LibreELEC/Kodi 04/18 - Can CEC be disabled?

Hi All, Just set up Pi 3 and it is connected as an input to ONKYO receiver through to Samsung panel. For some reason the Samsung switches to a different input (away from the connection to the receiver resulting in a no signal screen) at random times and must be reset to the correct input (at which t...

Re: Running python script on startup

Here is the contents of tempbus.py, it was running 1Wire devices straight from RPi pins but due to wiring topography the system was unstable if I had more than about half connected. Now have i2c 8 x 1Wire bus chip and so far hooked 12 sensors up to 1 bus and it's rock solid. So I commented out some ...

Re: Running python script on startup

When I saw the thread title I thought I couldn't miss an opportunity for a better way to auto start a python script at boot. I have adapted Dougie's code to suit my situation, running a python script to get temperatures from i2c bus - 1Wire devices and log to data base. The script is named tempbus.p...

 The best thing is to use a Real Time Clock, if you need more accurate time keeping.
The RPi's have network access most of the time, it is just in the event of power outage when they reboot faster than the network comes back up so I'll see if there is a solution in sync frequency.

Re: Managing System Time on RPI

Take a look at the man page for timedatectl with a man timedatectl command. As soon as the network reconnects your RPi should sync to an internet time server. You can add a RTC board if you need the time to be set when the network isn't available. https://cdn-learn.adafruit.com/downloads/pdf/adding...

Managing System Time on RPI

Hi All I haven't messed with the system time on my RPi's as they have access to net and sychronise without me having done anything. It's all fine if the network is up when the RPi's boot. However, in the event of a power failure and reinstatement the RPi's boot faster than the router and hence in a ...

MySQL gets replaced with MariaDB in Stretch. The bind-address statement is in /etc/mysql/my.cnf in the [mysqld] stanza. If it's not there just add [mysqld] bind-address = 0.0.0.0 # The MariaDB configuration file # # The MariaDB/MySQL tools read configuration files in the following order: # 1. "/etc...

Re: Remote Access Problems MySQL - Fresh Stretch & DB install

Had not heard of NGINX before now, had to Google it.

Since using LAMP for a while I'll try to persist with it unless it has become a train wreck with the latest MySQL.

Re: Just out of curiosity, what x86 is RPi3 equivalent.

I know there is an array of specs, just in general I was thinking back to my first laptop (286, 40Mb hdd, 12Mb RAM Win3.1, cost 1 - 2 months pay) while I was setting up a new install on RPi.

Any way it looks like it's at least later Pentium series possibly considerably better.

Just out of curiosity, what x86 is RPi3 equivalent.

Does anyone have a feel for what old PC processor the RPi3 would be similar too? Something like 286 or 386?

Default User Accounts

Hi All.
I am setting up a RPi 3 to use as a VPN server on home network. I just wanted to make sure any default logins were changed.
Obviously Pi/raspberry login needs changing.
Is root a user? or is there an admin?

Have loaded up Raspian or is it Debian from NOOBS 2.1.0

cheers
Geeman.

Re: How to view file on RPi from PC or Android on same netwo

So tried all.
Ended up using Samba to access txt file and review entries.
Tried putty and now use it to shutdown or reboot (python script set up to auto start so only need to reboot when alter script).
Tried Apache but that seemed to mess up Samba access.

Re: Using capacitor buffer across GPIO pins

Placed capacitors across pins to ground. Ironed out 99% of false triggers so now putting extra code around one gate that is sensitive to high winds false triggering. Just trying sleep 0.5 seconds on first trigger then retest state of pin.
