In the context of the master’s thesis, a system was designed which is monitored by a control unit (FPGA or microcontroller) via the SPI protocol. The system has a modular design that enables the construction of an arbitrary complex assembly using control modules. One control module offers 4 channels of digital-to-analog converter, 7 channels of analog-to-digital converter and 7 digital inputs or outputs. With the designed system, 96 such modules can be controlled using the Matlab software package which enables very high flexibility in the construction of laser systems. All the control modules which are added to the system communicate over one SPI bus, so when adding a new control module to the system it is not necessary to change the hardware, because we only connect it to the SPI bus and apply changes to the graphical interface.
