Forgive my newbness. I'm JUST now getting into the world of Arduino and microcontrollers. (It's been C# most of my life.)
I was able to successfully get a couple TLC5940s working with multiple LEDs (and was surprised at the simplicity). However, I can't find a good answer for my question.
I've seen that you can't daisy chain the TLC5940 (easily?) with another SPI device, specifically a micro-SD card.
Using a Nano 3.0, can I use the TLC5940 and an SD card? I don't want to constantly write to the EEPROM. For what it's worth, it doesn't HAVE to be a TLC5940 if there is another inexpensive PWM option out there to drive 20 - 30 LEDs.
Thanks in advance, Kyle
