How to Use

Begin by installing the appropriate development environment toolchain on your computer. Download the ARM GCC compiler or use Keil MDK if you prefer a commercial IDE with integrated debugging. Connect the CoAction Hero to your computer using a USB cable or dedicated JTAG programmer, then install the necessary drivers for your operating system. The board will appear as a serial device, allowing you to upload firmware and monitor debug output through terminal applications.

Configure your development project by linking the appropriate startup code and peripheral libraries provided in the open-source repository. Define your GPIO pins, configure clock settings, and initialize communication protocols such as UART or SPI according to your application requirements. Leverage the extensive example code and datasheets available in the community documentation to accelerate development. Use the SWD or JTAG interface to flash your compiled firmware directly onto the board, set breakpoints for debugging, and monitor real-time variable values during execution. Test your application with connected sensors and modules, utilizing the multiple I/O ports and analog channels to validate functionality before deploying to production environments.
