Using RTC in new MDK uVision5

Hello,
I'm trying use new uVision5 and i don't know where is pariphery library for RTC and how it use. Can anyone help me with this?

Thank You

I have STM32F103RBT6. I'm searching library, where is structure for initialize RTC periphery. In this .c and .h are declared functions for set RTC, read RTC and others functions for work with RTC. Same to GPIO i can't search .c and .h files, where is structture for initialize concrete pins as (IN, OUT, AFIO, speed, etc.). This method was used in older versions MDK-ARM uVision 4.xx.
This files have names for example: stm32f10x_rtc.h + stm32f10x_rtc.c, stm32f10x_gpio.h + stm32f10x_gpio.c.

I don't have any code because i don't know how initialize each periphery without these files. Most important files which i can't search is for RCC for set internal clock for AHB, APB1, APB2. This "periphery" i can set in older versions that:

void RCC_Configuration(void)
{
ErrorStatus HSEStartUpStatus;
  RCC_DeInit();
  RCC_HSEConfig(RCC_HSE_ON);                                                                    // Enable HSE
  HSEStartUpStatus = RCC_WaitForHSEStartUp();                                   // Wait till HSE is ready
  if(HSEStartUpStatus == SUCCESS)
    {
     FLASH_PrefetchBufferCmd(FLASH_PrefetchBuffer_Enable);              // Enable Prefetch Buffer
     FLASH_SetLatency(FLASH_Latency_2);                                                 // Flash 2 wait state
     RCC_HCLKConfig(RCC_SYSCLK_Div1);                                                   // HCLK = SYSCLK 72MHz
     RCC_PCLK2Config(RCC_HCLK_Div1);                                                    // PCLK2 = HCLK 72MHz
     RCC_PCLK1Config(RCC_HCLK_Div2);                                                    // PCLK1 = HCLK/2 36MHz
     RCC_PLLConfig(RCC_PLLSource_HSE_Div1, RCC_PLLMul_9);               // PLLCLK = 8MHz * 9 = 72 MHz
     RCC_PLLCmd(ENABLE);                                                                                // Enable PLL
     while(RCC_GetFlagStatus(RCC_FLAG_PLLRDY) == RESET);                // Wait till PLL is ready
     RCC_SYSCLKConfig(RCC_SYSCLKSource_PLLCLK);                                 // Select PLL as system clock source
     while(RCC_GetSYSCLKSource() != 0x08);                                              // Wait till PLL is used as system clock source
    }
  // Enable GPIOA, GPIOB, GPIOC, GPIOD, GPIOE, GPIOF, GPIOG and AFIO clocks
  RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOA | RCC_APB2Periph_GPIOB |RCC_APB2Periph_GPIOC
         | RCC_APB2Periph_GPIOD | RCC_APB2Periph_GPIOE | RCC_APB2Periph_GPIOF | RCC_APB2Periph_GPIOG
         | RCC_APB2Periph_AFIO, ENABLE);
}

For GPIOs that:

void GPIO_Configuration(void)
{

  GPIO_InitStructure.GPIO_Pin = GPIO_Pin_2;
  GPIO_InitStructure.GPIO_Speed = GPIO_Speed_10MHz;
  GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
  GPIO_Init(GPIOA, &GPIO_InitStructure);
}

If i need set RTC, i can use function of stm32f10x_rtc.h declared in stm32f10x_rtc.c that:

RTC_SetCounter(1336942091);

If i need set one GPIO as '1' i use:

GPIO_SetBits(GPIOA, GPIO_Pin_3);

This all functions i using in older versions and now i version 5 i don't know where are .c and .h files. Can anyone explain me how it works in version 5? How set RTC or any GPIO pin and initialize periphery?

Thank you
Jan

The code you show is from the ST Standard Peripheral Library. It is from ST, not Keil - it has nothing specifically to do with Keil or uVision or MDK.
