Port Driver

Port driver provides abstraction for accessing and controlling an entire port of your microcontroller.

Using Port driver you can configure a port as digital input or output, write to a port and read from a port.

To use this library

Header: #include "drv_port.h"

memake: MikroSDK.Driver


Before using other driver functions, user has to define driver context variable and initialize it, as shown below:

port_t port;

port_init( &port, PORT_A, 0xFFFF, GPIO_DIGITAL_OUTPUT );
Parameter Description
port Context variable
PORT_A Actual MCU port
0xFFFF Determines which pins will be configured; in this case all

Default state

Default state of the configured port is logical low, if pins are configured as digital output.

Writing to port

After configuring the port as digital output, you can use port_write() function for writing desired value to the port, as shown below:

uint16_t value = 0xAAAA;

port_write( &port, value );

Reading from port

After configuring the port as digital input, you can use port_read() function for reading from the port, as shown below:

uint16_t read_value;

read_value = port_read( &port );
