21 @par Example Description
22
23 This example shows how to configure external interrupt lines.
24 In this example, 2 EXTI lines (EXTI0 and EXTI8 or EXTI9) are configured
25 to generate an interrupt on each rising or falling edge. In the interrupt routine
26 a led connected to a specific GPIO pin is toggled.
27
28 In this example:
29 - EXTI0 is mapped to PA.00
30 - EXTI8 is mapped to PG.08
31 - EXTI9 is mapped to PB.09
32
33 After EXTI configuration, a software interrupt is generated on the EXTI0 toggles LED1.
34 After that,
35 when rising edge is detected on EXTI0, LED1 toggles
36 when falling edge is detected on EXTI8, LED2 toggles
37 when falling edge is detected on EXTI9, LED2 toggles
38
39
40 If any STM3210XX-EVAL is used,
41 when Wakeup push-button is pressed, LED1 toggles
42 when Key push-button is pressed, LED2 toggles
43
44 In this example, EXTI0_Config() function can be substituted by
45 STM_EVAL_PBInit(Button_WAKEUP, Mode_EXTI) and EXTI9_5_Config() by
46 STM_EVAL_PBInit(Button_KEY, Mode_EXTI) provided in the STM3210XX-EVAL driver.

59 - This example runs on STM32F10x Connectivity line, High-Density, High-Density
60 Value line, Medium-Density, XL-Density, Medium-Density Value line, Low-Density
61 and Low-Density Value line Devices.
62
63 - This example has been tested with STMicroelectronics STM32100E-EVAL (High-Density
64 Value line), STM32100B-EVAL (Medium-Density Value line), STM3210C-EVAL
65 (Connectivity line), STM3210E-EVAL (High-Density and XL-Density) and STM3210B-EVAL
66 (Medium-Density) evaluation boards and can be easily tailored to any other
67 supported device and development board.
68 To select the STMicroelectronics evaluation board used to run the example,
69 uncomment the corresponding line in stm32_eval.h file (under Utilities\STM32_EVAL)
