Hello all. I've just tried to install a FreeBSD snapshot, FreeBSD-11.0-CURRENT-arm-armv6-RPI-B-20140701-r268111.img to be precise and I've notice that the overscan parameters on config.txt aren't used. Other parameters are read correctly (for instance sdtv_mode or sdtv_disable_colourburst. Is this n...

Well it's red and blue swapped but green is okay. Do you only get this with framebuffer applications (e.g. X and standard linux console apps) or do you also get it with OpenGLES or openmax (e.g. hello_video, hello_triangle, penguinsopuzzle, omxplayer). Do you get it with (in config.txt) framebuffer...

It's impossible ! Red and blue are swapped. Cyan (no red) and yellow (no blue) are swapped. Green (no red or blue) and magenta (red and blue but no green) are ok. I've manage to get the same results with a fresh raspbian image, just downloaded from this site, the culprit triggering the effect is th...

anche perchè ora mi sono incuriosito anche io della cosa , e ho cercato un po in giro , ma non ho trovato proprio nulla a riguardo (per fortuna) L'Arduino e` una cosa completamente diversa dal Raspberry Pi. In ogni caso non sono cosi` convinto che i cloni Arduino fatti in Cina siano della stessa qu...

The first computer I ever used was my uncle's Commodore PET (maybe was the 8032, but I'm not sure) connected with a daisy wheel typewriter. My first computer was a sinclair QL, initially used with a big colour TV, then used with a green phosphor monitor, then added a Star NL-10 printer. Next, I upgr...

I think the best solution is to find a vintage IBM PC compatible at a garage sale or watch on ebay. To run Windows 3.0 you should emulate a full IBM PC system like qemu or dosbox does, someone anyway succesfully ran Windows 95 undeq qemu in the Pi, so this is feasible. Unfortunately what one finds f...

No, a charger is a fundamentally different device than a power supply! Its a bit hard to explain what the difference is between a charger and a power supply if you are unfamiliar with electronics. The main difference is that any charging circuitry in for example a GSM phone doesn't mind what kind o...

I've been looking primarily for a DAB radio adapter something to stream mp2 audio via the PI - http://www.ebay.co.uk/itm/R820T-ISDB-T-USB-TV-RTL-SDR-FM-DAB-Radio-Tuner-Receiver-Stick-Realtek-RTL2832U-/160868189288 Does anyone know if such a device is supported on the PI and whether the DAB or FM ra...

However, charging nearly 40eur seems excessive ($52). Current exchange rate should be about 26euro's. I suggest locating another supplier. For instance RS components? Yes, they're slow, but for half the price one could wait. Goods total 27.40€ Tax 5.48€ Standard Delivery (Despatch expected within 3...

While possible, even though a Pi is much much faster than an ATmega, it's going to be tricky due to the nature of Linux - multi-tasking, pre-emptive, etc. You need fairly accurate timing to clock the serial date out correctly and consistently. I think you'll be far better off looking for USB serial...

Hello all, It's possible to modify the GPU code to have an extra option for the composite output, making possible to have a progressive mode output? I was thinking to add a parameter, called sdtv_progressive_mode, that with value 0 makes the normal interlaced mode as is working now. With the value 1...

Strano... ma risponde ai ping?

Se risponde ai ping io verifichere che non sia un problema di risoluzione dei nomi.

Io proverei ad installare ad esempio un demone piu` semplice come fingerd e vedere se fa lo stesso scherzo o meno.

Io ho provato ad alimentarlo in tre modi, uno con insuccesso ed altri due con successo. Il primo tentativo e` stato con un alimentatore di una cornice digitale cinese, rimarchiata 'Autovox'. Il Raspberry partiva, ma si schiantava immediatamente collegando la ethernet. Il secondo alimentatore era un ...

L'utilizzo piu' divertente, fino ad adesso e' fare una SD con RISC OS.
Se avete una schedina da 2GB in giro consiglio a tutti di provare. Punti bonus se si usa l'uscita videocomposita.

So I think I found my solution using: 12" eTape Liquid Level Sensor http://www.adafruit.com/products/464 I do need to figure out how to interface this with my RPI though. I think I'll need to use an audrino in order to talk to the sensor but I'm not certain. If you're interested on a high and low l...

There are a lot of reviews saying that it doesn't work, but none are Pi specific. It appears to be for X Boxes and such like, giving an HDMI output and needing to connect to a VGA monitor. I suppose it's a cable used for a very specific purpose and for very specific systems, for instance when a lap...

I think I've found another problematic device. It's a USB to Centronics parallel interface with a Prolific PL2305 Parallel Port IC. It's marketed as "Vivanco Parallel Port Adapter" but I think its a standard item. I'm using the kernel from the latest rpi-update (but the same problem happened with th...

I'm opening a new topic here, because it's a more general topic. Actually, spoke to Gordon last night, and he is of the opinion that the vast majority of people will now see no problems, and he expects to be able to improve the USB again to reduce the impact on users by a significant factor, which s...

Tanti saluti dalla città dei quattro fiumi.

Try putting the following line in config.txt (but this should be a default): sdtv_aspect=1 That will force it to treat the composite display as 4:3. Also, I would recommend only using a max of 800x600 over composite - anything higher will be too blurry. add also sdtv_mode=2 and into RiscOS select 6...

But was the SoC designed with the ability to attach a normal USB keyboard as a requirement? Could be that the limitations of the USB controller did were known, but that it was considered acceptable for its purposes. When using USB for network or storage, missed packets are not fatal, and can simply...

Hey that will be the Italian version of the Raspberry, the model between the Raspberry Milano and the Raspberry Magenta!

But sometimes I feel that not casing electronics makes it really hard to test important aspects in practice. Therefore I wonder: Is there a case planned (either by Gert, the Foundation or third parties) for the Gertboard? Of course it would have to have lots of holes and slots, possibly with strain...
