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 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 7a42b2e088 Add 0x04_pwm_cbm: bare-metal RP2350 PWM driver 
- PWM slice 4, channel B on GPIO25 (onboard LED)
- Duty cycle sweep 0-100% in 5% steps for breathing effect
- Wrap 9999 with no clock division (~650 Hz from ROSC)
- UART reports each duty step
- 1390B FLASH, 11 source files, zero warnings
