Building the Photon v2.0 Display Driver

The following steps build the Photon v2.0 display driver and integrate it into the QNX operating system. These instructions assume the QNX developer environment is correctly installed and the developer is familiar with building for the QNX operating system.

Unpack the Graphics Driver Development Kit Archive

1.Install the QNX ddk package using the Package Manager utility.

For information about the Drivers Development Kit contact QNX directly.

2.Once the ddk package is installed, copy the directory tree /usr/src/gddk_v1.0 into the Project directory.

3.Change directory to Project/gddk_1.0/devg.

4.Unpack the display driver files using the commands:

#gunzip S1D13705.tar.gz

#tar –xvf S1D13705.tar

This unpacks the files into the directory Project/gddk_1.0/devg/S1D13705.

Configure the Driver

The file s1d13705_8.h contains register values required to set the screen resolution, color depth (bpp), display type, etc. The s1d13705.h file included with the drivers may not contain applicable values and must be regenerated. The configuration program 13705CFG can be used to build new s1d13705_8.h files.

Note

S1d13705.h should be created using the configuration utility 13705CFG. For more in- formation on 13705CFG, see the 13705CFG Configuration Program User Manual, document number X27A-B-001-xx available at www.erd.epson.com.

Build the Driver

The first time the driver is built, the following command ensures that all drivers and required libraries are built. At the root of the Project source tree, type make.

Note

To build drivers for X86 NTO type ‘OSLIST=nto CPULIST=x86 make’.

Further builds do not require all libraries to be re-built. To build only the S1D13705 display driver, change to the directory gddk_1.0/devg/S1D13705 and type make.
