| Re: How do I give an I2C device an address? Posted: 04 Jan 2013 01:58 AM PST The easiest thing to do is look at the datasheet, this ought to tell you everything you need to know. Some modules have fixed addresses, some have software controlled addresses, some have hardware controlled addresses (where you have a set of pins that...     |
| Re: clock (second and minutes) Posted: 04 Jan 2013 01:56 AM PST do a search in the box at the top of this page for "clock display " or similar, there have been many projects to give you ideas     |
| Posted: 04 Jan 2013 01:56 AM PST I'm trying to extend the USBHost/ADK lib to ADK2012. I'm interested in the audio output. Basically, I want to know the audio latency of such a solution. So far, I find the correct interface (audioIf=1) & endpoint. I set the correct device configuration...     |

| Posted: 04 Jan 2013 01:52 AM PST Quote Why not just use a 5V wallwart? Ah, perhaps I should have mentioned, this circuit is an add-on to an existing model led lighting installation that is running off the 12v wallwart, and the guy I'm making it for wants just one power sourc...     |
| Posted: 04 Jan 2013 01:18 AM PST math.h is included in the Arduino.h header file, which is included in every .ino file.     |
| Re: AS1130 Ongoing Discussion 132 Individually controllable, PWM LED driver Posted: 04 Jan 2013 01:17 AM PST Here you can see the SDA and the SCL. What's strange is the ACK...because if the last byte is sent then there shouldn't come a ack before the stop bit...     |
| Posted: 04 Jan 2013 01:17 AM PST I have just started to learn programming the Arduino and I am going through some simple examples to get a better understanding. I have just tried an example that uses the sqrt() function, part of the maths group. I couldn't understand why the example...     |
| Re: not declared in this scope Posted: 04 Jan 2013 01:13 AM PST Indeed you have to spell consistently including case to program. Or use an editor with auto-complete on variable names. I would be interested in such an editor. Can...     |
| Re: Idée de projet pour débuter Posted: 04 Jan 2013 01:11 AM PST Merci pour ta réponse ! Effectivement j'étais au courant que le Raspberry était beaucoup plus limité en terme d'extension. Mais comme c'est un premier projet je me suis dit que ça valait le coup. Il sera toujours tant d'acheter quelque chose de plus ex...     |

| Re: uso particolare 7805 - data logger per auto Posted: 04 Jan 2013 12:57 AM PST Anche se nessuno si espone, stamattina sul bus ho avuto un paio di idee ed ho letto qualcosa in giro:  ho messo il diodo prima della resistenza per evitare "giri strani" d...     |
| Re: Problema bitshift uint32_t Posted: 04 Jan 2013 12:57 AM PST non crei problemi è dato dal fatto che nonostante lo shift di bit il valore non sfora mai il byte di lunghezza? Il problema lo hai solo se shifti verso sinistra perc...     |

| Re: Problema bitshift uint32_t Posted: 04 Jan 2013 12:52 AM PST Ok, grazie, lo provo subito. Supponevo che mi ero perso qualche pezzo. il punto che Code: uint8_t internal_inputs =((PINB & 0x06)>>1) + (((PIND & 0xf0)>>4)<< 2) + (((PINC & 0x0c)>>2)<< 6); non crei problemi è dato dal fatto che nonostante lo ...     |
| Re: AS1130 Ongoing Discussion 132 Individually controllable, PWM LED driver Posted: 04 Jan 2013 12:49 AM PST Okay thanks mate! I'm trying and trying but it still doesn't work... I optimized the code that SCL is now 90kHz. And to see if the driver is working I'm sending only the CLKSYNC-byte. So I'm measuring it but the oscilloscope gives me a really strange s...     |

| Re: Idée de projet pour débuter Posted: 04 Jan 2013 12:49 AM PST Pour commander une lampe, le Raspberry Pi peut effectivement se substituer à l'arduino. Par contre comme il ne dispose que de très peu d'entrées/sorties ses possibilités d'extensions sont limitées. Ce projet pourrait intéresser [url=http://arduino.cc/b...     |
| Posted: 04 Jan 2013 12:48 AM PST Quote I already discovered that UNO isn't capable of doing any image processing (is there any that can?) It depends what you define as "image processing".If all you need to do is locate the brightest spot in a low-res 2D image, or a mid-res ...     |
