From 3e0ea72cab201faea51f8cdb490562151a3f01fd Mon Sep 17 00:00:00 2001 From: Phil Elwell Date: Tue, 15 Dec 2020 17:02:17 +0000 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.
