Using a Computer for Control and Programming
Instructions for Bitmap Picture Download:
The bit map download function in VGM allows you to display, using the video generator, an image stored as a BMP file by your computer. The bit map is transferred directly to the video memory and the color information in the file is transferred directly to the color lookup table memory. Selecting another test image or video format will clear the displayed
NOTE: The bit map download operation does not clear the current displayed test image. It will only over write the portion of active video that matches the size and offset of the downloaded image. The download operation will modify the color lookup table values. This may cause the color to change on other portions of the screen. If you want to start with a blank screen, you should first display the “raster” test image.
1. Requirements to download a bit mapped image file to a generator:
-The target generator firmware must support the bit map download function.
-The bit mapped image file must be stored on the computer as an uncompressed .BMP file.
-VGM must have communications open with the target generator
2.Select Tools
3.Select the target generator from the pull- down ”Select a Generator” list. The active video dimensions (in pixels) of the current video format being produced by the genera- tor will be shown in the Screen Dimensions” area of the Image Download screen.
4.You must check the "Serial Option / Use Ymodem" check box when downloading the
image via a serial port connection. If you do not put a check in the box, the software will attempt to use a USB connection for the download. The software may stop responding if the box is not checked and there is no USB connection to the generator.
