Thanks spl23! The original motivation here is that I have some old circuit diagrams I wanted to re-use for some projects that we're updating to Scratch 2 (I work for a small nonprofit in the US with our own custom RPi kit). I was trying to avoid changing the diagrams if possible. At this point it so...
Thanks - I think that resolves my confusion; previously we were using a third-party solution (http://simplesi.net/) and I think that initialized all pins to pull-up. Unfortunately I still haven't had any luck figuring out whether you can toggle this manually in Scratch 2.
Hi - I've tried searching for this topic on Google and the forums with no luck. For Scratch 1.4 the documentation includes how to set internal pull-up/pull-down resistors using the "broadcast" block: https://www.raspberrypi.org/documentation/usage/gpio/scratch1/README.md I couldn't find any such inf...
It's a long story as to why we don't update more frequently so I'll spare that explanation here. You're right though, I checked and we didn't have any problems with the first batch of our kits, this started happening with a re-order of a couple hundred units. The failure rate is low (under 3%) so sp...
Sorry if this wasn't clear in the original post - this is a kit with a pre-flashed SD card. Changing anything on the card is not an option at this point. I was just trying to reverse-engineer to figure out what happened and it appears that overclocking was the problem. The crash happens during boot,...
Circling back to answer my own question...looks like the problem was caused by overclocking. I forgot to mention in the original post that our SD card comes overclocked to Turbo. If I reset overclocking to "none" on a card using the working Pi, then the other two Pis boot fine. If I set those back t...
I work for a small nonprofit that developed a Raspberry Pi kit and curriculum based on the Model B+. Our kit includes an SD card with slightly customized version of Raspbian from 2014 (we don't have the manpower to keep up with hardware/software updates as fast as they come out, so this is what I've...
I did notice that over 3.5mm, each sound has a pretty long fade-out that seems to last a second or two - much longer than half a beat or whatever I had set in the block. So, maybe you can't actually hear that over HDMI (it's quieter than the initial noise), but technically it's still playing, causin...
And that did it. Sorry for the wild goose chase. Made sure to expand the filesystem first and went back to square one. Everything works fine. I will edit my original post so anyone else who stumbles across this doesn't go down the same rabbit hole. As I believe you mentioned somewhere, sound quality...
Next attempt: I opened timidityinstall.sh and noticed that it has this all as one line: sudo apt-get -y install timidity timidity-daemon fluid-soundfont-gm fluid-soundfont-gs As usual, Linux noob here but maybe the "-y" has something to do with the previous error message (that was missing when I ran...
Haven't had a chance to try any of your step-by-step directions yet, but small update...I actually have a black screen with a single blinking cursor all the way in the upper left corner! That seems better than a totally blank screen. At least it has a pulse.
Yep. Using Win32DiskImager to overwrite the card with brand-new Jessie, booting up, and not doing anything else before I try this. I'll try it again today...
Actually taking a look at the text when it installs - I'm guessing you're referring to this: cp: cannot stat '/etc/modprobe.d/alsa-base.conf': No such file or directory sed: can't read /etc/modprobe.d/alsa-base.conf.org: No such file or directory those are the last 2 lines before "Installation of Ti...
If it's worth anything - I rolled back to the September release of Jessie and tried again, and the installation worked without causing a crash. The instruments still don't work in Scratch, but I assume that's to be expected since support wasn't added until the November release. This is all on a Pi 2...
So, as for surviving contact with reality...would it be bad news if I told you it nuked the SD card :-)? The first time I tried this, after the reboot my screen just went blank. On the off chance I had previously corrupted the SD card somehow, I tried again with these exact steps: - flash fresh imag...
UPDATE for anyone reading this in the future: don't forget to expand your SD card's file system before attempting anything listed below! Hi, Could someone please give me a layman's explanation of "MIDI Instruments," what they are, and how to play them in Scratch? I've always noticed that the "set i...
Where should we look out for the more extensive documentation? I asked about the GPIO documentation in a comment on the blog post and got this response from Simon Long: "Scratch in this release includes a new GPIO server, which allows broadcast blocks to be used to set GPIO state and sensor blocks t...
Just wanted to jump in to say that I had the same issue in Windows 7 as of 11:30AM on Sept. 29th. File Explorer wouldn't extract the .zip file, gave an error that it needed 734 PB. Downloaded 7zip and used that instead, worked fine.
First off, I realize that there are other posts about video problems in Epiphany, but I could not find one describing this exact problem (I also used google to search site:raspberrypi.org in addition to the built-in forum search). My problem: videos in Epiphany always play through fine the first tim...
I looked around Epiphany's preferences and history settings and couldn't find a way to disable automatic loading of tabs from the previous session. I'm doing something where I'm testing a single, local copy of a page so it's annoying to always get 2 tabs of the same page each time I re-open it. Does...
I have been searching for an "official" answer to this. At first it seems odd to me to increase the total power draw capability to 2A, but only make 600mA available to the USB ports. The closest explanation I've found so far is from a forum moderator in this thread : If anyone has a B+ board, there ...
No idea, that's what I'm trying to find out. If that is what they do, I'm not 100% clear on how to do it. Maybe I want to do this? http://www.raspberrypi.org/use-your-desktop-or-laptop-screen-and-keyboard-with-your-pi/ But I'm not totally clear if that makes the RPi's desktop a windowed application ...
Thanks, but I'm not sure if the Pi has enough horsepower to run this effectively. I tried it and the GUI stopped responding when I tried to select the recording area. I used the command-line utility instead and then it took over an hour to encode a 41-second video with default settings. The whole vi...
