From 8061822f0cba9caa9d957b85a8284ab3120aaf3e Mon Sep 17 00:00:00 2001 From: Riku Isokoski Date: Tue, 26 Apr 2022 13:09:30 +0300 Subject: Fix large blacklevel step. Lower 25% of shades are now accessible. There is a large step in brightness from level zero to level one. After experimenting with various ST7789 options, I found that decreasing VDV to 0x10 (-0.4V) fixes this issue. The gamma change reduced the average error in brightness, but with the underlying issue fixed, the gamma change has been reverted. --- src/displayapp/screens/Tile.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src/displayapp/screens/Tile.cpp') diff --git a/src/displayapp/screens/Tile.cpp b/src/displayapp/screens/Tile.cpp index 0a113e3e..2d61b1dc 100644 --- a/src/displayapp/screens/Tile.cpp +++ b/src/displayapp/screens/Tile.cpp @@ -87,9 +87,9 @@ Tile::Tile(uint8_t screenID, lv_obj_align(btnm1, NULL, LV_ALIGN_CENTER, 0, 10); lv_obj_set_style_local_radius(btnm1, LV_BTNMATRIX_PART_BTN, LV_STATE_DEFAULT, 20); - lv_obj_set_style_local_bg_opa(btnm1, LV_BTNMATRIX_PART_BTN, LV_STATE_DEFAULT, LV_OPA_40); + lv_obj_set_style_local_bg_opa(btnm1, LV_BTNMATRIX_PART_BTN, LV_STATE_DEFAULT, LV_OPA_50); lv_obj_set_style_local_bg_color(btnm1, LV_BTNMATRIX_PART_BTN, LV_STATE_DEFAULT, LV_COLOR_AQUA); - lv_obj_set_style_local_bg_opa(btnm1, LV_BTNMATRIX_PART_BTN, LV_STATE_DISABLED, LV_OPA_40); + lv_obj_set_style_local_bg_opa(btnm1, LV_BTNMATRIX_PART_BTN, LV_STATE_DISABLED, LV_OPA_50); lv_obj_set_style_local_bg_color(btnm1, LV_BTNMATRIX_PART_BTN, LV_STATE_DISABLED, lv_color_hex(0x111111)); lv_obj_set_style_local_pad_all(btnm1, LV_BTNMATRIX_PART_BG, LV_STATE_DEFAULT, 0); lv_obj_set_style_local_pad_inner(btnm1, LV_BTNMATRIX_PART_BG, LV_STATE_DEFAULT, 10); -- cgit v1.2.3-70-g09d2
