Subject: [PATCH] overlays: mpu6050: Add 'addr' parameter
|
|
|
|
The mpu6050 starts up at address 0x68 by default, but can be set to
|
|
0x69 if the ADO pin is pulled high. Give the overlay an addr parameter
|
|
to allow devices at the alternate address to be used.
|
|
|
|
See: https://github.com/Hexxeh/rpi-firmware/issues/252
