Kevin Thomas e2d2b21551 fix(ir_cbm): clear PDE bit in pad config for proper pull-up input
PADS_BANK0 GPIO5 had PDE (pull-down enable, bit 2) still set to its
reset default. With both PUE and PDE active the pin floated to ~VDD/2,
causing the Schmitt trigger to read LOW permanently. Clear PDE in
_configure_pad() so the pull-up works correctly.

Added PADS_BANK0_PDE_SHIFT define to rp2350.h.

Kevin Thomas 8f20fcde28 fix(dht11_cbm): add dummy read on init to prevent first-read failure 2026-04-06 17:26:05 -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 e6d8ab4850 refactor: enforce 8-line Reset_Handler limit across CBM drivers
Extract _late_init() wrappers in 0x04, 0x05, 0x0b, 0x0d, 0x0e, 0x0f
to keep Reset_Handler within the max 8 code-line standard.
