User guides
A user guide is provided for each set of selected features. These documents will enable the
user to get started with the relevant features. An example code is also included as well as a
troubleshooting section.
A list (non-exhaustive) of existing user guides is given below.
CTV100-LCD: STV3550 user controls user guide
The remote control service is responsible for the byte assembly of infrared frames coming
from a remote control device. It provides the client with a high-level interface to manage
remote control inputs.
The user interface service provides the client with a high-level interface to manage both
remote control and keyboard inputs. The client provides its own code, with which it will be
notified.
CTV100-LCD: STV3550 video and sync user guide
The video service provides the client with a high-level interface for managing the video.
This service is responsible for the complete management of the video buffers and the video
display, according to client configuration, in terms of the video mode (up-conversion,
Proscan...).
It also offers video-related features, such as zoom or freeze frame, among others.
The synchronization service is responsible for programming the field polarity. It provides the
client with a high level interface for managing the field polarity sequences.
CTV100-LCD: STV3550 source selection user guide
The audio/video switch service is responsible for managing the connections between audio
and video inputs and outputs by using drivers that provide audio/video switching functions.
The audio/video switch component is also responsible for detecting changes in the slow
blanking level (available on SCART connections) by using the ADC driver.
The front end service is responsible for the tuning and the scanning operations. It provides
the client with a high level interface working in the frequency domain.
CTV100-LCD: STV3550 graphics user guide
It provides the necessary software for creating cursors and graphic planes using
respectively the Cursor Driver (DV_GAM) and the On-Screen Display Driver (STOSD).
It also includes the Two Dimensional Block Move Driver (DV_BME) in order to improve
graphical applications which often require moving blocks of data.
This document will describe the CTV100-LCD Basic Graphics Stack and also provide a
guide for the implementation and configuration of a graphical user interface (GUI) stack
based on the OSD.
Reference guide
There is one reference guide for each component (service, driver, etc.). This document
includes the API as well as an example of use. This document specifically targets design
engineers.
