get Minigui3

from http://www.minigui.org/en/download/ Here to download The following three files ：

 

libminigui-gpl-3.0.12.tar.gz MiniGUi3 The library of

minigui-res-be-3.0.12.tar.gz Minigui3 Resource files for

The first two files are required

mg-samples-3.0.12.tar.gz Minigui3 An example of

 

Extract it in one place , For example, my catalog is : /code/code_2016/mingui3

 

compile Minigui3

Minigui3 Very small , It's really small , and QT For enterprise applications , It's easy to compile , It'll be over in a few minutes , Think about compiling QT Hour two , Three hours is terrible , From time to time, I also report mistakes to you , It's really Mini, and UcGUI Just as small , The implementation principle is basically the same , But it is enough for most of us to do general applications , But on a particular platform , Use it well , Make beautiful and efficient UI, I really want to be in these small GUI Customize and modify a lot of things by yourself .

         I basically compile by default MiniGui3 Of .

      Compile the basic library

Unzip the file

tar –zxvf libminigui-gpl-3.0.12.tar.gz

         cdlibminigui-gpl-3.0.12

Get into MiniGUI3 In the directory , There will be one build The catalog of , Compile scripts for many platforms already exist , There is no Hess , In fact, the matching is also very simple . Before transplantation, you should know Migui3 Of GAL and IAL, Basically, these two parts are what we do , Where it is , If you haven't used it , It is also difficult for us to modify it .

         GAL yes UI Drawing interface ,IAL It is the interface of external equipment , Open a few files to learn , Basically, I understand , Just a few struct Interface , Different platforms are basically the same .

         Because with Linux framebuffer Standard interface , Few changes have been made .

         Write a configuration script file in the root directory , Such as , The following two configurations 3520d and 3531 It's basically the same :

         #forhi3520D

CFLAGS="-I/home/jhting/minigui3/include-g -O0" ./configure \

         --host=arm-hisiv100nptl-linux  \

         --prefix=/board/minigui3/hi3520d/\

         --disable-screensaver\

         --disable-splash\

         --disable-jpgsupport    \

         --enable-videoqvfb=no\

       --enable-rtosxvfb=no \

       --enable-pcxvfb=no

 

         #forhi3531

CFLAGS="-I/home/jhting/minigui3/include-g -O0" ./configure \

         --host=arm-hisiv100nptl-linux  \

         --prefix=/board/minigui3/hi3531/\

         --disable-screensaver\

         --disable-splash\

         --disable-jpgsupport    \

         --enable-videoqvfb=no\

       --enable-rtosxvfb=no \

       --enable-pcxvfb=no

        

Not used qvfb So turn them off （ An error containing the header file will also be reported when opening , But the corresponding changes Makefile Just fine ）.

Execute the script above

Again :

make install

 

So after compiling , No report error , More fortunate .

 

Compile and install resource files

Resource files only need ./configure Connect it inside –prefix and –host Just install it , Basically :

./configure --host=arm-hisiv100nptl-linux  --prefix=/board/minigui3/hi3531/

Compile the sample program

         Example program I didn't compile all , I compiled whichever I used , Such as ：

#for hi3520D

arm-hisiv100nptl-linux-gcc -o helloworldhelloworld.c -I/board/minigui3/hi3520d/include -L/board/minigui3/hi3520d/lib-L/code/code_2016/mingui3/hisi_hifb/board/hi3520d/lib -I/code/code_2016/mingui3/hisi_hifb/board/hi3520d/include-static  -lminigui_ths -lhifb -lmpi  -laec -lhdmi -lmem -ltde -ljpeg -lVoiceEngine-lresampler -lanr -lvqev2 -ljpeg6b -lpthread -lm -lpthread –ldl

 

#for hi3531

arm-hisiv100nptl-linux-gcc -o helloworldhelloworld.c  -I/board/minigui3/hi3531/include/-L/board/minigui3/hi3531/lib-L/code/code_2016/mingui3/hisi_hifb/board/hi3531/lib-I/code/code_2016/mingui3/hisi_hifb/board/hi3531/include -static  -lminigui_ths -lhifb -lmpi  -laec -lhdmi -lmem -ltde -ljpeg -lVoiceEngine-lresampler -lanr -lpciv -lvqev2 -ljpeg6b -lpthread -lm -lpthread –ldl

There is one in the sample program libhifb.a The library of , This is for , Initialize the... Of the Hisilicon platform , There are instructions in the code modification

Code changes

Just press the above , Of course, nothing can come out , That is, when running the program , When compiling the sample program, we have a libhifb.a The library of , This is used to initialize the Hisilicon platform , To initialize Hisilicon MPI Systems and VO Output , Set some necessary parameters , In this part, I made a separate library for it , In this way MiniGUI Add some necessary calls libhifb.a This library , The modifications on different Hisilicon chip platforms are libhifb.a This library is finished , This won't put UI The code is too messy .

