21 @par Example Description | |
22 | |
23 This example shows how to configure the programmable voltage detector using | |
24 an external interrupt line. In this example, EXTI line 16 is configured to generate | |
25 an interrupt on each rising or falling edge of the PVD output signal (which | |
26 indicates that the Vdd voltage is below the PVD threshold). | |
27 In the interrupt routine a led connected to a specific GPIO pin is toggled every | |
28 time the voltage drops below or the target threshold. | |

40 | |
41 - This example runs on STM32F10x Connectivity line, High-Density, High-Density | |
42 Value line, Medium-Density, XL-Density, Medium-Density Value line, Low-Density | |
43 and Low-Density Value line Devices. | |
44 | |
45 - This example has been tested with STMicroelectronics STM32100E-EVAL (High-Density | |
46 Value line), STM32100B-EVAL (Medium-Density Value line), STM3210C-EVAL (Connectivity line), | |
47 STM3210E-EVAL (High-Density and XL-Density) and STM3210B-EVAL (Medium-Density) | |
48 evaluation boards and can be easily tailored to any other supported device | |
49 and development board. | |
50 To select the STMicroelectronics evaluation board used to run the example, | |
51 uncomment the corresponding line in stm32_eval.h file (under Utilities\STM32_EVAL) | |
52 | |
53 - STM32100E-EVAL Set-up | |
54 - Use LED1 led connected to PC.06 pin | |
55 | |
56 - STM32100B-EVAL Set-up | |
57 - Use LED1 led connected to PC.06 pin | |
58 | |

63 - Use LED1 led connected to PF.06 pin | |
64 | |
65 - STM3210B-EVAL Set-up | |
66 - Use LED1 led connected to PC.06 pin | |
67 | |
68 @note | |
69 - Use a variable DC power supply connected to the 3V3 input to the evaluation | |
70 board and dropping the voltage below 2.7V. | |
71 | |
72 @par How to use it ? | |
73 | |
74 In order to make the program work, you must do the following : | |
75 - Copy all source files from this example folder to the template folder under | |
76 Project\STM32F10x_StdPeriph_Template | |
77 - Open your preferred toolchain | |
78 - Rebuild all files and load your image into target memory | |
79 - Run the example in standalone mode (without debugger connection) | |
80 | |
81 @note | |
82 - Low-density Value line devices are STM32F100xx microcontrollers where the | |
83 Flash memory density ranges between 16 and 32 Kbytes. | |
84 - Low-density devices are STM32F101xx, STM32F102xx and STM32F103xx | |
85 microcontrollers where the Flash memory density ranges between 16 and 32 Kbytes. | |
86 - Medium-density Value line devices are STM32F100xx microcontrollers where | |
87 the Flash memory density ranges between 64 and 128 Kbytes. | |
88 - Medium-density devices are STM32F101xx, STM32F102xx and STM32F103xx | |
89 microcontrollers where the Flash memory density ranges between 64 and 128 Kbytes. | |
90 - High-density Value line devices are STM32F100xx microcontrollers where | |
91 the Flash memory density ranges between 256 and 512 Kbytes. | |
92 - High-density devices are STM32F101xx and STM32F103xx microcontrollers where | |
93 the Flash memory density ranges between 256 and 512 Kbytes. | |
94 - XL-density devices are STM32F101xx and STM32F103xx microcontrollers where | |
95 the Flash memory density ranges between 512 and 1024 Kbytes. | |
96 - Connectivity line devices are STM32F105xx and STM32F107xx microcontrollers. | |
