To run the Quick Start Example Project, use the following instructions:
1. On power up or RESET, the user LED (LED1) starts blinking red at 1 Hz.
2. Press the user button (S1, USER BTN) on the EK-RA2A1 board to change the blinking frequency of
LED1. With every button press, the frequency will switch from 1 Hz to 5 Hz to 10 Hz and cycle back.
3. On the host PC, open Windows Device Manager. Expand Ports (COM & LPT), locate USB Serial
Device (COMxx) and note down the COM port number for reference in the next step.
Note: USB Serial Device drivers are required to communicate between the EK-RA2A1 board and the
terminal application on the host PC.