Initialize the code of Hisilicon

We use it Minigui3 Inside fbcon Interface to interface with Hisilicon fb Interface , to glance at minigui3 Inside fbcon Interface , Basic implementation sysvideo.h Inside GAL_VideoDevice The method of structure is OK ,fbcon Inside fbvideo.c It's all done , What we need to do is to connect with the Shanghai think platform hifb Just OK, Only a few lines have been changed .

The basic idea is to GAL_VideoDevice There are also initialization operations in , Put Hayes mpp,vo The initialization of is put here , There is one SetVideoMode Set the operation handle hifb Just put the parameters of .

For convenience , stay fbvideo.c To define a HISI_FB The macro , Use it to control the code modification relative to the Hisilicon platform .

So according to the basic needs , Define a header file hisi_hifb.h, Define the following methods :

 

int HIFB_VO_Start(void);

int HIFB_VO_Stop(void);

 

int HIFB_SetVideoMode(int fd, int width, int height, int bpp, intflags);

 

These methods are in libhifb.a A library implementation of .Minigui3 As long as fbvideo.c Just call it at the right place in the .

 

Write a libhifb.a The engineering of , Its directory is like this

Board The directory includes different platform header files and lib

There are codes of different platforms in the same level directory Such as src_hi3520d/src_hi3531/src_hi3536

However, Hisilicon has different platforms hifb and tde Basically consistent , It can also be written in the same code , There's no need to be so detailed .

There is a in the root directory Makefile.param The contents are as follows :

exportBOARD?=hi3531

exportINSTALL_PREFIX?=/board/minigui3/$(BOARD)

 

exportLIBTARGET?=libhifb.a

exportCROSS_COMPILE?= arm-hisiv100nptl-linux-

export CROSS?=arm-hisiv100nptl-linux-

 

exportCC:=$(CROSS)gcc

exportAR:=$(CROSS)ar

 

export CFLAGS +=-g -O0 -Wall -Werror

 

ifeq($(HIARCH),hi3531)

CFLAGS +=-march=armv7-a -mcpu=cortex-a9 -mfloat-abi=softfp -mfpu=vfpv3-d16

CXXFlAGS+=-march=armv7-a -mcpu=cortex-a9 -mfloat-abi=softfp -mfpu=vfpv3-d16

endif

 

exportPWD_PATH?=/code/code_2016/mingui3/hisi_hifb

 

exportMPP_LIB?=$(PWD_PATH)/board/$(BOARD)/lib

exportMPP_INCLUDE?=$(PWD_PATH)/board/$(BOARD)/include

 

CFLAGS +=-I$(MPP_INCLUDE)

 

If you compile , Modify the inside BOARD Parameters , Of course, it may be more convenient to pass it in as a parameter .

 

There is one in the catalog of different chips Makefile, It's all the same :

include../Makefile.param

 

SRC  := $(wildcard *.c)

OBJ  := $(SRC:%.c=%.o)

        

all:$(OBJ)

         $(AR) rv $(LIBTARGET) $(OBJ)

         cp $(LIBTARGET) $(INSTALL_PREFIX)/lib/

         cp hisi_hifb.h$(INSTALL_PREFIX)/include/

 

%.o:%.c

         $(CC) $(CFLAGS) -c $< -o [email protected]

        

.PHONY:clean 

clean:

         @rm -f $(OBJ)

 

In the code, I use , The operation is that I directly put Hess mpp Inside sample Copy the code , Such as src_hi3531 Files in :

 

Just change a little bit ！

 

Connect the above things , Implemented a libhifb.a Library to initialize Hisilicon's stuff , stay Minigui3 Inside fbcon Inside fbvideo.c Call the appropriate place in the OK, Basically that's it , Make up again Minigui3 Library and helloworld Program , Just run .

 

Configure to run

         The configuration will be modified a little , hold GAL Designated as fbcon, The resolution is changed ,IAL Just point to the corresponding mouse .

Some of the problems

1: In the process of doing the above , One of the problems is , Press the above thing , stay hi3515/hi3520D Up is running is OK 了 , Can output , But in hi3531,hi3536 Run up , Dead or alive, no output , After a day's work, there was no result , The final discovery is fbcon Some others in ioctl After the operation ,hi3531/hi3536 Of fb No way. , Closed some ioctl The operation is OK 了 .

         2: The mouse has a shadow , This was used before ucgui Sometimes there are , It seems that it is better to use the mouse layer of Hisilicon to realize .

 

Basically, that's all , If you want to achieve good , Still have to use hifb Inside TDE These things , Otherwise, the picture will not work , The big screen must .

It's too late , If there is a hole in the document , Only dig but not fill , Identify yourself ！！！ For reference only ！！！
