<> | 144:ef7eb2e8f9f7 | 16 | ============================================================================== |
<> | 144:ef7eb2e8f9f7 | 17 | [..] |
<> | 144:ef7eb2e8f9f7 | 18 | (+) Each port bit of the general-purpose I/O (GPIO) ports can be individually |
<> | 144:ef7eb2e8f9f7 | 19 | configured by software in several modes: |
<> | 144:ef7eb2e8f9f7 | 20 | (++) Input mode |
<> | 144:ef7eb2e8f9f7 | 21 | (++) Analog mode |
<> | 144:ef7eb2e8f9f7 | 22 | (++) Output mode |
<> | 144:ef7eb2e8f9f7 | 23 | (++) Alternate function mode |
<> | 144:ef7eb2e8f9f7 | 24 | (++) External interrupt/event lines |
<> | 144:ef7eb2e8f9f7 | 25 | |
<> | 144:ef7eb2e8f9f7 | 26 | (+) During and just after reset, the alternate functions and external interrupt |
<> | 144:ef7eb2e8f9f7 | 27 | lines are not active and the I/O ports are configured in input floating mode. |
<> | 144:ef7eb2e8f9f7 | 28 | |
<> | 144:ef7eb2e8f9f7 | 29 | (+) All GPIO pins have weak internal pull-up and pull-down resistors, which can be |
<> | 144:ef7eb2e8f9f7 | 30 | activated or not. |
<> | 144:ef7eb2e8f9f7 | 31 | |
<> | 144:ef7eb2e8f9f7 | 32 | (+) In Output or Alternate mode, each IO can be configured on open-drain or push-pull |
<> | 144:ef7eb2e8f9f7 | 33 | type and the IO speed can be selected depending on the VDD value. |
<> | 144:ef7eb2e8f9f7 | 34 | |
<> | 144:ef7eb2e8f9f7 | 35 | (+) The microcontroller IO pins are connected to onboard peripherals/modules through a |
<> | 144:ef7eb2e8f9f7 | 36 | multiplexer that allows only one peripheral alternate function (AF) connected |
<> | 144:ef7eb2e8f9f7 | 37 | to an IO pin at a time. In this way, there can be no conflict between peripherals |
<> | 144:ef7eb2e8f9f7 | 38 | sharing the same IO pin. |
<> | 144:ef7eb2e8f9f7 | 39 | |
<> | 144:ef7eb2e8f9f7 | 40 | (+) All ports have external interrupt/event capability. To use external interrupt |
<> | 144:ef7eb2e8f9f7 | 41 | lines, the port must be configured in input mode. All available GPIO pins are |
<> | 144:ef7eb2e8f9f7 | 42 | connected to the 16 external interrupt/event lines from EXTI0 to EXTI15. |
<> | 144:ef7eb2e8f9f7 | 43 | |
<> | 144:ef7eb2e8f9f7 | 44 | (+) The external interrupt/event controller consists of up to 23 edge detectors |
<> | 144:ef7eb2e8f9f7 | 45 | (16 lines are connected to GPIO) for generating event/interrupt requests (each |
<> | 144:ef7eb2e8f9f7 | 46 | input line can be independently configured to select the type (interrupt or event) |
<> | 144:ef7eb2e8f9f7 | 47 | and the corresponding trigger event (rising or falling or both). Each line can |
<> | 144:ef7eb2e8f9f7 | 48 | also be masked independently. |
<> | 144:ef7eb2e8f9f7 | 49 | |
<> | 144:ef7eb2e8f9f7 | 50 | ##### How to use this driver ##### |

<> | 144:ef7eb2e8f9f7 | 63 | (++) Analog mode is required when a pin is to be used as ADC channel |
