From 8961dac970ce9de35d2a14008184d815ee62e64c Mon Sep 17 00:00:00 2001 From: =?utf8?q?Andreas=20Bie=C3=9Fmann?= Date: Tue, 10 Nov 2015 20:53:17 +0100 Subject: [PATCH] tricorder: rewrite tricordereeprom command MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This rewrite uses lately promoted eeprom_init(int) function to choose the right I2C bus when writing data to the EEPROM.
