主要是如何制作有颜色的按钮,这样可以使界面更加好看

README for Picturebrowser ========================= The modified files are included as listed in the final report: -alt_ypes.h : header file for io.h -nxview.c: modified this existing, to time the running time of the display -picturebrowser.c: file which handles the logic of buttoons and the driver (button) -hardware (folder): find the project inside and install on the board -jddctmgr.c : modified manager -jdidcint.c: hardware assisted idct transform -Makefile: to compile picturebrowser (you will have to include in romfs to run our project) -io.h -zImage Running our picture viewer: -------------------------- open the project (in hardware folder) with quartus and in programmer install on the board. In the terminal: $ nio2-download -g zImage and the start nios2-terminal $ nios2-terminal at Boot, it detects the USB and run ./pictureviewer Navigate through buttons...enjoy it with moderation:) -README for Picturebrowser ====
