I have two implementations of a dig quad with tm1814 running WLED 0.14.0-b1. One implementation has 4 segments with a mix of length and AWG wire while the other is a bench setup to diagnose problems. The bench setup is 12 inches from power to the dig quad and 12 inches to a 18 inch strip using 16 awg wire throughout. In both setups, the LEDs briefly go into demo mode/lose data/flash red periodically. This happens when on or “off”. The 4 segment strip seems to affect all segments at the same time which makes me believe this is a software issue and not a wiring issue. I have a similar issue with the bench setup with just the one segment. I’d like to start troubleshooting this and looking for some direction. The problem has been present while running both 0.13.3 and 0.14-b1. Anecdotally, 0.14-b1 seems worse.
So maybe some more information to help track this down. 0.14-b1 was crashing on both setups which explains the frequency increase. I’ve reverted back to 0.13.3 and have noticed that the first “pixel” (6 LEDs on the 24v tm1814) is unaffected when “off” but the rest of the segment is. So, when the segment flashes red (presume to be demo mode), LED “0” or pixel 0 remains off while the rest of the strip flashes red.
OK, compiled 0.14.0-b2, (March 8), with WLED_DEBUG and right near the last entry the TM1814 strip goes into demo mode for sub 1 sec and returns. I have a SK6812 as segment 1, GPIO 16, and the TM1814 as segment 2 on GPIO 4. There is nothing on GPIO 3 and 1 so that I can debug over serial. I don’t see anything in the logs that would provide a hint on the root cause but hoping someone else does. Only the TM1814 strip has an issue but then again, they behave differently when they “lose” the data line.
