From c2b2278a49a25ec180a9671e3f5a37643a102658 Mon Sep 17 00:00:00 2001 From: vcore85 Date: Tue, 11 Apr 2023 23:43:19 +0800 Subject: [PATCH] tmc5160: add DRV_CONF Register for TMC5160 (#6154) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In some condition ，“drvstrength 2” does not work. According to page 17, some mosfets need “drvstrength” set to 0 . From datasheet rev1.15, the DRVSTRENGTH reset default is 0 .
