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?
You can try the intel upm library and see if any good news. Hope it helps.
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.
