May 1, 2025May 2025: Delivered critical STM32 domain enhancements in analogdevicesinc/no-OS, focusing on PWM timing accuracy, trigger flexibility, and robust interrupt handling. Key outcomes include ETR (External Trigger) support and Gated mode for the STM32 timer PWM driver, plus a generic IRQ Set Pending API with STM32-specific Set/Clear Pending implementations wired into the IRQ operations table. These changes broaden hardware integration, improve testability, and enable more deterministic, timing-critical applications in customer deployments.

Mar 1, 2025March 2025 monthly summary for analogdevicesinc/no-OS focusing on DMA subsystem reliability. Delivered a critical bug fix: ensure memory is deallocated across all channels in the DMA remove API by iterating each channel's sg_list. This change eliminates memory leaks and ensures proper resource cleanup, improving runtime stability in multi-channel DMA scenarios. The work reduces risk of memory-related issues in production and strengthens overall software reliability.
