Detailed Description

Spi Driver

Author: Manuel Alejandro Ascencio Ysordia

The SPI module provides services to initiate transmissions with a terminal buffer and call callback functions to notify events. Additionally, you have the option of having an external buffer to have more memory capacity. This module has the possibility of several JOBs, Channels and sequences.
