From 5e40c336f24bd6f479f13a4b2fd363c9a16356a6 Mon Sep 17 00:00:00 2001 From: resset Date: Sat, 26 Jan 2013 21:53:16 +0100 Subject: [PATCH 01/12] initial commit: copy sources from SSD1289 I started project of new driver: SSD2119. This work is based on SSD1289. I don't know exactly if this one is the most similar to my one. It's just an experiment. There is no accompanying board file of any flavor, but the hardware lying on my desk is Embest DM-STF4BB with DM-LCD35RT LCD module. Changes already made: - Copied entire drivers/gdisp/SSD1289 directory into drivers/gdisp/SSD2119. - Changed every occurrence of "SSD1289" to "SSD2119" in each source file. --- drivers/gdisp/SSD2119/gdisp_lld.c | 583 ++++++++++++++++++ drivers/gdisp/SSD2119/gdisp_lld.mk | 5 + .../gdisp/SSD2119/gdisp_lld_board_example.h | 125 ++++ .../SSD2119/gdisp_lld_board_example_fsmc.h | 164 +++++ .../gdisp_lld_board_firebullstm32f103.h | 157 +++++ drivers/gdisp/SSD2119/gdisp_lld_config.h | 53 ++ drivers/gdisp/SSD2119/readme.txt | 19 + 7 files changed, 1106 insertions(+) create mode 100644 drivers/gdisp/SSD2119/gdisp_lld.c create mode 100644 drivers/gdisp/SSD2119/gdisp_lld.mk create mode 100644 drivers/gdisp/SSD2119/gdisp_lld_board_example.h create mode 100644 drivers/gdisp/SSD2119/gdisp_lld_board_example_fsmc.h create mode 100644 drivers/gdisp/SSD2119/gdisp_lld_board_firebullstm32f103.h create mode 100644 drivers/gdisp/SSD2119/gdisp_lld_config.h create mode 100644 drivers/gdisp/SSD2119/readme.txt diff --git a/drivers/gdisp/SSD2119/gdisp_lld.c b/drivers/gdisp/SSD2119/gdisp_lld.c new file mode 100644 index 00000000..92a13532 --- /dev/null +++ b/drivers/gdisp/SSD2119/gdisp_lld.c @@ -0,0 +1,583 @@ +/* + ChibiOS/GFX - Copyright (C) 2012 + Joel Bodenmann aka Tectu + + This file is part of ChibiOS/GFX. + + ChibiOS/GFX is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 3 of the License, or + (at your option) any later version. + + ChibiOS/GFX is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

No other routines than initialization ones were changed. Properly displays "basics" demo. Main features and changes: - Based on SSD1289 and SSD1121 in FSMC mode. - Uses FSMC module. Maybe oneday I will make GPIO version. - LCD backlight PWM input is tied high (no timer yet). - Added ssd2119.h with SSD2119 registers' addresses. - Updated set_cursor and set_viewport functions. Not thoroughly tested, however. - Rewritten GDISP_LLD(init)(void) function. --- drivers/gdisp/SSD2119/gdisp_lld.c | 170 ++++++++++-------- .../SSD2119/gdisp_lld_board_embest_dmstf4bb.h | 84 +++++---- drivers/gdisp/SSD2119/ssd2119.h | 74 ++++++++ 3 files changed, 213 insertions(+), 115 deletions(-) create mode 100644 drivers/gdisp/SSD2119/ssd2119.h diff --git a/drivers/gdisp/SSD2119/gdisp_lld.c b/drivers/gdisp/SSD2119/gdisp_lld.c index eac72d76..f430d669 100644 --- a/drivers/gdisp/SSD2119/gdisp_lld.c +++ b/drivers/gdisp/SSD2119/gdisp_lld.c @@ -30,6 +30,8 @@ #include "hal.h" #include "gfx.h" +#include "ssd2119.h" + #if GFX_USE_GDISP /*|| defined(__DOXYGEN__)*/ /* Include the emulation code for things we don't support */ @@ -40,10 +42,10 @@ /*===========================================================================*/ #ifndef GDISP_SCREEN_HEIGHT - #define GDISP_SCREEN_HEIGHT 320 + #define GDISP_SCREEN_HEIGHT 240 #endif #ifndef GDISP_SCREEN_WIDTH - #define GDISP_SCREEN_WIDTH 240 + #define GDISP_SCREEN_WIDTH 320 #endif #define GDISP_INITIAL_CONTRAST 50 @@ -56,8 +58,6 @@ #if defined(GDISP_USE_CUSTOM_BOARD) && GDISP_USE_CUSTOM_BOARD /* Include the user supplied board definitions */ #include "gdisp_lld_board.h" -#elif defined(BOARD_FIREBULL_STM32_F103) - #include "gdisp_lld_board_firebullstm32f103.h" #elif defined(BOARD_EMBEST_DMSTF4BB) #include "gdisp_lld_board_embest_dmstf4bb.h" #else @@ -73,26 +73,26 @@ #define delayms(ms) chThdSleepMilliseconds(ms) static __inline void set_cursor(coord_t x, coord_t y) { - /* Reg 0x004E is an 8 bit value - * Reg 0x004F is 9 bit + /* Reg SSD2119_REG_X_RAM_ADDR is 9 bit value + * Reg SSD2119_REG_Y_RAM_ADDR is an 8 bit * Use a bit mask to make sure they are not set too high */ switch(GDISP.Orientation) { case GDISP_ROTATE_180: - write_reg(0x004e, (GDISP_SCREEN_WIDTH-1-x) & 0x00FF);
