IR NEC Sample
This sample demonstrates sending infrared remote controller messages using NEC protocol.
- 1.Download the sample code from https://github.com/Turta-io/IoTHAT3/blob/master/Samples/Python/IRRemote_NEC.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 IRRemote_NEC.py
IRRemote_NEC.py
#!/usr/bin/env python3
#This sample demonstrates sending infrared remote controller messages using NEC protocol.
#Install IoT HAT 3 library with "pip3 install turta-iothat3"
from time import sleep
from turta_iothat3 import Turta_IRRemote
#Initialize
ir = Turta_IRRemote.IRRemoteTx()
try:
while True:
#Prepare the payload
payload = [0x01, 0xFE, 0x02, 0xFD]
#Send remote controller message in NEC protocol
ir.write(Turta_IRRemote.PROTOCOLS.NEC, payload)
#Print the payload
print("IR Message Sent..: " + str(payload))
#Wait
sleep(2.0)
#Exit on CTRL+C
except KeyboardInterrupt:
print('Bye.')
When you run the sample, it sends payload data using the onboard IR transmitter. The example output should be like this:
IR Message Sent..: [1, 254, 2, 253]
To stop the Python script, just press CTRL + C.
