- New units: usbtypes, usbcore, usbhub, UHCI, OHCI, usb_keyboard,
usb_mouse
- usbtypes: shared USB descriptors, constants, HC abstraction,
aligned alloc, unit tests
- usb_keyboard: USB HID boot keyboard driver with HID-to-ASCII
translation, polling, unit tests
- usb_mouse: USB HID boot mouse driver with delta/scroll/button
processing, polling, unit tests
HID Layer Restructure:
- keyboard.pas: stripped to abstract API (hook + reportKeyEvent),
no PS/2 dependency
- mouse.pas: absorbed mousestate.pas, now owns
position/buttons/scroll/hooks directly
- mousestate.pas: deleted (merged into mouse.pas)
- New ps2_keyboard.pas: PS/2 scan code translation,
calls keyboard.reportKeyEvent
- New ps2_mouse.pas: PS/2 packet handling, calls
mouse.setMousePos/fireMouseEvent
LVGL Integration:
- lvgl.pas: updated to use mouse.pas directly (was mousestate),
improved keyboard input handling with proper key held/release tracking
- vterminal.pas: removed serial debug logging, dropped serial dependency
Kernel:
- kernel.pas: added USB units, USB polling in main loop, unit test
calls, ps2_keyboard/ps2_mouse init
refactor(stdio): replace console/terminal command system with buffer-based stdio
- Introduced stdio.pas as the unified command I/O layer.
- All 31 command procedures across 15 files now receive stdin_buf,
stdout_buf, and stderr_buf (POutBuf) instead of a single outbuf.
- vterminal.pas creates all three buffers per command invocation and
displays both stdout and stderr.
- Deleted console.pas, terminal.pas, and 9 obsolete windowing programs
(shell, splash, edit, memview, themer, netlog, vmlog, vmstate, udpcat).
- Migrated all registerCommand calls to stdio, rewrote vterminal
processCommand to use stdio.findCommand, and added proper error
routing to stderr for invalid params, bad paths, and system errors.
refactor(syslog): replace console logging with serial-backed syslog
- Introduced syslog.pas for kernel-level logging over serial/dev.
- Migrated all boot logging in kernel.pas from console.outputln/
writestringln to syslog.logln/writestringln.
- Converted 19 fault handlers, hashmap, lists, scheduler, tracer, net,
udp, and all driver init paths to use syslog.
- Rewrote BSOD in util.pas (50+ calls) from console to syslog.
- Removed CONSOLE_SLOW_REDRAW, TRGB565, TRGB565Pair, and HWND
from system.pas.
fix(keyboard): add ring buffer and proper press/release cycling for LVGL input
- Replaced the single last_key/key_pressed slot in lvgl.pas with a
16-entry ring buffer (kb_buf, kb_head, kb_tail) to prevent ISR
overwrites when typing fast.
- Added a kb_pending_release flag so each keystroke gets a
full PRESSED->RELEASED cycle before the next key is consumed —
LVGL requires this pairing and was silently dropping intermediate
keys when receiving consecutive PRESSED events without
intervening releases.
feat(vterminal): use Hack monospace font for terminal output
- Added Hack Regular 14px (hack_14.c) as a custom LVGL font.
- Removed the .static_bitmap field from the generated font file
(not present in LVGL 9.2 lv_font_t struct).
- Declared the hack_14 external symbol in lvgl.pas and switched
vterminal's text label from lv_font_montserrat_14 to hack_14
for proper monospace terminal rendering.
Added the apache license to all source files, accounting for authors. Also added a license.md containing the apache license + contributors.md listing all contributors.
