Tip: The source code can be downloaded from: VisionFive.gpio. sudo yum install python-devel python3-devel sudo python setup.py install Alternatively, you can execute the following command: sudo python3 setup.py install © 2018-2022 StarFive Technology www.starfivetech.com All rights reserved... -
Page 10: Running Demo Code
If the value is out of the range (200 to 20000 Hz) , a warning message will display, and you need to re- enter the pitch value. ◦ Enter Cycle (seconds): The time in seconds when the buzzer keeps beeping. For example, Example: [riscv@fedora-starfive sample-code]$ sudo python3 buzzer.py Enter Pitch (200 to 20000): 400 Enter Cycle (seconds): 100 Result: The buzzer keeps beeping for 100 seconds at 400 Hz. -
