AVR32 - PDCA Driver - PDCA Example Documentation

Introduction

This documents data structures, functions, variables, defines, enums, and typedefs in the software for the PDCA driver.

The Peripheral DMA controller (PDCA) transfers data between on-chip peripheral modules such as USART, SPI, SSC and on- and off-chip memories. Using the PDCA avoids CPU intervention for data transfers, improving the performance of the microcontroller. The PDCA can transfer data from memory to a peripheral or from a peripheral to memory.

The given example is a transfer of an ASCII animation stored in internal flash to the USART_1 output. The ASCII animation is divived in two files (ascii_anim1.h and ascii_anim2.h).

Compilation Info
