Ubuntu18.04 Python调用GPIO测试
1. 安装gpio python library
git clone https://github.com/vitiral/gpio.git
cd gpio/
sudo python3 setup.py install
2. 编写以及运行下列Python参考示例代码
import time
import gpio
tst_gpio_pin = 417 #417对应T609G扩展的GPIO17
#tst_gpio_pin = 290 #290对应T609G扩展的GPIO04
#tst_gpio_pin = 258 #258对应T609G扩展的GPIO10
#tst_gpio_pin = 343 #343对应T609G扩展的GPIO02
gpio.setup(tst_gpio_pin, gpio.OUT)
gpio.set(tst_gpio_pin, 0)
print("Starting now! Press CTRL+C to exit")
try:
while True:
gpio.set(tst_gpio_pin, 1)
print("TEST High.")
time.sleep(5)
gpio.set(tst_gpio_pin, 0)
print("TEST Low")
time.sleep(5)
finally:
gpio.cleanup()
3. 通过如下查看设置HI 和 LO
sudo cat /sys/kernel/debug/gpio| grep '417'
