As an application example, it demonstrates how to setup the RTC peripheral, in terms of prescaler and interrupts, to be used to keep time and to generate Second interrupt. The Low Speed External (LSE) clock is used as RTC clock source. The RTC clock can be output on the Tamper pin (PC.13). To enable this functionality, uncomment the corresponding line: #define RTCClockOutput_Enable in the main.c file. The RTC is in the backup (BKP) domain, still powered by VBAT when VDD is switched off, so the RTC configuration is not lost if a battery is connected to the VBAT pin. A key value is written in backup data register1 (BKP_DR1) to indicate if the RTC is already configured. The program behaves as follows: 1. After startup the program checks the backup data register1 value: - register1 value not correct: (BKP_DR1 value is not correct or has not yet been programmed when the program is executed for the first time) the RTC is configured and the user is asked to set the time (entered on HyperTerminal). - register1 value correct: this means that the RTC is configured and the time is displayed on HyperTerminal. 2. When an External Reset occurs the BKP domain is not reset and the RTC configuration is not lost. 3. When power on reset occurs: - If a battery is connected to the VBAT pin: the BKP domain is not reset and the RTC configuration is not lost. - If no battery is connected to the VBAT pin: the BKP domain is reset and the RTC configuration is lost. In the RTC interrupt service routine, a specific GPIO pin toggles every 1 s. The C library printf function is retargeted to the USART1, that is, the printf message is output to the HyperTerminal using USART1. @par Directory contents - RTC/Calendar/platform_config.h Evaluation board specific configuration file - RTC/Calendar/stm32f10x_conf.h Library Configuration file - RTC/Calendar/stm32f10x_it.c Interrupt handlers - RTC/Calendar/stm32f10x_it.h Header for stm32f10x_it.c - RTC/Calendar/main.c Main program @par Hardware and Software environment - This example runs on STM32F10x High-Density, STM32F10x Medium-Density and STM32F10x Low-Density Devices. - This example has been tested with STMicroelectronics STM3210E-EVAL (STM32F10x High-Density) and STM3210B-EVAL (STM32F10x Medium-Density) evaluation boards and can be easily tailored to any other supported device and development board. To select the STMicroelectronics evaluation board used to run the example, uncomment the corresponding line in platform_config.h file. - STM3210E-EVAL Set-up - Use LD1 led connected to PF.06. - The USART1 signals (Rx, Tx) must be connected to a DB9 connector using a RS232 transceiver. - Connect a null-modem female/female RS232 cable between the DB9 connector (CN12 on STM3210B-EVAL board) and PC serial port. - Hyperterminal configuration: - Word Length = 8 Bits - One Stop Bit - No parity - BaudRate = 115200 baud - flow control: None - Connect a 3V battery on Vbat pin (already mounted on STM3210E-EVAL board) - STM3210B-EVAL Set-up - Use LD1 led connected to PC.06. - The USART1 signals (Rx, Tx) must be connected to a DB9 connector using a RS232 transceiver. - Connect a null-modem female/female RS232 cable between the DB9 connector (CN6 on STM3210B-EVAL board) and PC serial port. - Hyperterminal configuration: - Word Length = 8 Bits - One Stop Bit - No parity - BaudRate = 115200 baud - flow control: None - Connect a 3V battery on Vbat pin (already mounted on STM3210B-EVAL board) @par How to use it ? In order to make the program work, you must do the following : - Create a project and setup all project configuration - Add the required Library files : - stm32f10x_gpio.c - stm32f10x_rcc.c - stm32f10x_rtc.c - stm32f10x_bkp.c - stm32f10x_pwr.c - misc.c - stm32f10x_usart.c - system_stm32f10x.c - Edit stm32f10x.h file to select the device you are working on. @b Tip: You can tailor the provided project template to run this example, for more details please refer to "stm32f10x_stdperiph_lib_um.chm" user manual; select "Peripheral Examples" then follow the instructions provided in "How to proceed" section. - Link all compiled files and load your image into target memory - Run the example @note - Low-density devices are STM32F101xx and STM32F103xx microcontrollers where the Flash memory density ranges between 16 and 32 Kbytes. - Medium-density devices are STM32F101xx and STM32F103xx microcontrollers where the Flash memory density ranges between 32 and 128 Kbytes. - High-density devices are STM32F101xx and STM32F103xx microcontrollers where the Flash memory density ranges between 256 and 512 Kbytes. * <h3><center>&copy; COPYRIGHT 2009 STMicroelectronics</center></h3> */
