Detailed Description

This frontend handles the real-time data acquisition for MUPIX devices, using direct memory access (DMA) to collect data blocks and transfer them to MIDAS events. It sets up necessary buffers, device interfaces, and ODB configuration to support robust data streaming.

Key functionalities: * Initializes and maps a DMA buffer for high-throughput data acquisition. * Manages device communication through mudaq::DmaMudaqDevice. * Handles multiple event streams via software buffering (mevents). * Provides run-time configuration through MIDAS Online Database (ODB). * Supports both real hardware and dummy simulation via preprocessor flags.

This file complements quads_config_fe.cpp by performing the actual data acquisition, while quads_config_fe.cpp handles initialization and configuration.

Note:

Define NO_A10_BOARD to build without hardware-specific mappings.
