arduino, use software serial. ;)

Re: Create high frequency digital data signal over gpio

If you are still interested in this endeavor, you can google Arduino VGA. You can create VGA signals using Arduino. The display area may be small but at least that gives you an idea how to do it. Yeah, but an arduino is real time. The raspberry pi running an OS is not real time, the OS will interru...

Re: rasp Pi as a controller

You can also use an I²C GPIO expander. They normaly give you 8 extra IO's and you can connect up to 128 on the bus. So a 1000 io's should be enough I think. ;)

Re: Using a PC and an Android Tablet

With a tablet, you can install an ssh app (there are many, out there) and connect over wifi/ethernet. ;)
With VNC, you could use the desktop on your tablet, but you'll have to install it on the raspberry pi.

Re: Pi 3 in an old laptop. Is this madness?

I got the touchpad and keyboard of an old macbook pro working via USB. Maybe this is the same for your laptops.
For the screen, you'll probably need some kind of driver board.

Re: Code with two grounds

On the assumption that those are push to make buttons, then it should work. However there is no pull-up resistors, so either they need fitting, or use the internal ones. Texy No, it won't cause the pi can't determine the difference between left down and up right. Instead of connecting GND, you can ...

Re: Code with two grounds

What you are trying to do is make a button matrix.
For this to work, you'll need at least 4 GPIO pins for 4 buttons.

Re: Is this asking too much of a Pi?

I think every thing is possible, but you'll need some pretty big solar panel. ;)
It's probably better to run it of mains power (if possible).
For connecting 2 camera's, at least one will have to be a USb camera. :)

A foolish question from the uneducated - what will happen if you connect a power source to both ports at the same time? Nothing fancy on the Pi side :) . But this will only work if you connect the same power supply to both ports. If it's not the same power supply, you could damage the supply's. (Th...

Re: Hook-up 7" touch screed

These are to connect the I²C from the display to the pi if you have an older pi.
You do have to connect the 5V and GND wire from the display to pin 2 and 6 of the raspberry pi.

Probably a reason to buy a new Pi. :)
