Works great, thanks!

NIW

I'm pretty new, I just need the pi to go straight to the command line after booting, so i don't have to type in the username and password.

NIW

I was wondering how to disable the login on the raspberry pi, but all the tutorials I found were super outdated. Are there any ones for the latest version of raspbian lite?

NIW

That question doesn't make sense. I'll explain, I had python programs I wrote on my raspberry pi. I backed them up to my PC so that if I burned a new image of raspbian onto the card, I would still have the programs. Since last time I tried to mount to a usb device I broke my pi, I wanted to know if...

If you build a fresh copy of Raspbian on a fresh SDCard you get a full system. Clearly what you're looking at it the poxy NOOBS recovery system, which has the usability of an ashtray on a motorbike. lol thanks, Is there a way I can get the python programs I wrote on to the pi without using a usb st...

Boot the rescue system. Open LXTerminal (or press [CTRL]+[ALT]+[F2] and login with pi/raspberry). sudo -s mount /dev/sda2 /mnt mount /dev/sda2 /mnt/boot cd /mnt/boot nano config.txt cd /etc nano rc.local cd / umount /mnt/boot umount /mnt exit # when done The rescue system only boots in emergency mo...

NIW

How is that any different to building a Raspbian "Rescue" System? I tried using the rescue system, but i somehow made it so that the pi couldn't access the command line. I want to reformat the drives and upload my programs, but idk if you can access the boot directory (has cmdline.txt) fr...

NIW

Also, could I access the recovery directory from the command line.

NIW

More problems, I tried to acces the usb drive folowing this tutorial https://www.instructables.com/id/Mounting-a-USB-Thumb-Drive-with-the-Raspberry-Pi/ once i restart, it says I can not access the console and the root account is locked. What is going on? :? I think I will just reformat the drives, b...

NIW

Is there any linux file editors I can get for windows? I have disk internals linux reader, but you can only back up files, not edit them.

NIW

Well, I tried it, it booted in emergency mode, but it still ran the program and I still couldn't get out with Ctrl+c.

NIW

Or try the non-Noobs method from viewtopic.php?p=1333129#p1333130
Ignore the title, the method is the same

Once I do this, how do I find rc.local? I also don't have notepad++, but I can edit the file with pspad.

NIW

Well, I screwed up. I was doing some testing for the ROV I am building, and I put sudo /home/pi/MainControl.py in /etc/rc.local to cause the program to run on startup. I did not code a way to end the program, and the Pi will not accept keyboard inputs while the program is running, so I can't CTRL-C ...

I am going to be using this ( https://www.sparkfun.com/products/12009 ) bi-directional logic level converter to communicate with Raspberry Pi 3.3v TTL serial and a 5v TTL serial device. Would this logic level converter cause any kind of delay? I am using this for motor controll so I need the speed t...

Your mosquitto broker @ 10.1.2.80 isn't working.

Thanks for the help.

NIW

mosquitto_sub -t '#' -v -h 10.1.2.80 & mosquitto_pub -h 10.1.2.80 -t 'HELLO/WORLD' -m "$(date)" Then run your publisher program. I ran the first line of code on the subscribing Pi, it said [1] 945 I ran the second and it said after a while Error: Connection timed out I ran publishing ...

So after getting MQTT to work over an ethernet cable ( https://www.raspberrypi.org/forums/viewtopic.php?f=32&t=192632 ) I preceded to work on other aspects of my remote controlled submarine, but the Pis will not communicate. I am running this code, #!/usr/bin/python # -*- coding: utf-8 -*- # Cop...

If you installed the full version, not light, have you started the GUI desktop and checked the status of the WiFi? Make sure it is "On" and connected to your network. Sometime the RPF servers are overwhelmed and you may need to try a again at a later time. I have light, I installed the up...

I was trying to update my raspberry pi (sudo apt-get update), but when I hit enter it said: 0% [Connecting to mirrordirector.raspbian.org (93.93.128.193)] [Connecting to archive.raspberrypi.org (93.93.130.39)] after a few minutes it did this: Err:1 http://mirrordirector.raspbian.org/raspbian.org/ras...

I am going to use the adafruit servo hat for my Pi, and on the website they say that it uses only two gpio pins, how would I use the other pins it does not use?

NIW

I am using the Adafruit Servo Hat and a BRUSHED ESC no problems. Did you leave the positive (Red) wire on the connection, because I was wondering if the esc would fry it if I did. I heard that here, http://www.instructables.com/id/Driving-an-ESCBrushless-Motor-Using-Raspberry-Pi/ I dont know if it ...

I have a Blue Roboics Standard ESC, ( https://www.bluerobotics.com/store/thrusters/besc30-r2/ ) and I have seen the Adafruit Servo control hat ( https://www.adafruit.com/product/2327 ) and I was wondering, They both use PWM, could I use the Servo hat to control the ESC? Also would it fry the Hat? If...

NIW

I tested It and....

IT WORKED

Thank you everyone who helped me accomplish this.

This is going to help me build my ROV ( RC sub) so much.

NIW

I did

Code: Select all

sudo killall dnsmasq

and then ran

Code: Select all

sudo dnsmasq

and nothing happened. It just went to a new command line.

Did it work?

NIW

Did you do the single Pi test as I suggested?

Yes and It worked just fine.
I have gotten the pi's to communicate over a wireless network, but getting them to communicate over the cat5 cable has not worked yet.
