STM8S105C6 - How to use and configure clock to control and accelerate an PMDC motor using 3 timers.

[RBusa.1]

Hello, I need to make this stm8s105c6 to control an 3.0 V PMDC motor using timers and microcontroller's clock. Also, I need to use pwm and this driver: EV - VNH7040AY. Timers:

• timer 1 -> accelerate to nominal power
• timer 2 -> nominal power
• timer 3 -> decelerate to 0

I am totaly new and idk how to declare / write complicated sequences. I created an prototype with arduino and L298N. It is possible to translate it to STVD? Any suggestions? Thanks for attention!

Source code Arduino:

// PWM PROTOTYPE - DC MOTOR CONTROL USING ARDUINO UNO AND L298N MOTOR DRIVER - BUSARU ROBERT - CRISTIAN
 
//Initializing  pwm pin
int ena = 10;  // pwm pin
int in1 = 2; // motor direction
int in2 = 4; // motor direction
 
//Initializing timers;
int tim1 = 3000; // acceleration time
int pwm1 = 255;
 
 
int tim2 = tim1 + 2000; // nominal power time
int pwm2 = 255;
 
int tim3 = tim2 + 3000; // deceleration time
 
 
unsigned long myTime; // clock
 
 
 
void setup() {
  //Declaring pwm pin as output
  pinMode(ena, OUTPUT);
  pinMode(in1, OUTPUT);
  pinMode(in2, OUTPUT);
  //Declaring Serial Monitor to see timers and what happen there;
  Serial.begin(9600);
}
 
 
void phase1() {
  myTime = millis();
  Serial.println(myTime);
 
 
}
 
 
void loop() {
 
  myTime = millis();
  Serial.println(myTime);
  if (myTime <= tim1) {                                                 //TIM 1 -> accelerating time
    // currencyTime = myTime;
    for (int i = 0; i < pwm1; i++) {
      analogWrite(ena, i);
    }
    Serial.print("Accelerare: ");
  } else if (myTime > tim1 && myTime < tim2) {                          //TIM 2 -> nominal power time
    // currencyTime = myTime;
    analogWrite(ena, pwm2);
    Serial.print("Nominal: ");
  } else if (myTime >= tim3 && myTime <= tim3 + tim2 + tim1) {          //TIM3 -> deceleration time
    for (int i = pwm2; i >= 0; i--) {
      analogWrite(ena, i);
      if (i == 0 && myTime > tim1 + tim2 + tim3) {
        analogWrite(ena, 0);
        myTime = 0;
      }
    }
    Serial.print("Decelerare: ");
  }
 
 
  digitalWrite(in1, HIGH);
  digitalWrite(in2, LOW);
