Safe interrupt service routines require minimal logic, deferred processing, and synchronization. This Skill helps design short ISRs, configure DMA transfers, and apply timeout-based error handling to maintain reliable timing on STM32 and ESP32 microcontrollers.

Low-power microcontroller firmware requires careful power optimization, scheduled sensor reads, and efficient resource usage. This Skill implements low-power design strategies for RTOS-based devices, ensuring battery life is maximized without missing real-time deadlines.

Configuring bare-metal communication buses involves hardware initialization, peripheral setup, and robust error handling. This Skill develops reliable drivers for SPI, I2C, CAN, and UART, applying timeout-based error handling and synchronization for noisy real-time conditions.

Debugging timing jitter and optimizing RAM requires stack checks, watchdogs, and timing analysis. This Skill optimizes flash, RAM, latency, and jitter in FreeRTOS applications while validating behavior through resource usage accounting and timing analysis.

Yes, this approach supports DMA transfers and bare-metal drivers without an RTOS. It applies to STM32 and ESP32 platforms, handling hardware initialization and peripheral configuration for GPIO, timers, and ADC with robust error handling even in bare-metal environments.
