Hardware requirements

  • Micro USB cable

  • RD-RW61X-BGA board

  • Personal Computer

Board settings

No special settings are required.

Prepare the Demo

  1. Connect a micro USB cable between the PC host and the MCU-Link USB port (J7) on the board

  2. Open a serial terminal with the following settings:

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One stop bit

    • No flow control

  3. Download the program to the target board.

  4. Launch the debugger in your IDE to begin running the demo.

Running the demo

The log below shows example output of the frequency measure demo in the terminal window:

Capture source: External clock (clk_in) (main system clock reference), reference frequency = 260000000 Hz
Computed frequency value = 39999160 Hz
Expected frequency value = 40000000 Hz

Capture source: SFRO clock (main system clock reference), reference frequency = 260000000 Hz
Computed frequency value = 15999069 Hz
Expected frequency value = 16000000 Hz

Capture source: FFRO clock (main system clock reference), reference frequency = 260000000 Hz
Computed frequency value = 48301200 Hz
Expected frequency value = 48301886 Hz
