RF433pico is a Micropython library to connect RF433mhz receivers such as MX-05V, and remote control transmitters.
The code was based on https://github.com/AdrianCX/pico433mhz library and contains some modifications.
MX-05V voltage operation is 5v and Raspberry Pi Pico 3v3, to avoid burning your gpio use a logic level converter.
You could try to connect the MX-05V in 3.3v but the receiver will work only at a short distance, such as 10cm. If it's enough for your case, go ahead!
This library was tested only in a Raspberry Pi Pico with Micropython 1.19.1v, It means lower versions or another devices could have some problem.
Simple example:
import time
from rf433pico import RFReceiver
# Creating a new RFReceiver instance
receiver = RFReceiver(pin_number=18, debug=True)
# Enabling receiver
receiver.enable()
while True:
if receiver.code and receiver.code_timestamp:
print(
'{ "code": "'
+ str(receiver.code)
+ '", "pulse_length": "'
+ str(receiver.pulse_length)
+ '", "protocol": "'
+ str(receiver.proto)
+ '" }'
)
receiver.clear()
time.sleep(0.05)Listener example:
from rf433pico import RFReceiver, RFIncomingMessage
# Creating a new RFReceiver instance
receiver = RFReceiver(pin_number=18, debug=True)
# Enabling receiver
receiver.enable()
def callback(incoming_message: RFIncomingMessage):
print(f"LISTENER CALLBACK:{incoming_message}")
receiver.add_listener(callback)
# To remove a listener:
# receiver.remove_listener(callback)
# or to remove all listeners
# receiver.clear_listeners()By default, debug parameter is False, debug active a internal function using print nothing else.
When you use listeners, behind the scenes the library uses a micropython.schedule inside of a IRQ callback. That was my attempt to follow the Mycropython recommendations of IRQ.
