Honored Contributorhello! i'm trying to download picture.dat to kit DE1 using Control panel. And i want to process that image in SRAM. But i don't know about picture.dat format. Can anybody explain about that problem!:confused: thanks so much!
Honored Contributormy problem is same. When i try to read DE1_USB_API project i see these line
assign mVIN_R = mVGA_ADDR[0] ? mSRAM_VGA_DATA[15:8]<<2 : mSRAM_VGA_DATA[7:0]<<2 ; assign mVIN_G = mVGA_ADDR[0] ? mSRAM_VGA_DATA[15:8]<<2 : mSRAM_VGA_DATA[7:0]<<2 ; assign mVIN_B = mVGA_ADDR[0] ? mSRAM_VGA_DATA[15:8]<<2 : mSRAM_VGA_DATA[7:0]<<2 ; i don't understand that code "<<2" because vga data only take 4 MSB bit assign VGA_R = oVGA_R[9:6]; assign VGA_G = oVGA_G[9:6]; assign VGA_B = oVGA_B[9:6]; please help me. thanks in advance
