即使我试图从grovepi获取其他数据，也是同样的问题…：

import grovepi

dht_sensor = 5

moisture = 1

moist = grovepi.analogRead(moisture)

#[temp,hum] = grovepi.dht(dht_sensor, 0)

print(moist)

错误：

pi@raspberrypi:~/Desktop $ python3 t.py ^CTraceback (most recent call last): File "/usr/local/lib/python3.7/dist-packages/grovepi-1.4.1-py3.7.egg/grovepi.py", line 228, in read_i2c_block KeyboardInterrupt
During handling of the above exception, another exception occurred:
Traceback (most recent call last): File "t.py", line 7, in moist = grovepi.analogRead(moisture) File "/usr/local/lib/python3.7/dist-packages/grovepi-1.4.1-py3.7.egg/grovepi.py", line 261, in analogRead File "/usr/local/lib/python3.7/dist-packages/grovepi-1.4.1-py3.7.egg/grovepi.py", line 242, in read_identified_i2c_block File "/usr/local/lib/python3.7/dist-packages/grovepi-1.4.1-py3.7.egg/grovepi.py", line 232, in read_i2c_block KeyboardInterrupt pi@raspberrypi:~/Desktop $ ^C

更改的PI总线：

grovepi.set_总线（“RPI_1”）

现在能用了，伊芙，如果它以前能用，不用换车

我想是线的干扰。多个线程试图读取/写入同一传感器上的数据

我做到了这一点，因此它不会为读取和显示数据的特定情况打开多个线程

可以关闭
