The LT3746 performs full diagnostic and protection against open/short LED and overtemperature fault. You could get a driver chip or several to do it for you (like MAX7219), or just use I2C/SPI I/O expander chips (such as MCP23017). share|improve this answer answered Dec 21 '12 at 10:14 John U 5,22111025 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google A bit of 0.1" header is also included so you can solder it on and plug into a breadboard.To use: Power V+ with 5-30VDC, and connect ground to the common ground.

It’s not your LEDs or code…it’s biology! The STP24DP05 has a dedicated pin to activate the outputs with a sequential delay, that prevents inrush current during output turn-ON. Certain demo boards are also available for sale via credit card on this website. You can also Multiplex the LED's, as you said in a matrix; however I think you can do this with 24 I/O pins (12 x 12 grid = 144). http://www.linear.com/product/LT3746

You won't even need current limiting resistors with such parts. For example, the electrical matrix could be 11 rows of 12, with five of these rows appearing in each of your 60-LED physical rows. –Dave Tweed♦ Dec 20 '12 at 0:24 Join them; it only takes a minute: Sign up Here's how it works: Anybody can ask a question Anybody can answer The best answers are voted up and rise to the

The high clock frequency, 25 MHz, makes the device suitable for high data rate transmission. Obviously the physical arrangement of LED's would still be 2x60 and 1x12, but the electrical arrangement could take advantage of a 12x12 multiplex. Would it be a bad idea to periodically run code formatters on a repository? Arduino Rgb Led Driver LED Tricks: Gamma Correction RGB colors off?
