Introduction

This is the documentation for the data structures, functions, variables, defines, enums, and typedefs for the DACIFB driver. It also comes bundled with an application-example of usage.

This example demonstrates how to use the DACIFB driver with the internal timer as sampling rate source. The DACIFB collects data through the PDCA. Once all the data are transmitted to the DACIFB, a PDCA transfer is reloaded. Operating mode: On DAC output [PA15 (microphone output) on UC3C_EK] a sinewave is generated. All the element of the sinewave, stored in an internal buffer, are transmitted to the PDCA through the DACIFB.
