- README: added compatibility of double mode
- ubb-vga.c (usage, main): new option -d to double the number of set/clear
pairs (making lines longer and the apparent pixel clock slower)
- ubb-vga.c (grab, session, main): have a complete set/clear pair for each
pixel in double mode
- ubb-vga.c (line_pairs, line, frame, tricolor, grid, session): line
length is now kept in a variable, instead of hard-coding its value
and the values derived from it
- ubb-vga.c (line_cycles, line, hdelay): the total line duration is now
kept in a variable, instead of hard-coding it all over the place
- ubb-vga.c: added more section titles
- ubb-vga.c (pick, pattern): grouped pixel-generating functions with
image generation
- ubb-vga.c (usage, main): properly parse command-line options ("getopt"
is a bit of overkill at the moment but will be needed later)
The history of the split prefetch code:
Once up on a time, I thought that it was important to stay very close
to the "official" pixel clock. We could do this when copying 32 bit
words from cache to the GPIO set/clear registers, but not when
shifting 8 bit values as we do now.
One problem with 32 bit values is that transferring that amount of
data exceeds the time available in the hsync pulse. Hence the idea
to split the prefetch between hsync pulse and horizontal front porch.
Note that we also split prefetches between the two VGA lines of each
QVGA line. This commit does not change that mechanism.
- ubb-vga.c (line, frame): removed code fragments for prefetch split
between hsync pulse and front porch
- ubb-vga.c (line, frame): remove code fragments for measuring time
relative to the rising edge of hsync (and letting the prefetch time
control the hsync length), not the falling edge
- nanonote-nxuart.patch (avrdude.conf): typo, CMD is signal 6, not 5 (by
David Reyes Samblas Martinez)
- series, nanonote-icsp.patch (avrdude.conf): NanoNote ICSP 8:10 cable,
by David Reyes Samblas Martinez
- series, low-addr.patch: record the lowest address touched (only for
ihex, all others default to 0)
- series, skip-low-addr.patch: skip untouched addresses in avr_read
and avr_write
- nanonote.c (nanonote_open): increased register window to include clock
and MMC controller registers
- nanonote.c (gpio_function): set a pin to function or GPIO
- nanonote.c (nanonote_initpgm, nanonote_parseextparams): accept the
extended option clk=N where N is the clock frequency in (whole) MHz
- nanonote.c (nanonote_enable): if the clock option is set, switch CLK
to function and output the specified clock
- patches/series, patches/nanonote-uart.patch: renamed to
patches/nanonote-nxuart.patch
- patches/nanonote-nxuart.patch: changed ID from "nanonote_uart" to
"nanonote_nxuart"
- patches/nanonote-nxuart.patch: added "External" to title/description
- README: removed unnecessary "make" run after second "configure"
- README: added brief explanation why we need to run "configure" twice
- README: added build instructions for OpenWRT
- nanonote.c: remove some commented-out items
- nanonote.c (nanonote_powerdown): make all data lines inputs on exit,
making it more likely that the target powers down
- ubb.brd: added project name, license, and "qi-hw.com"
- ubb.brd: duplicated text on front copper layer to silk screen
- ubb.brd: changed component references to more meaningful information,
in case they are printed on a PCB
- ubb.brd: removed unused layers
- ubb.brd: bumped version number to 110207
- Makefile: added commented-out "gerber" target, as a reminder
nanonote-uart.patch:
- avrdude.conf.in: CLK is reserved for clock output
nanonote.patch:
- nanonote.c (pin_map, nanonote_setpin, nanonote_getpin): make pin map
zero-based
- nanonote.c (nanonote_setpin): instead of having out own delay loop
setting the pin repeatedly, just add the delay we need to
pgm->ispdelay+100
- nanonote.c (nanonote_setpin): increase delay for atusb-pgm
- nanonote.c (nanonote_getpin, nanonote_open): begin with all pins set
to output and switch MISO only when read
- uart.sch (D1): added value LTST-C190KRKT
- uart.sch (K1): footprint was incorrectly placed in value field
- uart.sch (K1): added value 3M 961103-5604-AR
- uart/bom: added BOM infrastructure and definitions
- components/atmega48-mmu.lib: added nSS function to pin 12
- components/atmega48-mmu.lib (RESET): renamed to nRESET
- uart.sch: removed INT and used it for nSS instead
- uart.brd: redid layout for above change
- bbl.pro (LibName2) : use ../kicad-libs/modules/8_10-card instead of
../kicad-libs/modules/usd-card
- bbl.sch: use footprint "8:10-card" instead of "uSD-Card"
- bbl.cmp, bbl.brd: updated for renaming of usd-card.fpd
- bbl/bbl.c: PD* macros now contain the REG(), making their use easier
- bbl/bbl.c: added description of the XBurst set/clear concept
- bbl/bbl.c: added comments all over the place
- bbl.pro: use stdpass in kicad-libs, not the copy in ben-wpan (the latter
project will use kicad-libs too)
- bbl.cmp: added to stop pcbnew from complaining each time we read the
netlist
