Changes for version 0.01 - 2026-07-15
- Auto generated distribution with Dist::Mgr
- Added the OO Perl interface; pure Perl, with the I2C transport provided by RPi::I2C
- Added examples/fade.pl and examples/servo.pl
- Added the ON THE WIRE POD section, with I2C bus transaction diagrams
- Added the I2C ADDRESSING POD section
- Limited CI to Linux runners; RPi::I2C is a Linux-only XS dependency
- Bundled the datasheet as docs/datasheet/PCA9685.pdf and added a DATASHEET POD section pointing to it; moved the datasheet reference out of SEE ALSO (no longer a web URL)
- Renamed the distribution from RPi-PCA9685 to RPi-PWM-PCA9685, and the module namespace from RPi::PCA9685 to RPi::PWM::PCA9685 (repo: rpi-pwm-pca9685), before any CPAN release
- Restyled the technical-section point forms to leading capitals to match the sibling dists' convention: DEVICE SPECIFICS bullets, the REGISTER MAP description column, the ON THE WIRE legend and diagram captions, and the I2C ADDRESSING captions. Only leading letters changed (identifiers, hex, numbers and the addr+W/addr+R byte tokens left as-is), so every ASCII diagram's column alignment is preserved
- Added the drive param to new() ('totem' default, or 'open_drain'), the output drive type, reapplied across reset()
- Added sink_mode(), which sets open-drain plus inverted logic for current-sinking LED wiring (eg. a 3.3 V chip sinking 5 V LEDs)
- Added the DRIVING LEDS POD section covering sourcing vs sinking wiring and the open-drain requirement
