41 Version 0.3 of the draft spec. This includes a description of the ZipOS,
the various files, how the pinouts support the PMods, and so forth. A *big*
rewrite.
dgisselq 2266d 22h /
40 Added in internal document links, so you can click on contents items
(for example), and go directly to the referenced section.
dgisselq 2269d 23h /
39 Fixes the doorbell light, so that it goes on and off properly now. dgisselq 2272d 16h /
38 Updated the documentation. dgisselq 2272d 16h /
37 Fixed the problem with the clock running too slow. dgisselq 2273d 14h /
36 Many updates to the SPEC, although it's still by no means complete. dgisselq 2275d 14h /
35 Minor updates and tweaks, primarily fixing the none_sel signal when the
RTC, scope, or ICAPE interface are not present.
dgisselq 2275d 14h /
34 Adjusted this so that the "*.c" files are now archived. Also, I didn't
need archiving of python files, so that extension was removed as well.
dgisselq 2275d 14h /
33 Adjusted the defaults, so that more values have defined default values. dgisselq 2275d 14h /
32 Removed an undefined value from o_lcd[2] setting. dgisselq 2275d 14h /
31 Fixed a bug caught by Verilator. dgisselq 2275d 14h /
30 Brings the CPU up to date with the rest of the ZipCPU distribution. dgisselq 2275d 14h /
29 A first capability for setting time, dawn, and dusk values using the keypad.
At this point, I now have a minimal capability for actually accomplishing
the entire task. It's not very robust, but if you get lucky it'll work.
dgisselq 2275d 14h /
28 Fixed a small lint bug associated with the scope vs the compressed scope. dgisselq 2280d 01h /
27 Added a bootloader capability so that pieces of the program may be immediately
loaded into RAM. Further, the custom linker script, cmodram.ld, has been
added to dispatch object files to either FLASH or RAM. Finally, for those
items that were headed to RAM, their support files have been split between
RAM and FLASH code: kernel.c/ksetup.c, syspipe.c/pipesetup.c, etc.
dgisselq 2280d 01h /
26 Modified to be able to handle different load from virtual addresses. This
enables the bootloader capability.
dgisselq 2280d 01h /
25 Converted timer B to be a non-reloadable watchdog timer. dgisselq 2280d 02h /
24 Made the ziptimer autoreload feature a parameter (dis)abled option. dgisselq 2280d 02h /
23 Fixed a bug which caused every instruction to be loaded/prefetched twice. dgisselq 2280d 02h /
22 Initial version of the ZipOS operating system construct(s). dgisselq 2284d 00h /
