ssdfb.h

${LINUX}/include/linux

Contains IOCTL defines and
others used by ssdfb.c. Should
be included by user applications
to access IOCTL commands.

LCD_SSD1783B.c ${LINUX}/drivers/video

This file contains the low-level
code to communicate with the
SSD1783U2 controller. It must
be linked with the ssdfb.c code
during module compilation.

LCD_SSD1783B.h ${LINUX}/include/linux

This file contains defines and
functional prototypes for all
capabilities of the SSD1783U2
controller.

LPC3180_GPIO.h ${LINUX}/include/linux

This file contains defines for
working with the LPC3180
GPIO pins.

Makefile

${LINUX}/drivers/video

This file has been modified to
include framebuffer support
directly into the linux kernel.
Also, lines were added to
successfully compile ssdfb.c and
link it during the ‘make
modules’ stage of compilation.

lpc3000evb_defconfig ${LINUX}/arch/arm/configs This file contains modifications

to enable framebuffer support
directly in the kernel when
building kernel images.

setup_links

${LINUX}

This file is sourced prior to
cross-compiling the linux kernel
for the ARM architecture. It
specifically sets the
CONFIG_FB_SOLSYS
environment variable to ‘m’ to
compile the ssdfb as a module.

During kernel compilation, it is important to set the following environment variable to
build the framebuffer module with the rest of the kernel:

export CONFIG_FB_SOLSYS=m

If desirable, this command can be placed within the setup_links file within the kernel
root.

Please consult section

14.0

APPENDIX C Framebuffer API

for a detailed list of IOCTL

commands to interact with the framebuffer in a user-space application.
