should this be digitalio.Pull.UP to match essentials guide, etc? would require changing the conditional in the loop

The buttons are backwards on the CPX. So either this or the loop will be backwards for CPX or an external button. We'll leave it as CPX for now and consider changing it if we receive a bunch of feedback.


# Create a 'pulseio' output, to send infrared signals on the IR transmitter @ 38KHz
pwm = pulseio.PWMOut(board.IR_TX, frequency=38000, duty_cycle=2 ** 15)
pulseout = pulseio.PulseOut(pwm)
# Create an encoder that will take numbers and turn them into NEC IR pulses
encoder = adafruit_irremote.GenericTransmit(header=[9500, 4500], one=[550, 550],
zero=[550, 1700], trail=0)

add a print("sending code") or something here so there's indication in REPL

Sounds good! Adding now.

encoder.transmit(pulseout, [255, 2, 255, 0])
time.sleep(0.2)
