Wind River UGL v1.2 Display Drivers
The Wind River UGL v1.2 display drivers for the S1D13706 Embedded Memory LCD
Controller are intended as “reference” source code for OEMs developing for Wind River’s
UGL v1.2. The drivers provide support for both 8 and 16 bit-per-pixel color depths. The
source code is written for portability and contains functionality for most features of the
S1D13706. Source code modification is required to provide a smaller, more efficient driver
for mass production.
The UGL display drivers are designed around a common configuration include file called
mode0.h which is generated by the configuration utility 13706CFG. This design allows for
easy customization of display type, clocks, addresses, rotation, etc. by OEMs. For further
information on 13706CFG, see the 13706CFG Configuration Program User Manual,
document number X31B-B-001-xx.
This document and the source code for the UGL display drivers are updated as appropriate.
