Common libraries

The common libraries

• provide a light hardware abstraction layer to manage the GPIO, UART, SPI and I²C peripherals.

• share utilities across the different libraries;

• expose the parameters to set diverse options;

• define the structure and list the pre-configured main controller boards;

• list the supported screen constants.

Configure

Main code

// SDK and configuration
#include "PDLS_Common.h"

The pre-processor statement calls the common libraries. The PDLS_Common umbrella header file includes the SDK with the peripherals library, the utilities, the constants and the configuration.

Use

Main code

hV_HAL_begin();

hV_HAL_begin()

proceeds with the general initialisation. It configures and starts the peripherals GPIO, UART, SPI, and I²C if needed.

Terminate

Main code

hV_HAL_exit();

hV_HAL_exit()

displays the code value, and enters an endless loop for micro-controllers.
