Output device for boot messages

A lot of the questions around console messages seem to be about hiding them, but I want to know if it is possible for the messages shown as my Pi boots to be displayed on _both_ tty1 and serial0. I'd like to use the same image on multiple devices - but some operate headless, and some don't. 'cmdline...

Re: Accessing Sensor Data as non-root user?

I think I've manged to do this, basically I found that I needed to add a new rule to allow members of the 'video' group access to '/dev/fb1' and then put the users in that group if they want to use the display; as well as installing 'i2c-tools' and adding users to the 'i2c' group so they can access ...

Re: Raspberry Pi SIMH Networking

Re: RPi doesn't take connections (Wifi)

Good point - the instructions were written to be quite generic (I use the same configuration on my Linux PC as well as my Pi, and started with a 'minimal' install). If you are using a standard image most firmware is proabably already installed, as are the packages you need - However attempting to re...

Re: Noobs installation with VGA monitor

You can always create a config.txt in the boot partition your self. I'd try just copying in the one of the older image first and see if it works. Some settings (GPU memory split) are not strictly needed any more but I don't think it will stop the Pi booting if they are still there.

Re: Driving an R/C servo

There appears to be some advantage to using hardware PWM to minimize the load on the CPU and to ensure the pulse train is absolutly consistent - unless it is it can cause the servo to stutter which can burn out the servo motor. In any case I've worked out how to use the conventional GPIO outputs but...
