Remove initialization from data structure.
Replace the previous virtual_init() with a virtual_init() that initializes the
data structures to a default state
Create virtual_sync() function to push the state of virtual devices to the
physical outputs. Moved from the previous virtual_init() function.
The virtual device table is now built by direct calls to virtual_add() from the
setup function.
Toward issue [#23]
Clean compile of asdf_keymaps.c/h and tests
Clean up keymap pointer notation
Reduce number of keymaps to 16, matching number of DIP switches allocated for
keymap selection.
(WARNING: WIP) Gathered Work-in-progress on alternate keymap defs
Exploratory branch. Code is messy and untested.
Examining creating a module for each keymap rather than header file.
- CMake build process handles dependencies much more effectively
- Cleaner separation of test and binary builds
- permit co-existing test and multiple architecture builds
- add support for AVR from cmake-avr:
https://github.com/mkleemann/cmake-avr
- new build process avoids creating files in the src directory
- Rename asdf_hook_do() to asdf_hook_execute()
- asdf.c: Call asdf_hook_execute() for ASDF_HOOK_EACH_SCAN hook call in the scan
routine, instead of getting then calling the function via hook_get()
- asdf.c: move the fetch of scan function hook outside the scan loop.
- arch-* files: replace private arch_strobe_init() function with public
arch_set_neg_strobe() and arch_set_pos_strobe() functions
- asdf.c,h: add ACTION hooks to set strobe polarity and enable/disable
autorepeat
- break out DIP switch definitions into a separate header file, included by each
keymap. This ensures consistent DIP switch behavior across keymaps.
- Add Keymaps/asdf_keymap_defs_sol.h, and add the hooks in the master keymap
- asdf.h: Change start of ACTION codes to 0xA0, since SOL-20 uses codes from 0x80-0x9a
- asdf_ascii.h: Add named ASCII control codes to
- Replace V_PULSE with V_PULSE_LONG and V_PULSE_SHORT functions.
- replace the asdf_arch_pulse_delay() with asdf_arch_pulse_delay_short() and
asdf_arch_pulse_delay_long() functions.
- modify keymaps to use long and short pulses.
- long pulse is 50 ms. Short pulse is 10 us.
- Added localizing prefix to keymap definitions to avoid conflicts.
The apple 1 CLEAR input requires a high-impedance inactive state to avoid
conflict with the pin output of the 7404 at D12 (via CR4). So, to cover this
condition most generally, this patch changes the adds a Hi-Z when low physical
device for each output line, to complement the Hi-Z-when-high open collector
emulation. The nomenclature is changed from OUT*_OC (emulated open collector) to
OUT*_OPEN_HI and OUT*_OPEN_LO to indicate which condition gets the Hi-Z state.
- added the set() functions to the asdf_arch_atmega328p.[ch] files and applied
the above nomenclature.
- Added the set() functions to the asdf_physical.[ch] files and applied the
above nomenclature
- Modified the SCREEN_CLEAR device to PHYSICAL_OUT1_OPEN_LO in the apple2 and
ascii keymaps.
- Changed the RESET from PHYSICAL_OUT1_OC to PHYSICAL_OUT1_OPEN_HI in the apple2
and ascii keymaps.
