Hi
I have a question , please to help.
HardWare : I have LED matrix (100 LED ( width) X 100 LED (height))
SoftWare: on hard disk I have many random size colored images files and using vb.net I’m able to converted any of these images into an image file of black and white pixels only - why ? in order to send this image into the LED matrix, the final image size after conversion is always ( 100 pixel width X 100 pixel height), I did image processing to convert any image on harddisk into 100 pixel X 100 pixel to send it to the LED matrix.
what I need to do is to send this image file of black and white dots into the corresponding LED and make this image scroll down on the LED matrix. for example pixel (0,0) should be sent to LED(0,0) and make it ON -if pixel is WHITE or OFF-if pixel is BLACK, pixel(1,0) should be sent to LED(1,0) until I reach pixel ( 100,100) should be sent to LED(100,100)
I need a method either parallel or serial to send these pixels(either black which is 0 or white which is 1 ) to its corresponding LED to make it ON or OFF , also I need to crawl down the image , what I mean I need this image to move from up of the LED matrix and crawl down to the end of the LED matrix.
I have uploaded some images for explanation.
1-how I can do the interface , parallel or serial ?
2- how I can control the speed of crawling ?
3-i need a fast interface method ( the rastering should be very fast )
would you please give ideas .
Thanks a lot
