For better matching of current limit resistors to LEDs, the resistors are moved
to the keyboard matrix PCB, where they can be tuned for maximum brightness (at
100% duty cycle). This allows consistent keyboard brightness when a single
interface PCB is swapped between keyboard matrices.
- 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.
- Fixed position offset error in first three rows of the SOL keyboard
- moved key matrix interface connector to bottom of board so the parallel output
connector can be at the top of the keyboard.
- Adjusted size of mounting slots to accommodate #6 screws.
- ongoing clean up of traces.
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.
- asdf_modifiers.[ch]: Replace asdf_modifier_shiftlock_activate() with
asdf_modifier_shiftlock_on_activate() and
asdf_modifier_shiftlock_toggle_activate(). Instead of a configurateion
setting for shiftlock state to switch between SHIFTLOCK locks on, SHIFT turns
off, vs SHIFTLOCK toggles, and SHIFT turns off, create two different
SHIFTLOCK functions, one for each behavior, and allow the keymap to bind the
desired function.
- asdf.h: replace ACTION_SHIFTLOCK with ACTION_SHIFTLOCK_ON and
ACTION_SHIFTLOCK_TOGGLE.
- asdf.h: move start of ACTION codes from 0x80 to 0x90, since SOL-20 uses codes
from 0x80-0x8f.
- asdf.c: test for ACTION code using (code > ASDF_ACTION) instead of (code &
ASDF_ACTION), since ASDF_ACTION need not be a power of 2.
- asdf_modifiers.[ch] and other files: remove
asdf_modifiers_shiftlock_deactivate() and
asdf_modifiers_capslock_deactivate(), and any references to these functions
since they are null functions anyway.
- Split asdf_virtual.c into asdf_physical.c and asdf_virtual.c, moving the
functions that handle the physical resources to asdf_physical.c
- cleaned up nomenclature to be more consistent and less confusing.
- fixed keymap files and tests to use asdf_physical.c/h and new nomenclature.
- added asdf_physical.c to Makefiles.
Disallow assignment of invalid virtual or real devices
Disallow assignment of a real devices that have already been assigned.
add unit test cases for virtual devices
* Created test fixture for virtual outputs
* Added virtual output configuration to keymap definitions removed special
actions_send_reset() and actions_send_screenclear() functions, and replaced with
virtual output definitions.
* asdf_actions.c is removed from build.
* asdf_arch_atmega328p.c: added functions to set/clear each real output
* asdf_arch_atmega328p.c: added pulse_delay() function
* asdf_arch_test.c: added mock machinery to emulate outputs, test output
settings, and detect properly and improperly-formed pulses on the outputs.
* asdf_keymaps.c: allocate initialzer array. asdf_keymaps_select_keymap() calls
asdf_virtual_init() with initializer list for the keymap to set up the LEDS and
outputs every time a new keymap is selected.
This allows the keymap to determine which LED is used, rather than requiring the
decision to be hardwired in at the time of assembly. For the OSI keyboard, the
LED could be placed on the SHIFTLOCK key, at the far right LED, or in the
CAPSLOCK position, which is just to the left of the RETURN and not otherwise
populated in the OSI layout.
- swap numbering of row select protection diodes for cleaner PCB labeling
- clarify labeling on GPIO pins on the MCU
- bump rev to 2.4 to indicate work in progress. Release will be 2.5.
- asdf_modifier.c: refactor CAPS LOCK setting and add LED setting
- asdf_arch_atmega328p.[ch]: add in LED definitions and functions
- add dummy asdf_arch_caps_led() function to arch files so test can compile.
