Kevin Thomas c386217714 style: enforce coding standard — headers, @brief on #define, Doxygen on statics, remove _ prefix, max 8 lines per function 2026-04-16 22:45:11 -04:00
Kevin Thomas 0df58712e1 Fixed improper _ 2026-04-11 10:52:10 -04:00

Kevin Thomas 066c69f24b fix: remove duplicate docstrings from public functions in .c files 
Public function docstrings belong exclusively in .h headers per
coding convention. Only static helper functions and static variables
retain docstrings in .c files. Removed 413 duplicate docstrings
across 185 files (15 CBM + 15 C SDK projects). All 30 projects
rebuild with zero errors.

Kevin Thomas 3604b3c921 refactor: enforce max 8 code lines, add docstrings, fix warnings across all Rust and C SDK projects 
Rust (all 15 projects):
- Refactored overlength functions: format_counter, format_u8, format_f32_1,
  format_u32_minimal, gpio_drive, read_sensor, poll_sensor, format_round_trip,
  format_u32, prepare_write_buf, write_min_digits, write_temp, UartDriver::init,
  init_spi, angle_to_pulse_us, compute_servo_level
- Added 200+ docstrings to test functions, mock structs, impl blocks
- Fixed pub static comments (//) to doc comments (///) in all main.rs files
- Fixed helper function ordering (helpers above callers)
- Fixed Fn(u32) -> FnMut(u32) bound in button poll_button
- Moved OneShot trait import from main.rs to board.rs in adc project
- Added unsafe {} blocks in flash unsafe fn bodies (Rust 2024 edition)
- Removed unused hal::Clock imports from pwm/servo main.rs
- All 15 projects build with zero errors and zero warnings

C Pico SDK (all 15 projects):
- Added docstrings to all public functions, macros, and static variables
- All 15 projects rebuilt with zero errors

Cleanup:
- Removed build/ and target/ directories from git tracking
- Added target/ to .gitignore
- Deleted temporary fix_rust_docs.py script

Kevin Thomas c6c3d4a045 remove unused coprocessor driver from all CBM projects 
No project uses floating-point, so coprocessor_enable() was dead code.
Removes rp2350_coprocessor.c/.h and all references from reset handlers
and Makefiles across all 15 CBM drivers (0x01-0x0f).

Kevin Thomas 6bb722ddee fix: correct 14.5 MHz to 12 MHz across all CBM projects 
- Update all docstrings from 14.5 MHz to 12 MHz XOSC (29 files)
- Fix 0x05_servo_cbm divider: INT=14/FRAC=8 (14.5) -> INT=12/FRAC=0 (12)
- Verified against RP2350 datasheet, Pico 2 board schematic, and SDK

Kevin Thomas d912771a5e Add 0x03_button_cbm: bare-metal RP2350 button driver 
- GPIO15 active-low button input with internal pull-up
- 20ms software debounce via busy-wait confirmation
- LED mirrors button state, UART reports edge transitions
- New gpio_config_input_pullup() in GPIO driver
- 1555B FLASH, 13 source files, zero warnings
