I am trying to use the grovepi + shield with RPI4. I followed the instructions on the website (https://wiki.seeedstudio.com/GrovePi_Plus/). The installation was successful but when I run the command sudo i2cdetect -y 1
I get this result:
0 1 2 3 4 5 6 7 8 9 a b c d e f
00: - - - - - - - - - - - - -
10: - - - - - - - - - - - - - - - -
20: - - - - - - - - - - - - - - - -
30: - - - - - - - - - - - - - - - -
40: - - - - - - - - - - - - - - - -
50: - - - - - - - - - - - - - - - -
60: - - - - - - - - - - - - - - - -
70: - - - - - - - -
Do you have any ideas why I can’t communicate with the shield?
Thanks
