北京代孕价格一般多少钱【正规代孕生育医疗中心】【微*电138*0226*9370】代孕，是指将受精卵子植入代孕妈妈子宫，由孕母替他人完成“十月怀胎一朝分娩”的过程。妇女代孕时需植入他人的受精卵子，精子与卵子在人体外的结合，必须实施“人类辅助生殖技术”。我国有关法律对“人类辅助生殖技术”的实施做了严格的规定。
由于板子LCD旧屏是ili9335型号的,旧屏有时候会断货,如果断货则使用一个st7789v型号的LCD
它们两个屏的区别在于初始化屏的参数不同,引脚都一样,也就是说需要使板子同时支持ili9335型号和st7789v型号
思路:
- 1.uboot在显示LOG(初始化屏参数)之前,通过命令来读LCD型号,来检测LCD型号,然后来修改初始化屏的参数.
- 2.如果屏是新屏,则设置bootargs,向内核传递参数lcd_type=new
- 3.当kernel收到参数lcd_type=new时,则在初始化LCD之前,修改屏的参数.
改uboot
首先来看单板配置信息,根据配置找到哪个文件是初始化LCD屏的
根据make ap60pro_uImage_sfc_nand命令,找ap60pro_uImage_sfc_nand单板信息
vi ./u-boot/boards.cfg
找到:
# Target ARCH CPU Board name Vendor SoC Options ############################################################## ap60pro_uImage_sfc_nand mips xburst ap60pro ingenic x1000 ap60pro:SPL_SFC_NAND,LIBSLEEP,GET_BT_MAC
从上面看到board name为ap60pro,所以最终通过下面几个来初始化:
./arch/mips/cpu/xburst\x1000\start.S //启动代码 ./include/configs/ap60pro.h //各种define配置 ./board/ingenic/ap60pro //单板配置源文件
查看ap60pro.h,查看LCD相关的define配置
查找CONFIG_ILI9335_240X320,找到在./board/ingenic/ap60pro/Makefile里调用:
COBJS-$(CONFIG_ILI9335_240X320) += lcd-ili9335_240x320.o //保存LCD初始化参数的信息
查找CONFIG_ILI9335_240X320,找到在./drivers/video/Makefile里调用:
COBJS-$(CONFIG_JZ_LCD_V13) += jz_lcd/jz_lcd_v13.o //根据lcd-ili9335_240*320.c来初始化LCD
修改lcd-ili9335_240x320.c
添加st7789v初始化的数组表(在代码中以New_ili9335_data_table数组表示):
struct smart_lcd_data_table ili9335_data_table[] = { //旧屏的初始化参数表

查看jz_lcd_v13.c调用顺序
从uboot启动时,调用board_init_r()函数开始:
-> board_init_r()
-> stdio_init()
-> drv_lcd_init() //初始化硬件LCD
-> drv_video_init() //绘制log
其中drv_lcd_init()中调用顺序为:
-> drv_lcd_init()
-> lcd_init()
-> lcd_ctrl_init() // 位于drivers\video\jz_lcd\Jz_lcd_v13.c
所以,接下来,我们便来修改jz_lcd_v13.c,让uboot在初始化LCD之前,读LCD的ID,是否需要切换新屏参数
修改jz_lcd_v13.c
由于X1000的SLCD控制寄存器只能向LCD写命令/数据，没有读数据的寄存器,所以我们便需要使用GPIO来模拟时序,读出ID来
参考ST7789V数据手册,找到ID命令为04h:
参考ST7789V数据手册,找到读写8080时序图:

}
上面的set_lcd_type_from_cmdline()函数需要在后面调用main_loop()的时候之前被调用,所以还需要修改board_init_r()函数(arch\mips\lib\Board.c ).
然后装上旧屏ili9335,启动uboot,查看读的屏幕ID,屏幕显示正常:
然后换为新屏,启动uboot,查看读的ID信息,log显示正常:
启动内核时,也可以看到传递给内核bootargs有我们新添的参数:
然后在内核中,便通过新参数再次设置屏参数表即可.
