Hello. I’m new to the forum.
I purchased a scroll bot kit and am not having any luck getting pixels to light up.
Soldering of the headers appears to be solid.
The scrollphathd sw installed correctly using:
curl https://get.pimoroni.com/scrollphathd | bash
except for errors installing the smbus for python2 and python3.
After researching this issue and installing smbus separately it appears to be working.
I have enabled Ic2 and get back numeric values in the the matrix when irunning:
sudo i2cdetect -y 1
The scrollphathd does have 5 volts and 3v on the appropriate pins.
When attempting to light a pixel with
set_pixel(1, 1, 1)
the code runs without error but no pixels light.
Any suggestions on how to best troubleshoot this problem?
