Re: What will happen if I drive LEDs in parallel from a TLC5947?

Posted: 30 Dec 2012 01:47 AM PST

If you are using the TLC5947 to drive a lot of LEDs, then you need to take the power dissipation of the chip into account. For each channel, it is the voltage at the output pin (which is the supply voltage less the LED forward voltage) times the output...

Re: How to avoid code duplication in a function?

I'm clearly missing something here; why not pass the relevant variables by reference?

I suppose I could use a function parameter, but that doesn't allow me to acc...

Re: SerialException with Arduino v1.0.2 and Leonardo

Posted: 30 Dec 2012 01:45 AM PST

I'm seeing the same exception with my Arduino Micro. Arduino is v1.0.2:


Binary sketch size: 15,902 bytes (of a 28,672 byte maximum)


processing.app.SerialException: Serial port '/dev/tty.usbmodemfd111' already in use. Try quitting any programs that may ...

J-type Thermocouple question

Posted: 30 Dec 2012 01:08 AM PST

I've just purchased a Mega 2560 R3 board and am doing some temperature control as well as ethernet comms. I intend to have, at minimum, 3 thermocouples (preferably 4) as well as an ethernet port. If I looked at these correctly, the ethernet port will n...

Re: Ideal Battery Hardware For Project

Posted: 30 Dec 2012 01:07 AM PST

Nice.  The reason I said to take the 5 output volts and put it on the VIN pin is- that the Arduino's voltage regulator will not do anything as it's already 5 volts.

La funzione F() è già definita nel core di Arduino, non puoi usarla per altre cose.  smiley-wink

Vero, però F() è una funzione e non un nome generico, ovvero puoi tranquillam...

depends on the language lua for example

Re: Collegamento bus tra diversi Arduino

Posted: 30 Dec 2012 01:04 AM PST

Ethernet é un po costoso ma in quel caso potresi usare un PC come nodo master.
Dei bus tip I2C o SPI non funzionano con le distanze necessarie tra i Arduini.

È meglio che usi un bus che si usa anche in Domotica perché in questo modo puoi aggiungere anc...

I also can't use an inline function, because although the code in those is supposed to just replace the function call, the compiler can decide not to do that which means trying to call variables local to the function holding my switch statement ...

uh hmmm, no.

But i'll certainly try it sometime smiley

Re: Standalone Setup

Posted: 30 Dec 2012 12:44 AM PST

One of the annoying things about using the AVRISPMKII is that I have to use one driver when using it with Arduino IDE, and switch to a different driver when using it with Atmel Studio. It would be great if the Arduino IDE could use the driver that ship...

Re: Can't complile TimeAlarm library without getting error Alarm out of scope

Posted: 30 Dec 2012 12:41 AM PST

Thanks. I'm still working on this. Seems to be regressing - I can no longer figure out an order to compile the arduino and the processing without getting serial port related errors, and I can't seem to get the time print any longer in the processing mo...

Re: 16x8 LED matrix driver IC

Posted: 30 Dec 2012 12:40 AM PST

Looks like it's either a TLC5920 or a TLC5940/74HC595 combination depending of LED matrix type.

TLC5940/74HC595 won't work if it's common cathode...

If you have enough money to spend on the kind of telephoto glass you are depicting - you have enough money for a serious professional solution.

I do not have a "schematic prog" so as to give you a diagram.

If you have a way to take a digital picture - then you have a way to post a schematic, provided you ...
