Hi there! I’m using a Raspberry Pi 3B+ setup where the ScrollphatHD is connected to. This has been setup by a student who previously worked on this project, and he always manually turned on the LEDs by entering the Python environment in Linux, and then entering the lines:
import scrollphathd as sphd for y in range(7): for x in range(17): sphd.set_pixel(x,y,1) sphd.show()
after which he could do the required stuff. I want to automate this process, so I can call only one bash file and everything happens for me. So, I create a TurnLightsOn.py file as
#!/usr/bin/env python import scrollphathd as sphd for y in range(7): for x in range(17): sphd.set_pixel(x,y,1) sphd.show()
and converted to an executable by going back to Linux environment and entering
sudo chmod +x TurnLightsOn.py whereafter I can call it using ./TurnLightsOn.py. This then turns on the lights, but immediately switches them off again. How does this happen?
Thanks in advance!
