Infrared not functioning

[2lag]

I basically pasted the code with a few changes, I'm currently working on a five-screen software for my M5StickC-Plus that I want to put out when I'm done.

Does anybody have working suggestions or code for working infrared? This is what I currently have :

#include "M5_ScreenFive.h"
#include "M5_Rotate.h"
#include "includes.h"

const int ir_recv_pin = 33;
const int ir_send_pin = 9;
int last_recv_v = 0;
int curr_recv_v = 0;

void setup_IR() {
  pinMode( ir_recv_pin, INPUT );
  pinMode( ir_send_pin, OUTPUT );
}

void screen_three_loop( int &cursor_x, int &cursor_y ) {
  unsigned char ir_code = 0;
  while( true ) {
    m5.update();

    if( m5.BtnA.wasReleased() ) return;

    m5.imu.getAhrsData( &pitch, &roll, &yaw );

    if( abs( roll - proll ) > 10 ) {
      rotate_screen( cursor_x, cursor_y );
      proll = roll;
    }

    m5.lcd.setCursor( cursor_x, cursor_y );
    m5.lcd.setTextSize(2);
    m5.lcd.print( "___Infra___" );

    if( m5.BtnB.isPressed() ) {
      digitalWrite( ir_send_pin, ir_code );
      m5.lcd.setCursor( cursor_x, 80 );
      m5.lcd.print( "Sending IR" );
      ir_code++;
      m5.lcd.fillRect( cursor_x, 30, 210, 210, BLACK );
    }

    m5.lcd.setCursor( cursor_x, 30 );
    m5.lcd.printf( "Send : 0x%02X", ir_code );

    m5.lcd.setCursor( cursor_x, 50 );
    curr_recv_v = digitalRead( ir_recv_pin );
    if( curr_recv_v != last_recv_v ) {
      m5.lcd.fillRect( cursor_x, 50, 210, 180, BLACK );
      m5.lcd.printf( "Recv : 0x%02X", digitalRead( ir_recv_pin ) );
      last_recv_v = curr_recv_v;
    }

    delay( 25 );
  }
  return;
}

Edit : Got output working by changing send pin from 32 to 9, now finding a bug with the speed it can send so I'm going to fix that real quick, still not sure what to do about receiving though.

I can see the example you used is this one https://github.com/m5stack/M5StickC-Plus/blob/8fc1c981b503c460b1e2ff457d5182780834ae69/examples/Unit/IR/IR.ino#L19-L20

Actually, this is the actual example for external devices

The CPlus device only has infrared transmission, if you delete the reception in the above example, there should be no problem.
