From 552f8d81b9bff8010b328ee944d50830cfcaea5c Mon Sep 17 00:00:00 2001 From: Ted M Lin Date: Mon, 2 Mar 2020 18:43:18 -0500 Subject: Reduce PROGMEM usage for sendstring LUT (#8109) * Reduce PROGMEM usage for keycode map Bit-pack the keycode bool array to gain back a small amount of flash space. The trade-off is an increase in runtime instructions when running macros. It does make the code a bit harder to read, as well as maintain. For configs that use send_string() et al, it saves ~100 bytes. * Switch to macro and common definition Rewrite the array declarations so both the unpacked (original) and packed LUT arrays can use the same value definitions. This is done by defining a macro that "knows what to do". This makes the code much easier to read and maintain. * Fix macro typos and improve perf Pack the bits in a more efficient order for extraction. And also fix the copy/paste error in the macro... * Switch fully to packed LUT Some minor reformatting. Compile tested all sendstring_xyz.h to make sure they were converted properly. Also checked that an unconverted version would generate a compile error. * Apply whitespace suggestions from code review Co-Authored-By: Ryan Co-authored-by: Ryan --- quantum/keymap_extras/sendstring_danish.h | 69 ++++++++++++++++--------------- 1 file changed, 35 insertions(+), 34 deletions(-) (limited to 'quantum/keymap_extras/sendstring_danish.h') diff --git a/quantum/keymap_extras/sendstring_danish.h b/quantum/keymap_extras/sendstring_danish.h index 3505a076b..43b6a56cf 100644 --- a/quantum/keymap_extras/sendstring_danish.h +++ b/quantum/keymap_extras/sendstring_danish.h @@ -19,47 +19,48 @@ #pragma once #include "keymap_danish.h" +#include "quantum.h" // clang-format off -const bool ascii_to_shift_lut[128] PROGMEM = { - 0, 0, 0, 0, 0, 0, 0, 0, - 0, 0, 0, 0, 0, 0, 0, 0, - 0, 0, 0, 0, 0, 0, 0, 0, - 0, 0, 0, 0, 0, 0, 0, 0, +const uint8_t ascii_to_shift_lut[16] PROGMEM = { + KCLUT_ENTRY(0, 0, 0, 0, 0, 0, 0, 0), + KCLUT_ENTRY(0, 0, 0, 0, 0, 0, 0, 0), + KCLUT_ENTRY(0, 0, 0, 0, 0, 0, 0, 0), + KCLUT_ENTRY(0, 0, 0, 0, 0, 0, 0, 0), - 0, 1, 1, 1, 0, 1, 1, 0, - 1, 1, 1, 0, 0, 0, 0, 1, - 0, 0, 0, 0, 0, 0, 0, 0, - 0, 0, 1, 1, 0, 1, 1, 1, - 0, 1, 1, 1, 1, 1, 1, 1, - 1, 1, 1, 1, 1, 1, 1, 1, - 1, 1, 1, 1, 1, 1, 1, 1, - 1, 1, 1, 0, 0, 0, 1, 1, - 1, 0, 0, 0, 0, 0, 0, 0, - 0, 0, 0, 0, 0, 0, 0, 0, - 0, 0, 0, 0, 0, 0, 0, 0, - 0, 0, 0, 0, 0, 0, 0, 0 + KCLUT_ENTRY(0, 1, 1, 1, 0, 1, 1, 0), + KCLUT_ENTRY(1, 1, 1, 0, 0, 0, 0, 1), + KCLUT_ENTRY(0, 0, 0, 0, 0, 0, 0, 0), + KCLUT_ENTRY(0, 0, 1, 1, 0, 1, 1, 1), + KCLUT_ENTRY(0, 1, 1, 1, 1, 1, 1, 1), + KCLUT_ENTRY(1, 1, 1, 1, 1, 1, 1, 1), + KCLUT_ENTRY(1, 1, 1, 1, 1, 1, 1, 1), + KCLUT_ENTRY(1, 1, 1, 0, 0, 0, 1, 1), + KCLUT_ENTRY(1, 0, 0, 0, 0, 0, 0, 0), + KCLUT_ENTRY(0, 0, 0, 0, 0, 0, 0, 0), + KCLUT_ENTRY(0, 0, 0, 0, 0, 0, 0, 0), + KCLUT_ENTRY(0, 0, 0, 0, 0, 0, 0, 0), }; -const bool ascii_to_altgr_lut[128] PROGMEM = { - 0, 0, 0, 0, 0, 0, 0, 0, - 0, 0, 0, 0, 0, 0, 0, 0, - 0, 0, 0, 0, 0, 0, 0, 0, - 0, 0, 0, 0, 0, 0, 0, 0, +const uint8_t ascii_to_altgr_lut[16] PROGMEM = { + KCLUT_ENTRY(0, 0, 0, 0, 0, 0, 0, 0), + KCLUT_ENTRY(0, 0, 0, 0, 0, 0, 0, 0), + KCLUT_ENTRY(0, 0, 0, 0, 0, 0, 0, 0), + KCLUT_ENTRY(0, 0, 0, 0, 0, 0, 0, 0), - 0, 0, 0, 0, 1, 0, 0, 0, - 0, 0, 0, 0, 0, 0, 0, 0, - 0, 0, 0, 0, 0, 0, 0, 0, - 0, 0, 0, 0, 0, 0, 0, 0, - 1, 0, 0, 0, 0, 0, 0, 0, - 0, 0, 0, 0, 0, 0, 0, 0, - 0, 0, 0, 0, 0, 0, 0, 0, - 0, 0, 0, 1, 1, 1, 0, 0, - 0, 0, 0, 0, 0, 0, 0, 0, - 0, 0, 0, 0, 0, 0, 0, 0, - 0, 0, 0, 0, 0, 0, 0, 0, - 0, 0, 0, 1, 1, 1, 1, 0 + KCLUT_ENTRY(0, 0, 0, 0, 1, 0, 0, 0), + KCLUT_ENTRY(0, 0, 0, 0, 0, 0, 0, 0), + KCLUT_ENTRY(0, 0, 0, 0, 0, 0, 0, 0), + KCLUT_ENTRY(0, 0, 0, 0, 0, 0, 0, 0), + KCLUT_ENTRY(1, 0, 0, 0, 0, 0, 0, 0), + KCLUT_ENTRY(0, 0, 0, 0, 0, 0, 0, 0), + KCLUT_ENTRY(0, 0, 0, 0, 0, 0, 0, 0), + KCLUT_ENTRY(0, 0, 0, 1, 1, 1, 0, 0), + KCLUT_ENTRY(0, 0, 0, 0, 0, 0, 0, 0), + KCLUT_ENTRY(0, 0, 0, 0, 0, 0, 0, 0), + KCLUT_ENTRY(0, 0, 0, 0, 0, 0, 0, 0), + KCLUT_ENTRY(0, 0, 0, 1, 1, 1, 1, 0), }; const uint8_t ascii_to_keycode_lut[128] PROGMEM = { -- cgit v1.2.3
