The purpose of the thesis was to create an inexpensive and independent device to monitor and control the laser projector that can be connected to the LAN network with the possibility of remote access.
Laser scanner controller is based on the latest version of Raspberry Pi 3 Model B+, for which we designed a prototype expansion board, which is connected directly to the Raspberry Pi via general purpose input - output pins.
We used in the implemented circuit two separate DA converters connected via the serial SPI interface.
Printed circuit board was designed with software package Altium Designer the operation of the controller is presented with logic analyzer in graphical form.
