I need for my personal project counting pulse and direction with timer. With this code I can count only one direction. Any suggestion are welcome for correct code (this code is pretesting)

pulse count to PA_9 and direction input to PA_8

#include "mbed.h"
#include "stm32f4xx.h"
#include "stm32f4xx_hal_tim_ex.h"


TIM_HandleTypeDef timer;          
TIM_Base_InitTypeDef inizializza;
TIM_IC_InitTypeDef startclock;
TIM_ClockConfigTypeDef ClockConfig;
TIM_SlaveConfigTypeDef sSlaveConfigure;
TIM_MasterConfigTypeDef sMasterConfig;
TIM_Encoder_InitTypeDef hEncoder1;

int main(){
     GPIO_InitTypeDef GPIO_InitStruct;
        __TIM1_CLK_ENABLE();
        __GPIOA_CLK_ENABLE();
        GPIO_InitStruct.Pin = GPIO_PIN_8 | GPIO_PIN_9;
        GPIO_InitStruct.Mode = GPIO_MODE_AF_PP;
        GPIO_InitStruct.Pull = GPIO_PULLDOWN;
        GPIO_InitStruct.Speed = GPIO_SPEED_HIGH;
        GPIO_InitStruct.Alternate = GPIO_AF1_TIM1;
        HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);

    timer.Instance = TIM1;
    timer.Init.Period = 0xffff;
    timer.Init.Prescaler = 0;
    timer.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1;
    timer.Init.CounterMode = TIM_COUNTERMODE_CENTERALIGNED3;
    timer.Init.RepetitionCounter = 0;

    HAL_TIM_Base_Init(&timer);


  sSlaveConfigure.SlaveMode = TIM_SLAVEMODE_DISABLE;
  HAL_TIM_SlaveConfigSynchronization(&timer, &sSlaveConfigure);

  sMasterConfig.MasterOutputTrigger = TIM_TRGO_UPDATE;
  sMasterConfig.MasterSlaveMode = TIM_MASTERSLAVEMODE_DISABLE;
  HAL_TIMEx_MasterConfigSynchronization(&timer, &sMasterConfig);

  ClockConfig.ClockFilter = 0;
  ClockConfig.ClockPolarity = TIM_CLOCKPOLARITY_RISING;
  ClockConfig.ClockPrescaler = TIM_CLOCKPRESCALER_DIV1;
  ClockConfig.ClockSource = TIM_CLOCKSOURCE_TI2; 
  HAL_TIM_ConfigClockSource( &timer, &ClockConfig );
   TIM1->CR1 |= TIM_CR1_ARPE; // autoreload on
   //TIM1->CR1 |= TIM_CR1_CEN;
   TIM1->CR1 = 1;  // enable timer

 while (1) {
        int16_t count1;
        count1=TIM1->CNT; 

        printf("%d\r\n", count1);
        wait(1.0);

 };
}
