From a272a15bcf1f9dec5f7999e2e4b849aebb91237f Mon Sep 17 00:00:00 2001 From: Brent Perteet Date: Sun, 16 Nov 2025 21:53:32 -0600 Subject: [PATCH] Improve calibration and volume menu UX MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Add calibration submenu with three options: Cancel (default), Calibrate, and Clear - Cancel returns to main menu to prevent accidental calibration - Calibrate runs system_setZeroAngle() and displays "Calibrated" confirmation - Clear runs system_clearZeroAngle() and displays "Cleared" confirmation - Use LVGL timer for non-blocking 1-second confirmation messages - Center confirmation messages both horizontally and vertically - Use larger font (montserrat_16) for better readability - Remove "Back" button from volume control page - Center volume control elements vertically on screen - Improve overall menu navigation and visual consistency 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- main/gui.c | 528 +++++++++++++++++++++++++++++++++++++---------------- 1 file changed, 366 insertions(+), 162 deletions(-) diff --git a/main/gui.c b/main/gui.c index 597d36c..2812ce0 100644 --- a/main/gui.c +++ b/main/gui.c @@ -72,6 +72,9 @@ static lv_obj_t* create_volume_page(void);
