The information provided in this post https://forum.pololu.com/t/additional-chassis-level/41/1 corrected my issue. It was nice to know that someone else had the same issue, and that it wasn’t a wiring issue. Unfortunately, I had already purchased some pwm based strips to meet my deadline as a prototype device. The customer prefers the quality and shape of the Pololu strip, and I returned to see if I could get them working.
Now that I have returned to these, and I am able to control the strip appropriately, I’m running into timing issues. My sketch is time based, using the milliseconds from the start of the cycle as a timer. While this works with the pwm based strip, the process of writing to the strip seems to actually slow down the internal clock. A process that should take 10 seconds will take close to a a minute. If I take out the comment out the .write commands, the clock goes right back to normal. Is this expected? Is there a way around this? This project requires the internal clock to be accurate.
Thank you,
Ken
