Remote Decoder Sample
This sample demonstrates reading remote controller PWM channels from an RC receiver.
- 1.Download the sample code from https://github.com/Turta-io/RCDriverHAT/blob/master/Samples/Python/Remote_Decoder.py
- 2.Copy the sample code to a folder on the Raspberry Pi.
- 3.Open terminal, and then go to the folder you copied the sample.
- 4.Run the sample with the following command:
python3 Remote_Decoder.py
Remote_Decoder.py
#!/usr/bin/env python3
#This sample demonstrates reading remote controller PWM channels from an RC receiver.
#Install RC Driver HAT library with "pip3 install turta-rcdriverhat"
from time import sleep
from turta_rcdriverhat import Turta_RCDriver
#Initialize
rc = Turta_RCDriver.RCDriver()
try:
#Activate fan at 50% speed
rc.set_fan(50)
while True:
#Option one: Read all PWM channels in one shot
#Useful when you need all the reading wihtin a minimal time
pwm_all = rc.read_pwms()
#Print the readings
if pwm_all is not None: #Check if data is received
print("PWM St....: " + str(pwm_all[0]))
print("PWM Th....: " + str(pwm_all[1]))
print("PWM A3....: " + str(pwm_all[2]))
print("PWM A4....: " + str(pwm_all[3]))
#Wait
sleep(1.0)
#Option two: Read PWM inputs one by one
#Useful when you need only one reading
pwm_s = rc.read_pwm(Turta_RCDriver.PWM_IN.STEERING)
#Print the reading
if pwm_s is not None: #Check if data is received
print("PWM St....: " + str(pwm_s))
#Wait
print("-----")
sleep(1.0)
#Exit on CTRL+C
except KeyboardInterrupt:
print('Bye.')
When you run the sample, it prints PWM pulse lengths applied to the receiver port. The example output should be like this:
PWM St....: 1204
PWM Th....: 1412
PWM A3....: 0
PWM A4....: 0
PWM St....: 1204
-----
To stop the Python script, just press CTRL + C.
