Hello friends,I want to send rc values to Pixhawk from Raspberry Pi,I found this code but ı want to serial communication instead of Udp how can ı change this code thanks a lot
# Import mavutil
from pymavlink import mavutil
# Create the connection
master = mavutil.mavlink_connection('udpin:0.0.0.0:14550')
# Wait a heartbeat before sending commands
master.wait_heartbeat()
# Create a function to send RC values
# More information about Joystick channels
# here: https://www.ardusub.com/operators-manual/rc-input-and-output.html#rc-inputs
def set_rc_channel_pwm(id, pwm=1500):
""" Set RC channel pwm value
Args:
id (TYPE): Channel ID
pwm (int, optional): Channel pwm value 1100-1900
"""
if id < 1:
print("Channel does not exist.")
return
# We only have 8 channels
# https://mavlink.io/en/messages/common.html#RC_CHANNELS_OVERRIDE
if id < 9:
rc_channel_values = [65535 for _ in range(8)]
rc_channel_values[id - 1] = pwm
master.mav.rc_channels_override_send(
master.target_system, # target_system
master.target_component, # target_component
*rc_channel_values) # RC channel list, in microseconds.
# Set some roll
set_rc_channel_pwm(2, 1600)
# Set some yaw
set_rc_channel_pwm(4, 1600)
# The camera pwm value is the servo speed
# and not the servo position
# Set camera tilt to 45º with full speed
set_rc_channel_pwm(8, 1900)
