I'm working on a LED POV project, and I'm using TI's TLC5925. It's pretty much a latched shift register with constant current sinking outputs. They have more advanced chips as well; some with digital brightness control and even PWM settings for each channel. It also has 16 output channels. Non-SMT versions are also available.â¢ Related QuestionsI2C address selection in PCA9685You can do both. What they mean is that, if you connect the pin to either GND or VCC, there will be no current wasted due to some internal pull-up/pull-down.But whether you connect it directly or through a resistor does not really matter. I suggest you connect them directly for simplicity.------Community Wiki and SO meta-discussionUservoice introduces itself with the following phrase, presumably a statement of purpose: If you've participated in the Stack Overflow beta, perhaps you've found a bug, or you've got an idea for new or enhanced Stack Overflow functionality.
