In the SysTick interrupt handler, the LED1 is +toggled, this is used to indicate whether the MCU is in STANDBY or RUN mode. + +When a falling edge is detected on the EXTI line an interrupt is generated. In the +EXTI handler routine the RTC is configured to generate an Alarm event in 3 second +then the system enters STANDBY mode causing the LED1 to stop toggling. +A rising edge on WKUP pin or an external RESET will wake-up the system from +STANDBY. If within 3 second neither rising edge on WKUP pin nor external RESET +are generated, the RTC Alarm will wake-up the system. + +After wake-up from STANDBY mode, program execution restarts in the same way as after +a RESET, the LED1 restarts toggling, LED2 is turned on and the RTC configuration +(clock source, enable, prescaler,...) is kept. +As result there is no need to configure the RTC. + +Two leds LED1 and LED2 are used to monitor the system state as following: + - LED1 toggling: system in RUN mode + - LED1 off / LED2 off: system in STANDBY mode + - LED2 on: system resumed from STANDBY mode + +@par Directory contents + + - PWR/STANDBY/stm32f10x_conf.h Library Configuration file + - PWR/STANDBY/stm32f10x_it.c Interrupt handlers + - PWR/STANDBY/stm32f10x_it.h Header for stm32f10x_it.c + - PWR/STANDBY/main.c Main program + - PWR/STANDBY/system_stm32f10x.c STM32F10x system source file + +@par Hardware and Software environment + + - This example runs on STM32F10x Connectivity line, High-Density, High-Density + Value line, Medium-Density, XL-Density, Medium-Density Value line, Low-Density + and Low-Density Value line Devices. + + - This example has been tested with STMicroelectronics STM32100E-EVAL (High-Density + Value line), STM32100B-EVAL (Medium-Density Value line), STM3210C-EVAL (Connectivity line), + STM3210E-EVAL (High-Density and XL-Density) and STM3210B-EVAL (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 stm32_eval.h file (under Utilities\STM32_EVAL) + + - STM32100E-EVAL Set-up + - Use LED1 and LED2 connected respectively to PF.06 and PF.07 pins + - Use the Key push-button connected to pin PG.08 (EXTI Line8). + - Use the Wakeup push-button connected to WKUP(PA.00) pin + + - STM32100B-EVAL Set-up + - Use LED1 and LED2 connected respectively to PC.06 and PC.07 pins + - Use the Key push-button connected to pin PB.09 (EXTI Line9). + - Use the Wakeup push-button connected to WKUP(PA.00) pin + + - STM3210C-EVAL Set-up + - Use LED1 and LED2 connected respectively to PD.07 and PD.13 pins + - Use the Key push-button connected to pin PB.09 (EXTI Line9). + - Use the Wakeup push-button connected to WKUP(PA.00) pin, make sure + that jumper JP14 is in position 2-3. + + - STM3210E-EVAL Set-up + - Use LED1 and LED2 connected respectively to PF.06 and PF.07 pins + - Use the Key push-button connected to pin PG.08 (EXTI Line8). + - Use the Wakeup push-button connected to WKUP(PA.00) pin + @note the jumper JP4 must be not fit to be able to use the Wakeup push-button + + - STM3210B-EVAL Set-up + - Use LED1 and LED2 connected respectively to PC.06 and PC.07 pins + - Use the Key push-button connected to pin PB.09 (EXTI Line9). + - Use the Wakeup push-button connected to WKUP(PA.00) pin + +@note For power consumption measurement in STANDBY mode, you have to replace + jumper JP9 in the STM3210B-EVAL board, JP12 in the STM3210E-EVAL or + JP23 (position 1-2) in the STM3210C-EVAL board by an amperemeter. + + +@par How to use it ? + +In order to make the program work, you must do the following : + - Copy all source files from this example folder to the template folder under + Project\STM32F10x_StdPeriph_Template + - Open your preferred toolchain + - Rebuild all files and load your image into target memory + - Run the example in standalone mode (without debugger connection) + +@note + - Low-density Value line devices are STM32F100xx microcontrollers where the + Flash memory density ranges between 16 and 32 Kbytes. + - Low-density devices are STM32F101xx, STM32F102xx and STM32F103xx + microcontrollers where the Flash memory density ranges between 16 and 32 Kbytes. + - Medium-density Value line devices are STM32F100xx microcontrollers where + the Flash memory density ranges between 64 and 128 Kbytes. + - Medium-density devices are STM32F101xx, STM32F102xx and STM32F103xx + microcontrollers where the Flash memory density ranges between 64 and 128 Kbytes. + - High-density Value line devices are STM32F100xx microcontrollers where + the Flash memory density ranges between 256 and 512 Kbytes. + - High-density devices are STM32F101xx and STM32F103xx microcontrollers where + the Flash memory density ranges between 256 and 512 Kbytes. + - XL-density devices are STM32F101xx and STM32F103xx microcontrollers where + the Flash memory density ranges between 512 and 1024 Kbytes. + - Connectivity line devices are STM32F105xx and STM32F107xx microcontrollers. + + *
