WS2812B ring problem
I need help !!
I am modifying a ciclop to implement the excellent solution offered by FabScan.
To date, the solution is almost functional: the camera is OK, the control of the 2 lasers is OK, the motor control is OK.
However, the WS2812B ring light cannot be operated.
My ciclop is equipped with a HE3D card, on which I did find a connector with the GND, VCC, MI and MO plugs.
I connected MO from the board to MI from the ring.
Someone would have any idea ?
Thanks in advance.
Sorry for the late response, can you post some pictures of your board please? There are several versions/clones of the HE3D. Some pinouts are different.
Have you already tried it like described in the docs: https://fabscanpi-server.readthedocs.io/en/latest/steps_ciclop.html#connecting-leds-ws2812?
It seems impossible to put pictures on the forum ( No more attachments are allowed today ??).
Also, here is the model of my card (found on a merchant site) : https://mikroelectron.com/Product/3D-Scanner-Kit-HE3D-Ciclop-Advanced-Laser-Scanner-DIY
I tried to connect the WS2812B to MO of the 6 pin connector present on the board, but there is no signal.
This is the only connector visibly available, but perhaps not properly addressed in firmware.
Thanks in advance for your help.
I've more informations :) . The board use a Mega388p in a TQFP32 package. The 6 pins connector is the ICSP connector, and the MO pin is connected on PB4 / PCINT4 / MSIO.
So, to connect the WS2812, I suppose you have to direct the signal to PB4, but also disable debug mode (disableDebugPorts())?
And maybe also something else? I found this info on other forums but I have no idea how to do it.
Is there a solution ?
First of all, thank you very much for your precious help.
it will be very difficult to solder a wire to the pin of the circuit.
I just ordered a ZUM scan card to put on an arduino UNO that I have in stock. I would then be in the configuration of the site, with the correct connectors.
I shouldn't have any particular manipulation or will I have to load the bootloader on the UNO ?
I,ve now install a solution with Arduino UNO and a board ZUN Scan. My WS2812B is now running.
It's just a first steep for me, because I can't obtain a good scan. But that will be for a another ticket .
