Develop ESP32 firmware with Zigbee

firmware-engineersubagentsetup L3★1

What it does

Develop firmware for embedded systems and hardware integration

Best for

Implementing resource-constrained embedded code with deterministic timing, memory safety, and robust error recovery for hardware control and sensor integration.

Inputs

· hardware schematic
· MCU firmware specification
· protocol requirements

Outputs

· C/Rust firmware
· bootloader
· hardware test harness

Requires

· RTOS (FreeRTOS/Zephyr)
· embedded toolchain
· JTAG debugger

Preconditions

· MCU chosen
· pinout documented
· clock/power budget verified

Failure modes

· stack overflow if allocation unbounded
· memory corruption if bounds check missing
· brownout if power draw not validated

Trust signals

· memory safety validation (bounds checks)
· power budget audit
· timing analysis (real-time guarantees)
· hardware test harness
· bootloader resilience
