# Create a button object to trigger IR transmit
button = digitalio.DigitalInOut(board.GP0)
button.direction = digitalio.Direction.INPUT
button.pull = digitalio.Pull.DOWN

pulseout = pulseio.PulseOut(board.GP1, frequency=38000, duty_cycle=2**15)
encoder = adafruit_irremote.GenericTransmit(
   header=[9500, 4500], one=[550, 550], zero=[550, 1700], trail=0
)

while True:
    if button.value:
        print("IR signal sent!")
        encoder.transmit(pulseout, [31, 31, 152, 103])
        time.sleep(0.2)

Currently using the code above to attempt to transmit a simple power button press with the press of 'button'.

It runs the while loop without error, but nothing happens. I press the button and see the print statement, but nothing else. Where can I find the integers header, one, zero, and trail based on my TV. Documentation for the parameters is as follows:

header (int) – The length of header in microseconds

one (int) – The length of a one in microseconds

zero (int) – The length of a zero in microseconds

trail (int) – The length of the trail in microseconds, set to None to disable

I wanted to control a Sony camera and I looked at the Sony IRLib2 code for how to generate those for cpx-ir-shutter-remote.py. There's Samsung code in IRLib2 too which should be useful as a basis for your code.
