当然可以,以下是一个简单的 Python Joystick 开发程序:
```python
import time
import struct
import sys
import os
if os.name == 'nt':
import msvcrt
else:
import termios
import fcntl
import sys
import os
class Joystick:
def __init__(self, device_file):
self.device_file = device_file
self.axis_states = {}
self.button_states = {}
# Open the joystick device file
self.jsdev = open(self.device_file, 'rb')
# Get the number of axes and buttons
buf = bytearray(8)
fcntl.ioctl(self.jsdev, 0x80016a11, buf)
self.axis_count, self.button_count = struct.unpack('hH', buf)
# Print some information about the joystick
print("Joystick detected:")
print(" %d axes" % self.axis_count)
print(" %d buttons" % self.button_count)
def read(self):
# Read the joystick event data
evbuf = self.jsdev.read(8)
if evbuf:
time, value, type, number = struct.unpack('IhBB', evbuf)
# Handle axis events
if type & 0x02:
self.axis_states[number] = value
# Handle button events
if type & 0x01:
self.button_states[number] = value
def get_axis(self, axis):
if axis in self.axis_states:
return self.axis_states[axis]
return 0
def get_button(self, button):
if button in self.button_states:
return self.button_states[button]
return 0
def close(self):
self.jsdev.close()
# Example usage
if __name__ == "__main__":
# Find the first joystick device file
device_file = None
for i in range(0, 16):
if os.path.exists("/dev/input/js%d" % i):
device_file = "/dev/input/js%d" % i
break
if device_file is None:
print("No joystick device found!")
sys.exit(1)
# Create a joystick object
joystick = Joystick(device_file)
# Read joystick events forever
while True:
joystick.read()
print("Axis 0: %d" % joystick.get_axis(0))
print("Axis 1: %d" % joystick.get_axis(1))
print("Button 0: %d" % joystick.get_button(0))
print("Button 1: %d" % joystick.get_button(1))
time.sleep(0.1)
# Close the joystick object
joystick.close()
```
这个程序使用了 Linux 下的 /dev/input/jsX 设备文件来读取 Joystick 的输入。如果你使用的是 Windows,你需要使用另外的方法来读取 Joystick 的输入。
