Code transmission not same as remote

[No1089]

Hi,

I'm having some weird problems while trying to send out a remote code. I'm using the itsybitsy M4 express.

I have used two configurations to set up the header: 1) This produces an output similar to the Sony remote on the logic analyser. encoder = adafruit_irremote.GenericTransmit(header=[2400, 550], zero=[1150, 630], one=[630, 550], trail=0) 2) This is more alligned with the Sony remote's supposed header. encoder = adafruit_irremote.GenericTransmit(header=[2400, 550], zero=[630, 1150], one=[550, 630], trail=0)

When reading my sony remote's code I receive the following: Heard 25 Pulses: [2455, 544, 1225, 554, 637, 546, 1250, 542, 670, 525, 1241, 551, 650, 552, 648, 540, 1243, 549, 653, 542, 649, 546, 645, 549, 667] length: 25 new length: 24 evenbins: [[547, 12]] oddbins: [[1241, 4], [657, 8]] evenbins: [[547, 12]] oddbins: [[1241, 4], [657, 8]] outliers: [] Pulses: [1225, 637, 1250, 670, 1241, 650, 648, 1243, 653, 649, 645, 667] & Bins: [[1241, 4], [657, 8]] Space: 1241 Mark: 657 12 [False, True, False, True, False, True, True, False, True, True, True, True] Decoded: [86, 15] When I transmit the same code on the M4 I receive the following: Header 1: Heard 34 Pulses: [2463, 495, 1207, 606, 674, 470, 1189, 595, 686, 498, 1179, 586, 699, 487, 677, 509, 1233, 576, 1149, 600, 1202, 590, 1202, 563, 1176, 617, 679, 507, 674, 512, 679, 481, 700, 486] length: 34 new length: 32 evenbins: [[1186, 8], [689, 8]] oddbins: [[496, 16]] evenbins: [[1186, 8], [689, 8]] oddbins: [[496, 16]] outliers: [] Pulses: [1207, 674, 1189, 686, 1179, 699, 677, 1233, 1149, 1202, 1202, 1176, 679, 674, 679, 700] & Bins: [[1186, 8], [689, 8]] Space: 1186 Mark: 689 16 [False, True, False, True, False, True, True, False, False, False, False, False, True, True, True, True] Decoded: [86, 15] Header 2: Heard 34 Pulses: [2471, 507, 653, 1114, 572, 614, 683, 1111, 596, 563, 671, 1122, 596, 591, 600, 586, 647, 1119, 651, 1142, 682, 1110, 650, 1117, 675, 1117, 601, 585, 595, 565, 574, 613, 599, 587] length: 34 new length: 32 evenbins: [[596, 16]] oddbins: [[1117, 8], [590, 8]] evenbins: [[596, 16]] oddbins: [[1117, 8], [590, 8]] outliers: [] Pulses: [1114, 614, 1111, 563, 1122, 591, 586, 1119, 1142, 1110, 1117, 1117, 585, 565, 613, 587] & Bins: [[1117, 8], [590, 8]] Space: 1117 Mark: 590 16 [False, True, False, True, False, True, True, False, False, False, False, False, True, True, True, True] Decoded: [86, 15]

The code is appearing, but between the two bytes some extra data is added. Is there a way to bypass this/transmit the raw pulses?

I'm a bit stuck and having no luck with the IRLib2 on Arduino - it's not allowing me to send codes out - the pin definition is not entirely clear and SAMD51 is barely supported.

I prefer to use Circuitpython since it allows much easier remote debugging.

the Sony encoder/decoder isnt that heavily tested - since the samd51 has tons of RAM can you just send out the full array, see if the issue is in the encoder or the IR transmitter section?

I'd love to do exactly that, but not sure where/how to implement it.

this guide has some example code that you may be able to use! https://learn.adafruit.com/circuitpython-tv-zapper-with-circuit-playground-express

Thank you. I'll give it a go. Reverted to Arduino, since the deadline is tomorrow, but I have further use for this.

I got it working! Thanks @ladyada!

This is the code I used:

`import array import time import adafruit_irremote import pulseio import board import digitalio

button = digitalio.DigitalInOut(board.A3) button.direction = digitalio.Direction.INPUT button.pull = digitalio.Pull.UP

pwm = pulseio.PWMOut(board.D5, frequency=38000, duty_cycle=2 ** 15, variable_frequency=True) pulse = pulseio.PulseOut(pwm) pulses = [2452, 527, 1238, 553, 662, 527, 1264, 527, 662, 528, 1263, 527, 663, 527, 666, 528, 1259, 527, 667, 527, 636, 553, 667, 527, 662]

while True: if not button.value: print("IR signal sent!") pulse.send(array.array('H', pulses)) time.sleep(0.1) pulse.send(array.array('H', pulses)) time.sleep(0.1) pulse.send(array.array('H', pulses)) time.sleep(0.1)`

congrats :)
