Very good

The problem is that the source was for an older version of avrgcc. Include compat/deprected.h and try to compile again. alternative you could define the cbi, sbi macros yourself:
#define sbi(port, bit) (port) |= (1 < < (bit))
#define cbi(port, bit) (port) &= ~(1 << (bit))

See articles powerRGB and tinyRGB to find schematics & source-codes.

The programming part is not shown here in the circuit. But you can program it like all other AVR connecting MISO (PB1), MOSI (PB0), SCK (PB2) and RESET (PB5) to an ISP Programmer.

How do you download code to it?

Comment on AD9833 / AD5932 Interface by David Fowler

David Fowler — Mon, 30 Jul 2007 05:43:35 +0000

Neat! I am playing with the AD5932. Interfacing to the Ardunio to make a bench USB controlled function generator. Found your site when I went looking for some sample source code. I am haveing troube getting the device configured. I dont want a scan right now, just a fixed frequency output… Do you have any source code which could give me a clue?

Hello Tobi,

can I download the PCB of the ausioFM at your homepage?

The one shown in the link is o.k. for powerRGB. I bought mine via Ebay from a Seller in China.

Hello Tobi,

which RGB LED you’ve used and where you bought the led? the only RGB LED I find here is the http://www.led1.de/shop/product_info.php?pName=prolight-power-rgb-led-3-watt-ga-p-308&cName=prolight-power-leds-prolight-power-rgb-leds-c-8_73

Hello Andreas,

sorry for my looooong delay to answer your question about the ATTiny45 code.As i have no Homepage for downloading, i ask Floe for help:
Which is the best way to transfer my modified Code to Andreas??? (May be, Floe is also interested to check the Code?)

Best regards from Vienna
Robert

I had problems with some MOSFET’s and with the resistors it worked well…
Leave at least the series resistor (r1-r3) to limit gate charge currents.

Why you have those R4 to R6 + Vcc connections? This would work better without them.

Comment on AD9833 / AD5932 Interface by theFloe

theFloe — Tue, 13 Feb 2007 12:20:39 +0000

Sorry but I never finished the project. I only did the schematics drawings and some tests. For this I used the Windows Software provided by Analog for Interfacing the AD9833. So for your project you will have to use the AD5932…

i wan to make a single scan waveformgenerator which will generate a frequency from7.5MHZ-22.5MHZ with the help of a ATMEGA8535 microcontroller.so i want your help.

Comment on powerRGB by theFloe

theFloe — Mon, 05 Feb 2007 08:38:13 +0000

Hi,
any N-Channel, Enhancement, Logic level MOSFET should be o.k. You should also select some with low Rds_on. For the STORM hack I used some IRL3103 ( http://www.irf.com/product-info/datasheets/data/irl3103.pdf ).

Hope that helps… Tobi

Can you provide some part # for the MOSFET that will work with powerRGB? I’m not all that familiar with them, and a stab at Digikey’s search function didn’t return anything useful. Thanks.

BTW, I find this a much simpler circuit than others I’ve seen, and I like the extensibility to cover higher power RGB. Thanks for posting!

Hello Tobi, hello Robert,

at first a happy new year and I´ll hope that you can understand my bad english.
I think that I´m the “Someone” who reports earlier from this “blackout”.
Now I have test allso the new code for the Tiny 15 and I can say:
“It works fine and now there are no “blackouts” to see. Great work.”
Sometimes I´m also think that it wood be fine, when there are some adjustment-points in the code to control dimmtime/color-change-time.
Please let me know, if you Tobi or you Robert implement this features into an other new version. I´m also interested on the adapted code for the Tiny45. Robert, can you send me this code or where can i find the code in the www ?

Best regards
Andreas

Comment on Interfacing an LCD by Martin

Martin — Fri, 29 Dec 2006 18:52:24 +0000

Hi
very nice … now search a working LCD … my other problem … I’m using original ASUS software …
Is there an unused bit at the port? Maybe it is possible to use a backlight lcd and switch light on / off by time daemon or manual with this bit?

I’ll test this version after new year …

Thanks and have a good new year
Martin

Robert Ibener — Fri, 15 Dec 2006 11:40:10 +0000

Hello Tobi,

it´s hard to say that i need it faster/slower.It depends on my applications (Moodlight-Stuff).
For shure i need some adjustment-points in the code to control dimmtime/color-change-time.With only changing the Timer0/1-Prescaler my problem is not solved.

But dont get nervous about this.It is not soooooo urgent and (i think) it´s only my personal wish for my PERFECT application.

In the meantime i have adapted your code for a Tiny45.

Best regards
Robert Ibener

I’m working on it. Do you need it faster or slower?

Comment on tinyRGB by Robert Ibener

Robert Ibener — Thu, 14 Dec 2006 16:41:22 +0000

Hello Tobi,

thank you for your new version.It works as expected now, even i am missing some features built in in the previous version (for example:
adjustable dimming steps,adjustable time of color-change,e.t.c).
I will try to implement above features into the new version.If you are interrested, i will send you the code, but it will need some time!

Best regards

so here’s the new version of the code. The fading has been improved and I couldn’t see any “blockouts” or “glitches” using an 1W RGB Led.

Someone reported this “blackout” earlier. I had a short look at the code then but couldn’t find the source. When I have some time I’ll have a look at it again.

Robert Ibener — Sun, 10 Dec 2006 11:55:04 +0000

Hello Tobi,
your code just fit my needs for my application.
The Program works fine , color-change is smooth, except for one small (but disturbing) side-effect:
When one of the LED (either R,B or G) dimms up (gets brighter) there is a short “blackout” during the dimm-up-process.With “blackout” i mean, that the LED which gets brighter will switched off for a very short (but visible) time, then continues with dimming.This “blackout” shows up randomly, sometimes at the beginning of the dimming-process,sometimes in the middle or near the end or even when the LED is fully on.The “blackout” is only in the dimming-up-phase visible.Dimming-down is smooth and o.k. I have simulated your program in AVR-Studio4 for hours to detect this “blackout”, but with no success.In AVR-Studio all seems to be fine, no reason for a “blackout” found.I have also tried several Tiny15´s but no change at all.
My Question:Do you know about this problem and (if available) can offer a patch to eliminate this “blackout” ??
Best regards and thank you for this great code
Robert Ibener/Vienna

The download link is at the bottom of the post and it’s programmed using avr gcc.

Hey

I’m building it to but bigger.
Did you program with bascom or with something else? Would it be possible to see your program??

Thx

Hi Tosin, no I’m from Austria and good luck with your project! Do you have a page describing the project and / or progress?

Great project! I’m actually doing something similar for my final year project at Uni. Are you Nigerian by the way?
