ADuCM3029 Blinky no-OS Example Project

See projects/aducm_blinky_example (doxygen) for the Doxygen documentation.

The ADuCM3029 Blinky Example is a simple demonstration project for the EVAL-ADICUP3029 platform, which is based on the ultra low power ADuCM3029 ARM Cortex-M3 microcontroller. The project uses the no-OS GPIO driver to toggle the on-board LEDs (DS3 green, DS4 blue) in a binary count pattern, demonstrating basic GPIO control without an operating system.

The ADuCM3029 features single-supply operation from 1.74 V to 3.6 V, with active mode dynamic current of 30 uA/MHz and hibernate mode current of 750 nA.

No-OS Supported Examples

This project is organized around the no-OS variant based build flow. Selecting a variant at build time (--variant <name>) chooses which application is compiled. The platform main() is a thin dispatcher that calls example_main(), provided by the selected example. The initialization data used in the examples is defined in src/common, and the platform-specific macros in src/platform.

Basic Example

This is the default example (basic variant) which initializes the GPIO pins for the on-board LEDs (DS3 green, DS4 blue) and toggles them in a blink pattern.

No-OS Supported Platforms

ADuCM3029

Used Hardware

EVAL-ADICUP3029

Connections

Connect the EVAL-ADICUP3029 to a PC via micro USB cable. Ensure the UART switch is set to the USB position for serial terminal communication.

Build Command

For toolchain setup and prerequisites, see the ADuCM3029 CMake build guide.

Available variants: basic. Available boards: eval-adicup3029. Replace --variant / --board accordingly.

# point at the CrossCore Embedded Studio install (only if not auto-detected)
