Re: irexec not doing anything

Glad I could already be of some help. For the rest, I would probably need to see your lircd.conf. However, I am going to make one more guess before you post that. If you literally followed the guide you linked to in your first post, your probably gave the "1" button the name "KEY_1" in your lircd.co...

Re: SqueezePlug Version 7 available

Thomas, Great work indeed. I used your scripts to learn how to configure my current LMS+squeezelite setup that uses a HifiBerry for output (and used the full squeezeplug for my previous setup which had a Behringer UCA-202). In my experience they HifiBerry works great. It seems to have better signal ...

RPi behind Netgear router may prefer openntpd

I recently found a solution for the issue that my Pi stopped syncing its clock after switching my home network from a Linksys to a Netgear router. But I don't fully understand it and don't know how general it is. The purpose of this post is therefore two-fold: If you have a RPi that often fails to s...

Re: TFT01-2.2S with notro's fbtft module

In that movie the display only turns on when the boot process is already well on its way (to be precise: when the kernel modules are loaded).

this is about kernel modules... no need to do anything with rc.local. /etc/modules and files in /etc/modprobe.d are all you need to worry about to get a working framebuffer device for your tft module.

Re: Easy and cheap voltage and current measurement

Curiosity question that can probably only be answered by someone who owns this device:
does it report currents that are going in the other direction from what it would expect as well? that is, if I put it between the pi and the hub that is backpowering my pi, will it tell me the backpowering current?

Re: Need help getting LCD Module to work

A few questions to perhaps help you get further. 1. If you connect the BL to 3.3V, and GND to GND, without connecting anything else, does the backlight turn on? 2. Did you follow the instructions on notro's fbtft wiki for installing a kernel that supports SPI TFT devices? 3. did you make sure /etc/m...

Re: Need help getting LCD Module to work

I would not connect the VCC to the 5V rail unless you know exactly what the LCD module looks like on the inside. Chances are it'll end up putting 5V on GPIO pins which means the end of your Pi. Better connect it to one of the 3.3V pins. Also, the DIN pin will need to be hooked up to something (MISO ...

Re: Squeezelite at same time as raspbmc

I have never tried this but I don't see why not. Squeezelite and xbmc each have their own settings for audio output. I would guess that you can run squeezelite with a usb sound card (google is your friend) in the background while having xbmc over hdmi.

Re: USB Audio - I hear inputs on the output at all times

Couldn't resist looking up the manual of the UFO-202. It refers to the RCA-outs as connections for a "monitoring device". Maybe they are fixed to behave as monitor connections in the hardware? Would be a bit silly if you ask me, but given their intended purpose (to digitally record your vinyl collec...

Re: USB Audio - I hear inputs on the output at all times

My hunch:
If your device is the UCA-202 or a similar model, you can probably stop looking in software for a solution: the device itself has a "monitor" switch. My guess is that's "on" now. Try setting it to "off".

I own the grey-colored brother of that behringer: the UCA-202. It's great.

It's actually what I was thinking of when promoting cheap DACs in my previous ...

Re: RPi to 4 channel audio amplifier

Combining two outputs of a 7.1 card (front and back) into one input (with a simple Y-cable?) on your amp is not a good idea. If your amp does not have enough channels to keep them separate, it would be better to leave the back output of the sound card unconnected and just channel the front output to...

Quick Question.... Can we still use the SPI bus for other stuff if we need to by freezing the lcd? There are 2 chip select (chip enable) pins exposed on the main GPIO pin header so using two devices at the same time should not be too hard (they should share clock, miso and mosi, each has their own ...

Re: Connecting 3v relay to pin 11

Here's another example that may be instructive (although it is more complicated than what you need exactly). It controls a 5V circuit containing a relay from a 3.3V GPIO pin (in this particular case to automatically cut the power to the pi a few seconds after a clean shutdown). http://www.raspberryp...
