Digital In Driver¶
The digital in driver provides abstraction for accessing GPIO individual pins as digital input. It provides functionality to read state of a digital input pin.
To use this library
Header: #include "drv_digital_in.h"
memake: MikroSDK.Driver
Initialization¶
Before using other driver functions, user needs to define driver context variable and initialize it, as shown in the example below:
digital_in_t in_pin;
digital_in_init(&out_in, PA12);
First parameter is the address of driver context structure, and second parameter
is the name of the pin that will be configured as digital input. After the
initialization, in_pin variable will be our handle for accessing the
configured pin.
Reading pin state¶
For reading pin state, the driver provides a single function digital_in_read.
Basic usage is shown below:
digital_in_data_t state;
state = digital_in_read(&in_pin);
