Arduino l293d shield with esp32, library not compiling

[rayan_ahmad]

The adafruit motor shield library won't compile for esp32 and i only want to control to motors, out of 4 ports, the library example it self reurns an erorr, /storage/emulated/0/ArduinoDroid/userlibraries/Adafruit_Motor_Shield_library/AFMotor.h:156:47: error: 'DC_MOTOR_PWM_RATE' was not declared in this scope
I also dont understand why many other pins like en , and ? ? Latch are used, still will wire it tho

Me too.

Post your current sketch to see how we can help.

If you had bothered to read the how to get the best from the forum post you would know that we can give best help if you properly post well formatted code, a schematic, links to any libraries that don't come with the IDE.

#include <AFMotor.h>

AF_DCMotor motor(4);

void setup() {
  Serial.begin(9600);           // set up Serial library at 9600 bps
  Serial.println("Motor test!");

  // turn on motor
  motor.setSpeed(200);
 
  motor.run(RELEASE);
}

void loop() {
  uint8_t i;
  
  Serial.print("tick");
  
  motor.run(FORWARD);
  for (i=0; i<255; i++) {
    motor.setSpeed(i);  
    delay(10);
 }
 
  for (i=255; i!=0; i--) {
    motor.setSpeed(i);  
    delay(10);
 }
  
  Serial.print("tock");

  motor.run(BACKWARD);
  for (i=0; i<255; i++) {
    motor.setSpeed(i);  
    delay(10);
 }
 
  for (i=255; i!=0; i--) {
    motor.setSpeed(i);  
    delay(10);
 }
  

  Serial.print("tech");
  motor.run(RELEASE);
  delay(1000);
}

This is the adafruit library example, i have tested it with an arduino and compiled successfully and worked

This Motor Driver Board is specifically designed for arduino UNO and it just goes over the UNO Board.

For ESP32 Board, you may use the L298 Motor Driver Board and write the codes to control the Motors based on te following truth Table:
