Hello!
I'm looking to do some testing using the OctoWS2811 library to drive some WS2812b leds.
I know I need to use a buffer to bump the 3.3V signals to 5V to be able to drive the leds, but have a small question that I've been so far unable to find answered anywhere.
The recommended IC is the 74HCT245, I'm wondering if the 74HC245 would work as well?
From what I can find on the spec sheets, the difference lies in the supply voltage, which should be ok for the HC version, am I wrong?
I know there is an adapter shield, but it's really overkill for what I'm trying to do, I just need something simple and straightforward to experiment with.
