Preparing for Teensy 3 (ARM) integration, abstracting code hierarchy
- Abstracted USB Module
- Abstracted compiler specific includes for Scan, Macro, Debug, and USB modules
- Updated CMake build files to support changes
- Added abstractions necessary to main.c as well as a compiler specific include file
- Required some small API changes, shouldn't affect any other Scan modules (addition of a parameter)
- Still have the latching annoyances for some of the modifiers
- Swapped Esc and Tilde for convenience
- Removed the old Esc key from the latch list (no one needs 13 latches anyways...)
- Added the control cluster mappings (Insert, Delete, Home, End, PgUp, PgDn)
- All other misc keys are currently un-assigned if a keycap legend doesn't map to anything known
(e.g. blank keys, 000 and 00 are mapped, but your OS probably doesn't know what they mean :P)
Unfortunately, the protocol annoying, with only 3 keys having Press/Release signals.
Some of the keys were only meant to be pressed once, and do not have repeat functionality.
The current implementation is a bit slow, so some keys may get lost during USB sending.
This is probably fixable, not sure if I want to spend the time on it though.
There is a keyboard input protocol, but I'm not sure of what information can be transmitted to the keyboard.
The terminal does send some information back and forth between the keyboard, but I'm unclear of the purpose, as I can never get any response out of the keyboard.
- All spare cycles are used to get a more accurate data line sample (waaaay more than actually needed, but this helps against noise)
- Switched to a pre/release (add/remove) rather than an add->clear mechanism (or a buffer+debounce/add->clear)
- Note that a pull-down resistor is NEEDED on the data line
Adding initial version of Sony OA-S3400 converter.
- Not fully reading for usage, but 90% of the way there for typing.
- Some soldering is required for 2 keys to work properly (Shift and Shift Lock)
- Even when complete, be careful when doing multiple key combos, as the key buffer is only cleared when all general keys are released (all except Shift, Shift Lock, and Code)
Adding test macros and basic "clicker" choose support
- Better macros are still needed for the clicker
- Current macros should be separated as a sub-module
- No LEDs implement yet
- Caps Lock LED seems to be burnt out...
- Typing and modifiers fully working
- Still some features left to implement
* Stop input
* Diagnostic test
* Setting interval before starting repeat rate
* More comments
* Handling LED stats
- LEDs are working
- Reset command is working
- Basic typing is working (USB side drops some characters)
- Changing repeat rate is working
- Querying modifiers and LEDs is working
- Initial layouts are complete
- Modifiers are not fully working yet
- Keyboard output fully working
- Not all of the features are implemented yet (input, speaker, or power
detection)
- There is no plan for mouse support
Adding support for the Micro Switch 8304 Hall Effect Keyboard
- Full support (NKRO, provided the USB module can handle it)
- Full LED support (available to the macro modules per input signals)
- Reset/Hold line support
- Handles repeat rate issues (keyboard does not send key updates as most
keyboards do...)
- Uses USART instead of polling
- Supports two way communication (only 3 commands to the keyboard
though)
- Kaypro sends data as ASCII, which severely limits the handling of
modifiers
- No release signal is sent, so even faking modifiers is next to
impossible outside of Shift and Ctrl
- Includes default QWERTY and Colemak layouts
- Developed a new buffer macro, which will become the basic macro module
once all the other modules have been ported (much more efficient, as
it keeps serial scanning schemes serial, and parallel scanning schemes
such as matrix, that already serialized into a sort of buffer for the
debouncing evaluation)
- This module is quite efficient, and would be able to handle very
excessive macro processing in the future.
- If more of the keypboard communication protocol is desired, I have a
rom dump of the microcontroller (M5L8049)
- Does not output to usb yet
- USART is functionally getting characters from the keyboard and sending
beep codes and ACK request code (Baud rate properly calculated)
- Uses hard-coded keys for the PC to Keyboard commands (not desireable)
- Keyboard sends ASCII data, which makes doing things like holding
multiple keys almost impossible to detect (the board isn't NKRO
anyways, though I've found 8+ key combos that work)
Making sub-modules of matrix for HeathZenith and BudKeypad
- Parent module no longer allows for a stand-alone compile
- Added HeathZenith matrix (pinout still needs to be done)
- Updated the HeathZenith keymaps
- Changed the original example matrix.h to matrix_template.h
- Not tested yet
- Added bug fixes for the scanCol and scanRow methods
- Merged in the powered versions of scanCol and scanRow
- Added the scanDual, but still needs heavy testing
- The scanDual uses twice the memory per key, so it can only scan half
as much compared to the other scan modes
Basic matrix module for the hall effect keypad now working.
- Includes new "table pinning" setup (much easier to understand)
- Matrix layouts will be split into their own dependent modules later
- Changed the HID Raw view id (too many teensy devices on this
computer...)
- Moved the macro processing outside of the usb timer signal
(this will be slower overall, but will result in more consistant
behaviour)
Formalizing code module structure and inheritance (Large Commit)
- Commenting cleaned up
- usb_keyboard_debug is not finished yet in terms of cleanup (needs DEBUB_PRINT #ifdef's)
- Added LoadFile script generation
- Formalized KeyIndex and USBKeys data containers
- Split parts of scan_loop into Macro, USB, and main.c
- Added interface to USB modules
- Added interface to Macro modules
- Added proper Debug module enable/disable
- Include option is currently "hacked" and needs to be fixed
- Builds on Linux, but Mac and Windows needs to be tested
- Loader script generation isn't complete
- Mostly implements the features found in the old Makefile
- More pretty colours
- TODO list can be found at the top of the file
- Doesn't have any compiler detection yet, that may be a good idea to add
