hi all,
does anyone know of a rgb led driver that could be controlled via a 8-bit parallel port? the idea is to control this driver from a ds2408 1-wire slave. the ds2408 is an addressable 8-i/o device....

if you do want to use the rc then you can use a transistor or fet to increase your power to the led.
there are a lot of diffrent circuits to make a sine wave, but all of them will output very low power. all you need now is to increase your power with one of the...

hello every one,
i want to control ( using p89lpc921) the dm163 ic to help in an rgb color system as a led driver.
it has a pulse width modulation unit and other stuff as you know, i really don't understand how it works. i couldn't...

hi all
i'm thinking of building a pulse led driver circuit. rather than just flick on then off,
the led slowly up to full brightness then down again, cycling every 1 to 1.5 seconds. a triangle wave generator can do that, but i need the...

time, how long will it take? fully depends on you. nobody can tell you.
and now, a small example about driving of led panel.
assume, you have 8x8 rgb matrix and want to show full-color static picture.
assume, your panel has 1/8 duty and you have to scan... for now;
i just want to implement a picture on my led panel. i know fpga is need for big applications but cant i do it with microcontroller and driver ic s ??
rather, no. microcontroller can serve signboards with text features. displaying of a graphic...

nevertheless it is quite an interesting subject.
in any case i have been thinking along these lines for some time. i started making a small matrix, 4 by 4 rgb leds with 6 as1109 constant current led controllers, controlled... then you could do use a different type of controller. i have seen an application note from altera on how to configure fpga as constant current led driver. not sure if this is cost effective or not.
i had not thought about vga interface. this seems like too...

hi all,
i'm designing a device with a pwm-modulated rgb led module and need to measure ambient illuminance (from the environment) with a sensor mounted in close proximity. i'd like to use the same sensor to monitor led output, so i can't... sensor.
one obvious way to go, because the led is driven by a pwm signal, is to only measure light during the off periods. thus, a photosensor + driver that behaves like a pixel with an electronic shutter and integration control would be very nice. does...
