Last Updated:02/27/2018

Question:

Where can I find the references to module guide resources for the DMAC HAL Module on r_dmac?

Answer:

Information on the module guide itself and the associated resources and known issues are available here.

Introduction

The Direct Memory Access Controller or DMAC HAL module provides high-level APIs for data-transfer applications and uses the DMAC peripheral on the Synergy MCU. A user-defined callback can be created to inform the CPU when transfer events occur.

The DMAC HAL module moves data from a user-specified source to a user-specified destination when an interrupt or event occurs. The DMAC HAL module supports the following:

  • DMAC module on a Synergy MCU
  • Interrupts, if desired
  • Multiple transfer modes
    • Single Transfer
    • Repeat Transfer
    • Block Transfer
    • Address increment or fixed modes
  • Multiple channels, with the number depending on the MCU used
