A module to control VisionFive GPIO ports
Project description
This package provides a Python module to control the GPIO on a VisionFive SBC.
Support basic GPIO function including I/O, edge detection, PWM, I2C, SPI. Although hardware PWM is not available yet, software PWM is available to use on all channels.
Installation
Pypi does not support uploading binaries of RISC-V architectures, there are two ways to install VisionFive.gpio:
pip:
First, access the following website to check the latest version number of VisionFive.gpio: https://pypi.org/project/VisionFive.gpio/#history
Replace “1.x.x” in the following URL with the latest version number obtained from the above step: https://pypi.org/project/VisionFive.gpio/1.x.x/#files
Visit the modified URL, for example: https://pypi.org/project/VisionFive.gpio/1.2.12/#files
Hover over the file with the “.whl” extension (e.g., VisionFive.gpio-1.2.12-cp34-abi3-any.whl) and right-click to copy the link address.
Download the .whl installation package using the wget command:
>>> wget download_address_of_whl_package
Rename the .whl package by replacing “any” with “linux_riscv64”:
>>> mv VisionFive.gpio-1.2.12-cp34-abi3-any.whl VisionFive.gpio-1.2.12-cp34-abi3-linux_riscv64.whl
Finally, install the .whl package using the following command:
>>> pip install VisionFive.gpio-1.2.12-cp34-abi3-any.whl
script:
You can use the method provided in the following URL to install the script: https://doc-en.rvspace.org/VisionFive2/AN_Edge_Detection/VisionFive2_ApplicationNotes/Shared_preparing_software%20-%20vf2.html
Usage
Same as RPi.GPIO, help and usage of APIs can be obtained through help() API:
>>> import VisionFive.gpio as GPIO
>>> help(GPIO)
>>> help(GPIO.setup)
Sample Code
Support python sample, such as:
GPIO basic operation including input and output
Sense HAT(B) basing I2C API
LED_Matrix to display logo about Starfive
uart_gps_demo to read gps information from GPS NEO-6M
pwm_led to test PWM module works well
edge_detection_basic about basic edge API usage
edge_with_waiting_time about edge detection with specific time
edge_with_LED_Matrix about trigger LED display by button
RPi_demo_#GPIO_basic#_run_on_VisionFive about running RPi GPIO demo on VisionFive board
RPi_demo_#PWM#_run_on_VisionFive about running RPi PWM demo on VisionFive board
All demos above are on the example folder.
