ir — Onboard Infrared Transceiver

The main functionality and function of the ir module

Function

ir.receive()

Returns the string information received by the infrared receiver, so the data sent by the infrared sender must end with \n. If it is a remote control command that receives the NEC encoding protocol, use another function receive_remote_code().

ir.receive_remote_code()

Get the date from infrared remote controller. The data contains two parts: address and content, so it returns a list data which length 2. The first parameter is the address code, and the latter parameter is the data code.

ir.send(str)

Send infrared string, parameters：

• str The string data to be emitted, the function send will add the \n terminator at the end of the string automatically.

ir.start_learning()

Start infrared learning and only support remote control commands that learn the standard NEC protocol.

ir.stop_learning()

Stop infrared learning.

ir.save_learned_result(index)

Save the learned infrared coding result to the corresponding area, parameters：

• index the value range is 0 ~ 15, a total of 16 storage areas.

ir.send_learned_result(index = 1)

Send infrared learning saved infrared code, the learning result of the area with index = 1 is set as default, parameters：

• index The index value range is 0 ~ 15, a total of 16 storage areas.

ir.learn(time = 3)

Infrared learning time seconds, after calling this API will save the infrared information learned in time seconds. Default saved to the area with index = 1, parameter：

• time learning time, in seconds.

Sample Code 1：

import codey
import event

@event.start
def start_cb():
    print("start event succeeded")
    while True:
        codey.display.show(codey.ir.receive_remote_code()[1])

Sample Code 2：

import codey
import event

@event.button_a_pressed
def button_a_cb():
    print("button a event succeeded")
    codey.ir.learn()
    codey.led.show(0, 100, 0)

@event.button_b_pressed
def button_a_cb():
    print("button b event succeeded")
    while True:
        codey.ir.send_learned_result()

@event.button_c_pressed
def button_c_cb():
    print("button b event succeeded")
    while True:
        codey.display.show(codey.ir.receive())
