Overriding Default LCD 16207 Driver

Here I am again.

I still can't get it to work and have even more questions now.

All makefiles are generated by the IDE, first the makefile in the Debug directory is created; this file says this:

-------------------------------------------------------------------------------------------------# Every subdirectory with source files must be described here

SUBDIRS :=

altera_avalon_lcd_ks0713/HAL/src

# Include the makefiles for each source subdirectory

-include ${patsubst %, %/subdir.mk, $(SUBDIRS)}

MAKEFILE_LIST += $(patsubst %, %/subdir.mk, $(SUBDIRS))

-------------------------------------------------------------------------------------------------

So this is (what I think) what's happening: The auto generated subdir.mk file is included here. This file is located in a subdir of the Debug directory: "altera_avalon_lcd_ks0713/HAL/src". The content of this file is this:

-------------------------------------------------------------------------------------------------

C_SRCS +=

${addprefix altera_avalon_lcd_ks0713/HAL/src/,

altera_avalon_lcd_ks0713.c

}

CXX_SRCS +=

${addprefix altera_avalon_lcd_ks0713/HAL/src/,

}

ASM_SRCS +=

${addprefix altera_avalon_lcd_ks0713/HAL/src/,

}

-------------------------------------------------------------------------------------------------

So now the compiler will compile this file. But when the file is being compiled, it can't locate the associated header files: "altera_avalon_lcd_16207.h" and "altera_avalon_lcd_ks0713_regs.h". It doesn't use the header file I created, but the one provided by altera, and I just can't get it work.

When I take al look at the generated_all.mk file (Located in the system_description directory) a variable called "COMPONENTS_DEVICE_DRIVERS" is made, but with the driver provided by altera located at "/cygdrive/c/eda/altera/quartus60/sopc_builder/components/altera_avalon_lcd_16207" and not with the driver I created.

I've read the instructions from altera in the software developer's handbook several times, and I don't know what I do wrong. I've created a directory called "altera_avalon_lcd_ks0713" in the system library directory, and created the subdirs "HAL/inc", "HAL/src" and "inc". I've created a header file called "altera_avalon_lcd_ks0713_regs.h" in the "inc" subdir. I've created a header file called "altera_avalon_lcd_16207.h" in the "HAL/inc" subdir. And I've created a source file called "altera_acalon_lcd_ks0713.c" in the subdir "HAL/src". I've also changed the names to 16207, but this doesn't matter.

The instructions from altera says that the system library directory is seached first to locate a header file with the corresponding name from the SOPC builders component. And when the IDE found one, it skips the original driver. But this is not what's happening.

I also created the component.mk file in the HAL/src directory with the following contents:

-------------------------------------------------------------------------------------------------

C_LIB_SRCS += altera_avalon_lcd_ks0713.c

INCLUDE_PATH += altera_avalon_lcd_ks0713/inc

-------------------------------------------------------------------------------------------------

I tried various things but I can't get it compiled with the right driver. So I hope someone could give me the right tip.

Please help me, I realy need this to work.

Best regards,

Ronald
