Via a Win10 PC, the TXT-Controller and an old CPLD board I made a new version to control my microscope. I use a very old version MAXII CPLD board. The TXT is connected via the I2C. The housing is a 3D print version. The software for the CPLD is a smaller version of my larger Fischertechnik BOX. The CPLD has only 2000 LE compared to the 22,000 of the FPGA. Still, this was more than enough, I only need 850 LE to support all the microscope functions. Everything now runs under Win10 on a new powerful hardware.

The microscope is equipped with a stepper motor and 5 COB power LEDs each 125W. Exposure, number of photos to be taken, step size, camera control etc. is done via the Robopro gprogram that I made earlier. 2 large UHD 32 inch screens give a good overview of the necessary programs.
