It should run with those drivers. But when it is running you need to do some additional tweaks on the HAT. (see https://fabscan.org/community/hardware/fabscanpi-hat-and-a4988-driver/#post-822 )
Let's solve things one after the other. We should start with the motor. Can you post the motor type please. We need to find out if your wiring is correct and the coil pairs match like it is described in the docs.
When the motor is running we will find a solution for the LED issue.
Yes, thats it.
Meanwhile the Motors runs correct. The Lasers also.
But the LED´s don`t work. So the Calibration won`t work too.
I think the Data-Signal is lost.
Is there another way to connect the Data-Signal (PI-Out etc)?
@archeotro
Have you solved this issue yet? if not, you might check continuity from the arduino chip to the ring light, and from the power supply entry on the board to the ring light. I have attached 2 photos of your board and light with annotations to guide you.If those are good then you might test the ringlight with another arduino using the "fastLED" library (this is a link to an instructable https://randomnerdtutorials.com/guide-for-ws2812b-addressable-rgb-led-strip-with-arduino/ )
please report your results. good luck
Thanks for the Reply! :)
I meanwhile get an new FabScanHat from Waterott, because my building-charge have no right boot-loaders.
They delivered me a new one, without I have asked about it.
Thanks a lot to Waterott!!!
But my Problem with the Ring-Light is also on the new Hat, that I think I get an already damaged Ring-Light?!
There is already no Function on Power on the FabScan or also on Start Calibration, that the Calibration stops at 35sec left and ended with the Error that the Laser can not be estimated.
Do you have a solution yet? I have the same problem, the ringlight itself is ok (colorpalette works), the HAT delivers 5v and Ground For me it looks like the HAT does not provide a data signal....
I had some exercise with Corona.
But there is no solution yet.
I have no fine Tools to measure the Chip, so i had buy me a new Ringlicht, but this do also not work.
It must an Error on the Hat!!!!!!!!
Or have you a solution found????
In the next Days I will write to Watterott :( :( :(
