- adc: Use derive(Default) for VTemp/VRef, remove useless conversion - dma: Replace manual non-exhaustive pattern with #[non_exhaustive] - exti: Use range patterns (0..=3) instead of OR patterns - gpio: Remove unused borrows and add cfg guards for unused imports - i2c: Use manual_range_contains pattern - qei: Remove legacy numeric constant import - rcc: Use derive(Default) for MSIRange enum - serial: Use #[non_exhaustive] and iter() instead of into_iter() - spi: Use #[non_exhaustive] attribute - time: Use From instead of Into, remove unnecessary drop()
- Add RTC backup register methods (read/write_backup_register) - Add RTC initialization check methods (is_initialized/mark_initialized) - Fix critical bug: use modify() instead of write() for RCC registers - Prevents unintended disabling of other clock sources - Affects: CR, ICSCR, CFGR, APB1ENR registers - Fix register access in multiple peripheral drivers: - rtc.rs: APB1ENR register - rcc.rs: CR, ICSCR, CFGR registers - adc.rs: CR register - timer.rs: DIER, SR registers - serial.rs: CR1, CR2 registers - pwm.rs: CR1 register - spi.rs: CR1, CR2 registers - watchdog.rs: CR, CFR registers Using write() overwrites entire registers, potentially disabling other peripherals. Now using modify() to preserve existing configuration.
- Add rtc_backup_simple.rs: demonstrates backup register usage - Power-loss detection with magic number - Boot counter that persists across resets - Multiple backup register usage - Add rtc_backup.rs: complete RTC example with timekeeping - RTC initialization check - Date/time setting and reading - RTC wakeup timer - Backup register boot counter - Add examples/README.md - Comprehensive documentation for all examples - RTC backup register feature documentation - Building and running instructions - Hardware requirements and troubleshooting
- Remove unused gpioe and gpioh imports in gpio macro - Change MCO configuration to use .bits() instead of .variant() for stm32l100 compatibility - All variants (stm32l100, stm32l151, stm32l152, stm32l162) now compile without warnings
- rtc_backup.rs: prefix unused rcc variable with underscore and remove mut - button_irq.rs: replace deprecated NVIC.enable() with NVIC::unmask()
- Break long method chains into multiple lines for better readability
- button_irq.rs: remove unused prelude import and cp variable - timer.rs: replace NVIC.enable() with NVIC::unmask() - rtic.rs: replace clear_irq() with clear_interrupt_pending_bit()
