ESP32-S3 A1M8 Error

[lso2030]

I'm currently using ESP32 S3 N16R8 and A1M8 lidar
https://github.com/robopeak/rplidar_arduino
I'm using the above library and the program flash normally, but it doesn't work with the below error output on the serial monitor. Does anyone know how?

Code: Select all

#include <RPLidar.h>

RPLidar lidar;

// 핀 설정
#define RPLIDAR_MOTOR 1  // PWM 핀 (GPIO1)

// UART1 설정 (RPLidar 연결용)
#define RPLIDAR_UART_RX 18  // RPLidar TX 연결 (ESP32 RX)
#define RPLIDAR_UART_TX 17  // RPLidar RX 연결 (ESP32 TX)

// PWM 설정
#define PWM_FREQUENCY 20000  // 20kHz
#define PWM_RESOLUTION 8     // 8-bit (0~255)
#define PWM_DUTY_CYCLE 255   // 최대 듀티

void setup() {
  Serial.begin(115200);
  //Serial1.begin(115200, SERIAL_8N1, RPLIDAR_UART_RX, RPLIDAR_UART_TX);
  lidar.begin(Serial1);

  // PWM 초기화 (ESP32 Core 3.x API)
  ledcAttach(RPLIDAR_MOTOR, PWM_FREQUENCY, PWM_RESOLUTION);
  ledcWrite(RPLIDAR_MOTOR, PWM_DUTY_CYCLE);

  delay(100);
  lidar.startScan();
}

void loop() {
  //if (IS_OK(lidar.waitPoint())) {
    float distance = lidar.getCurrentPoint().distance;
    float angle    = lidar.getCurrentPoint().angle;
    byte quality   = lidar.getCurrentPoint().quality;

    if (distance > 0) {
      float radians = angle * PI / 180.0;
      float x = distance * cos(radians);
      float y = distance * sin(radians);

      Serial.print(x, 1);
      Serial.print(" ");
      Serial.println(y, 1);  // "x y" 출력
    }

  //}
  // else {
  //   Serial.println("NO\n");
  //   ledcWrite(RPLIDAR_MOTOR, 0);  // 모터 OFF

  //   rplidar_response_device_info_t info;
  //   if (IS_OK(lidar.getDeviceInfo(info, 100))) {
  //     lidar.startScan();
  //     ledcWrite(RPLIDAR_MOTOR, PWM_DUTY_CYCLE);  // 모터 재시작
  //     delay(1000);
  //   }
  // }
}

Hello,
Perhaps you did not post the error message here. I can see the code only.
