I would like to use the LED driver with 12 channels for several RGB LEDs. The example in the documentation only shows input from two lines: CI and DI. The RGB LED requies three inputs. What am I missing? Should I have purchased the 24 channel driver?
Thanks

Re: LED driver 1455
The board uses a serial protocol to transfer all three bytes of color information over CI and DI. This information goes to the TLC59711 chip. That chip, in turn, drives the RGB LEDs.

Re: LED driver 1455
So how would I confiure the three leads going into the two input ports? Or does it matter?
Thanks
Thanks

Re: LED driver 1455
You don't configure three leads. The PWM module is a SPI-like device in which the MISO and chip select lines are not used. So you only have clock and data. You don't connect R G B lines to the module.

Re: LED driver 1455
I have reviewed the documentation on the LED driver and understand better how to proceed. I am also researching using SPI with Arduino.
Thanks for your assistance and patience.

Re: LED driver 1455
You don't really need to know anything about SPI. Our library takes care of that for you
