1. LCD
1.1怎样新建一个LCD驱动
LCD模组主要包括LCD显示屏和驱动IC。比如LF040DNYB16a模组的驱动IC型号为NT35510。要在MTA5573平台上新建这个lcd的驱动,步骤如下:
A. 新建文件夹nt35510:
\mediatek\custom\common\uboot\lcm\ nt35510
\mediatek\custom\common\kernel\lcm\ nt35510
\mediatek\custom\common\lk\lcm\ nt35510//JB ADD
B.修改\mediatek\custom\common\kernel\lcm\ mt65xx_lcm_list.c, 在lcm_driver_list [ lcm_count ] 中增加nt35510_lcm_drv。
C.打开mediatek\config\ginwave73_gb\ProjectConfig.mk:
BUILD_LK=yes //JB ADD
BUILD_UBOOT=yes
BOOT_LOGO=wsvganl
CUSTOM_UBOOT_LCM = nt35510
CUSTOM_KERNEL_LCM = nt35510
CUSTOM_LK_LCM= nt35510//JB ADD
LCM_WIDTH=
LCM_HEIGHT=
1.2 LCDIC nt35510.c驱动文件移植原则:
根据具体平台,填充对应的函数,不能直接复制整个文件,避免不必要编译和接口错误。
1.3 LCD旋转180度(默认竖屏方向,关联到很多界面,需要统一修改)
Driver:MTK_LCM_PHYSICAL_ROTATION =180//驱动层此种改法影响camera\tp\sensor及其他功能。(不推荐此方法)
MMI:PhoneWindowManager.java中修改。(此方法会引起其他MMI问题) (不推荐此方法)
Feature:(横屏竖屏替换)LCM_WIDTH= LCM_HEIGHT=
2. leds 配置
CUSTOM_KERNEL_LEDS= mt65xx
mediatek\custom\a5\kernel\leds\mt65xx\cust_leds.c
mediatek\custom\a5\uboot\cust_leds.c
static structcust_mt65xx_led cust_led_list[MT65XX_LED_TYPE_TOTAL] = {

6.4 FUEL GAUGE 电池电量检测方法及原理(备注)
随着大容量电池的使用,如果设备能够精确的了解电池的电量,不仅能够很好地保护了电池,防止其过放电,同时也能够让用户精确地知道剩余电量来估算所能使用的时间,及时地保存重要数据。电池电量的检测有三种种不同电量计的实现方法,

6.5 MTK Android 充电概念
目前充电主要包括Power Off Charging(关机充电) 、IPO Charging(假关机充电)和 OS Charging(开机充电) 三个部分
1),Power Off Charging 部分,可以仔细阅读如下部分的code:
alps\mediatek\platform\mt6575\uboot\mt6575_bat.c // Power Off Charging 的控制流程, 建议从函数mt65xx_bat_init() 开始看code
alps\mediatek\custom\[project]\uboot\inc\cust_battery.h // Power off Charging的一些充电参数的配置
2),OS charging部分,可以仔细阅读如下部分的code:
alps\mediatek\platform\mt6575\kernel\drivers\power\mt6575_battery.c // OS Charging 的控制流程, 建议从函数BAT_thread()开始看
alps\mediatek\custom\[project]\kernel\battery\battery\cust_battery.h // OS Charging的一些充电参数的配置
建议将alps\mediatek\platform\mt6575\kernel\drivers\power\ 目录下的所有文件都仔细阅读一遍
3), IPO Charging部分实际使用的还是OSCharging部分的code,IPO可以参考 alps\mediatek\source\external\ipod\ 目录下的相关文件

28.SIM卡
SIM卡模块存放在modem大的模块中,配置方法参照MTK feature phone。
28.1 simcard热插拔功能
\surplus77\modem\make\SURPLUS_HSPA.mak
SIM_HOT_SWAP= NONE
29.SD卡
27.1热插拔功能
1,sd卡热插拔机制的实现需要软件和硬件同时配合才能实现。
2,在电路上,需要一根单独的检测pin脚,通过检测pin脚的高低电平来检测sd卡的插拔动作,并在dws中将其配置成上拉或下拉
3,软件上的配置主要就是在\mediatek\custom\
4,如果是低电平触发,将msdc1_hw中的.cd_level 设置成 MSDC_CD_LOW,否则设置成MSDC_CD_HIGH
备注:
(1),从hardware的角度,sd 卡槽中的CD 引脚与chip的EINT的某个脚连在一起,且chip内部会有上拉电阻。
(2),dct的配置如下:
注:EINT16使用的哪个GPIO,可以参考硬件hw_config.xls文档
