# sam-lib

The `sam-lib` C library provides an API for controlling peripherals of

microcontrollers. Supported devices include microcontrollers from the

Microchip (Atmel) AT91 family, specifically SAM3N, SAM3S, SAM4N, and SAM4S

chips. Supported standard peripherals include SUPC, RSTC, WDT, PMC, EEFC,

UART, USART, PIO, TWI, ADC, DACC, SPI, TC, and various hardware components

connected to the microcontroller, such as buttons, LEDs, LEDUI, IO extenders

(shift registers), and more.

## Library Features

- Standardized API (designed for the AZTech framework).

- Implementation of low-level serial communication protocols.

- Designed for real-time applications with multitasking support

  (dependent on FreeRTOS).

- Efficient interrupt handling.

- Utilizes DMA where applicable.

- Instances of communication peripherals are represented as C structures

  with synchronous (blocking) `read()` and `write()` operations.

- Supports low-power modes of the microcontroller. Peripheral blocks are

  turned off when entering sleep mode.
