Im working on a word clock project. Using

  • arduino (nano) WS2812 with FastLED lib,
  • D3231 RealTimeClock with ds3231 lib,
  • Bluetooth HC-06 module with SoftwareSerial

I want to use the BT connection to setup the clock. But when receiving data from the BT module, it seems that the received characters are completly random data.

When I comment out the FastLED.show(); line from my sketch, the characters received from the BT module are all correct.

I’ve read some threads about this problem between FastLED and SoftwareSerial in different discussion boards, but there wasn’t a solution I could use.

Any hints on this issue?

A quick search (http://bfy.tw/7F0P) turned up this, might be helpful: https://github.com/FastLED/FastLED/wiki/Interrupt-problems :slight_smile:

Sounds like a cool project, looking forward to seeing some pics/video of your build!

this is my BT handler I use for WS2812. With this I can select animations and global settings

Thank you guys. I got it running.

A project documentation is on github https://github.com/chess-levin/WC64 . It’s still the last version of the wordclock without BT.

There are some videos as well.

Glad to hear it, what was the problem? What’d you have to change?
