A new command, SAA7115_DETECT_LOCK_STATUS is added. - Removed the call to powerdown SAA7115 in the SAA7115_close function. - Added support for QVGA mode (320 x 240). - Corrected the size of SIF to 352 x 240(was 320 x 240). - Fixed a bug in switching between inputs of SAA7115. The previous code can only switch inputs of the SAA7115 attached to VP0. * SAA7105.c - Modified the OSD configuration code in SAA7105.c so that it does not overwrite the previous configurations that may be used by other drivers, such as the UART driver. * VPORTCAP.c - Added support for re-configuring the video port and EDMA w/o requiring first close the channel and then open it again. - A bug is fixed related to the use of Video port global interrupt call-back function. Previously call-back works only for VP0. - Added support for automatic detection and correction of field inversion, caused by disconnection & reconnection of video source. This is in function _autoSync(). * VPORTDIS.c - A bug is fixed related to the use of Video port global interrupt call-back function. Previously call-back works only for VP0. * _VPORT.h - Added THREE new fields: numTotalLinesFld1, interlaced and autoSyncEnable in the definition of _VPORT_ChanObj to support automatic detection and correction of field inversion. * FVID.h - Fixed a typo in the definition of the FVID_delete macro. * VPORTCAP.h - Corrected the definition of VPORTCAP_EAV_V0 and VPORTCAP_EAV_V1, they were swapped in last release. - Added a field in the VPORTCAP_Params structure for the application to specify whether automatic field inversion detection and correction mode is enabled. * SAA7115.h - Added definition of a new command: SAA7115_DETECT_LOCK_STATUS - Added the definition of SAA7115_AMuxingMode. - Added SAA7115_MODE_QVGA in the definition of SAA7115_Mode. USAGE ----- This device driver is a mini driver for VideoPort peripheral on TMS320DM***2 chips. It uses EDMA to do the data transfers. This driver supports Video Capture & Video Display. It supports BT656 & YC mode for capture. And it supports BT656, YC and Raw mode for display. It does not support TSI or Raw mode for capture. FILES ----- - vportcap.c: Implementation of capture driver. - vportdis.c: Implementation of display driver. - saa7115.c: Implementation of saa7115 video decoder configuration through I2C. - saa7105.c: Implementation of saa7105 video encoder configuration through I2C. - _saa7105.c: configuration tables for saa7105. - _saa7115.c: configuration tables for saa7115. _ _iic.c: _IIC_write function. NOTES ----- - Files in the library are compiled with "no optimization switch" turned on, and the same is true for the project files. If you plan to use this module in a project release, you should rebuild the library with optimization turned on. Known Problems At Release ------------------------- - None. Q&A --- Q1: Where can I find the documentation for writing IOM drivers? Q1: Where can I find the documentation for writing IOM drivers? A1: The literature number is SPRU616, DSP/BIOS Device Driver Developer's Guide.
