control servo without the librery

hello,
i try to build an rc car using arduinos and 433Mhz module for the direction the car use a servomotor, in the code i used radiohead RH_ASK.h for the 433 modules and Servo.h to drive the servo, after compiling the ide is show an error code after i searched on google i found that the RH_ASK.h and Servo.h have a conflict, they both use timer1 so i desired to not use servo.h here is my code :

#include <RH_ASK.h>
#include <SPI.h> 
RH_ASK driver;

void setup()
{
    Serial.begin(9600);  // Debugging only
    if (!driver.init())
         Serial.println("init failed");
         pinMode(9, OUTPUT);
        
}

void loop()
{
int b;
uint8_t buf[RH_ASK_MAX_MESSAGE_LEN];
  uint8_t buflen = sizeof(buf);
   if (driver.recv(buf, &buflen))
          {
          if((int)buf[1]==66)
              {
                b=(int)buf[0];
                d=map(b, 0, 255, 120, 180);       
                Serial.println(d*10);

              } 
}  

             digitalWrite(9, HIGH);
             delayMicroseconds(d*10);
             digitalWrite(9, LOW);
             delayMicroseconds(20000-d*10);
  
}

the receiver work fine, i get the correct value on the serial monitor but the servo go crazy, and when i test the servo code alone it work :

void setup(){
pinMode(9, OUTPUT);
void loop(){ 
             int d=150;
             digitalWrite(9, HIGH);
             delayMicroseconds(d*10);
             digitalWrite(9, LOW);
             delayMicroseconds(20000-d*10);
}

the servo goes to 90 deg
can someone please help me ?

There is an alternative servo library that uses timer 2. It is the ServoTimer2 library.

thank you man i will try it and feedback

it worked perfectly, thank you another time.
