RGB & RGBW LED MALFUNCTION 3.5.1
-
It seems to me, that after the update to 3.5.1. the LEDs controlled by the MB6HC on io.port have stopped working correctly.
The same LED strips connected to the Dotstar port continue to work properly.
in tests done with multiple LEDs (see instructions in config.g at the end of the file) the behavior of the various LEDs is very similar.
After the M150 command e.g.:
M150 E1 R255 U0 B0 W0 P50 S1 F1
M150 E1 R0 U0 B0 W255 P50 S2 F0
The first LED is light green, while the other two are correctly white. If I give the command to turn everything off e.g. M150 E1 R0 U0 B0 W0 P0 S3 F0 the first LED always remains lit green.
After turning on the printer if I do homing, the LEDs in the extruder automantically light up green. (I have no active macros).
I would like to avoid downgrading to 3.5.0 because I would have to update the mainboard, toolboard and DWC.
I would like to receive some suggestions or understand if I'm doing something wrong.My config.g

Are your LEDs GRBW vs RGBW for color order?
If you try and send green to the light is it red?

-- Are your LEDs GRBW vs RGBW for color order? ---
To do an accurate test I installed a 155-element RGB LED strip in the dedicated LED port (working perfectly), a 3-element RGBW LED strip on the io.8 port, a 4-element RGB LED strip on the io.7 port, and a 3-element RGBW LED strip on the io.5 port ( like in my config.g)-- If you try and send green to the light is it red? --
Of the 3 LED strips connected to the io.port of the MB6HC, the first LED on the strip always remains green with any command sent. The first green LED never turns off with any command.
The 2 RGBW LED strips are buy new for the Voron stealthburner...It is possible that the upgrade from Fw. 3.5.0 Rc4 to Fw. 3.5.1 could have caused this malfunction?
Since the printer is now fully functional, I wouldn't want to experiment with a fw. downgrade, since I'm in SBC mode.

@Gianluca I've just tested LEDs on io ports on a 6HC, and see the same as you, ie first LED is stuck green in RRF 3.5.1. I went back and tested on 3.5.0-rc.1 (works correctly), rc.2 (works correctly), and rc.3 (first LED stuck green) too. It seems there was a regression in function between rc.2 and rc.3. I've also tested in 3.5.1 on Duet 3 Mini 5+, and LEDs on io ports work correctly, so this seems to be specific to 6HC (and probably the 6XD, too).
I have raised an issue on Github, so @dc42 can fix it. https://github.com/Duet3D/RepRapFirmware/issues/996

@Gianluca @dc42 has fixed this bug, and will be included in RRF 3.5.2 when released. See https://github.com/Duet3D/RepRapFirmware/issues/996

@droftarts I'd be interested in whether this affects NeoPixels controlled by a NeoDriver I2C card, because I'm having exactly that problem - the first LED often lights green at startup.
It seems like this probably wouldn't affect the NeoDriver, but I'd love more information about what caused this and what the fix is, in case either Adafruit or I could do something about the same problem with the NeoDriver.
I'm also finding it's easy to start getting "I2C Transmission Errors" requiring a power cycle. Adafruit commented that it sounds like a flaky I2C interface (not on their card, of course!); I wonder if all this might be related. I know the timing is critical on NeoPixels. I'm not sure which side of the NeoDriver these 2 problems are on.
-
@DonStauffer the issue on the 6HC was that the loop body that generates the Neopixel data straddled a cache line boundary. This meant that on the first iteration of the loop (which handles the green value of the first LED) there was sometimes a delay while the cache line was being populated from flash memory. This delay caused the first (most significant) bit to be extended enough so that if it was 0 it could be interpreted as 1, or for the second bit if it was a 1 to be interpreted as 0.

@dc42 Thanks for the information.

@dc42
Thank you!
Could the change already be present in the first Beta versions of 3.5.2? -
@Gianluca we haven't yet issued any 3,5,2 beta versions, however we expect to release 3.5.2-rc.1 within the next few days.
