buenas otra vez,le regale un coche de esos que tienen el keystudio con un guante(esp32+mpu6050) para controlarlo y en el coche esp32+l298n, el codigo que me mandan es este :

Receptor

#include <esp_now.h>

#define IN1 13
#define IN2 12
#define IN3 14

const int PWMFreq = 1000;
const int PWMResolution = 8;
const int rightMotorPWMSpeedChannel = 4;
const int leftMotorPWMSpeedChannel = 5;

#define SIGNAL_TIMEOUT 1000
unsigned long lastRecvTime = 0;

struct PacketData {
  byte xAxisValue;
  byte yAxisValue;
  byte switchPressed;
};
PacketData receiverData;

bool throttleAndSteeringMode = false;

// Callback when ESP-NOW data is received

void OnDataRecv(const uint8_t *mac, const uint8_t *incomingData, int len) {
  if (len == 0) return;
  memcpy(&receiverData, incomingData, sizeof(receiverData));

  String inputData = "Values: " + String(receiverData.xAxisValue) + " " + String(receiverData.yAxisValue) + " " + String(receiverData.switchPressed);
  Serial.println(inputData);
  if (receiverData.switchPressed == true) {
    throttleAndSteeringMode = !throttleAndSteeringMode;
  }

  if (throttleAndSteeringMode) {
    throttleAndSteeringMovements();
  } else {
    simpleMovements();
  }
  lastRecvTime = millis();
}

void simpleMovements() {
  if (receiverData.yAxisValue <= 75) {
    rotateMotor(MAX_MOTOR_SPEED, MAX_MOTOR_SPEED);
  } else if (receiverData.yAxisValue >= 175) {
    rotateMotor(-MAX_MOTOR_SPEED, -MAX_MOTOR_SPEED);
  } else if (receiverData.xAxisValue >= 175) {
    rotateMotor(-MAX_MOTOR_SPEED, MAX_MOTOR_SPEED);
  }
  // Add more movement conditions as needed
}

pero me lanza el arduino ide este error :

Y si, tu código esta incompleto y al menos

throttleAndSteeringMovements();
rotateMotor(-MAX_MOTOR_SPEED, MAX_MOTOR_SPEED);

son procedimientos que no estan. Asi que busca de donde lo copiaste porque olvidaste parte del código.

es todo lo que dan, no hay mas codigo :( y no contestan, cierralo y borralo surbyte y perdon por las molestias

Ok pero falta algo, el código está incompleto.

Agrego:
En el siguiente link parece estar el código completo (no verifiqué si es el mismo que el tuyo)

Y un proyecto en GitHub que tiene el código completo, tal vez te sirva.
