I bought a grove led bar and I was wondering which library/code/firmware I could use when I connect it directly to GPIO from raspberry… As far as I found on the internet, this should be possible because it’s a digital sensor. I found code for micropython, but don’t know which GPIO’s I should use and if i could code from <LINK_TEXT text=“https://github.com/mcauser/micropython- … /my9221.py”>https://github.com/mcauser/micropython-my9221/blob/master/my9221.py</LINK_TEXT>
Can someone point me in the right direction?
Thank you. Any advice about connecting it to the GPIO-pins?
Were you able to figure this out? I am trying to figure out how to wire to pins D8 and D9 of the LED bar to a Raspberry Pi and how to talk to it from Linux.
Yes, I used the Grove Base board Grove Base HAT | Seeed Studio Wiki and found example code to use it: https://github.com/zolgear/grove.py/blob/master/grove/grove_ledbar.py
