- regs4740.h: macros to access selected Jz4740 registers
- ubb-vga2.c: replaced all pointers to registers with access macros
- ubb-vga2.c (line_cycles): we now seem to be 0.1 us slower
- ubb-vga2.c (line): write the first word to the TX FIFO after starting
the command or it is lost
- ubb-vga2.c (line): fetch the first word while waiting for the back
porch, making sure we have plenty of time for cache effects
- ubb-vga2.c (line): we no longer need to prefetch the first word of
the next line
- ubb-vga.h (ccube_init, ccube_map), ccube.c: color mapper based on
proximity in color cube
- grabfb.c (pattern, grabfb), ppmimg.c (pattern, convert): use the color
cube mapper instead of inferios threshold-based mapping
- ubb-vga2.c (session): initialize the color cube
- ubb-vga.h (thres), grabfb.c (thres), ubb-vga2.c (usage, main): removed
the threshold along with the option (-l) to set it
- Makefile (OBJS): added ccube.o
- Makefile (OBJS): added ppm.o and ppmimg.o
- ppm.h (load_ppm), ppm.c: PPM file loader, adapted from
eda-tools/schhist/ppmdiff/ppmdiff.c
- ubb-vga.h (img_name, ppmimg), ppmimg.c: PPM image to frame buffer
converter
- ubb-vga2.c (usage, main): the threshold is now set with the option -l
- ubb-vga2.c (usage, main): if a second argument is given, treat it as
a PPM file
- ubb-vga2.c (usage): also documented option -t
- tstimg.c: test image generator
- Makefile (OBJS): added tstimg.o
- Makefile (LDFLAGS): tstimg.c needs libm
- ubb-vga2.c (session, main): pass image generator as a function pointer
- ubb-vga2.c (main): new option -t to select the test image generator
- ubb-vga2.c (session, grab): made the frame buffer "void *" and pass
frame buffer resolution
- ubb-vga.h: color encoding and items shared between compilation units
- ubb-vga2.c (thres, pattern, grab), grabfb.c: move to grabfb.c
- ubb-vga2.c (map): make global, for use by grabfb.c
- ubb-vga2.c (pick, pattern, tricolor, grid): removed obsolete test
image generators
- Makefile (OBJS, ubb-vga2): added grabfb.o
- Makefile (clean): remove only .o files
- Makefile (spotless): remove only executables
- ubb-vga2.c (frame, grab, session): keep all 480 lines in the frame
buffer instead of duplicating them on output
- ubb-vga2.c (bad): make "static"
- ubb-vga2.c (session, main): removed the "single" argument
- ubb-vga2.c (main): complain about timeouts only if any occurred
