Cyclone is loaded from microcontroller FLASH, the configuration file is inside hex.

Work on the electronic load is slow, it is very difficult to design a user interface for graphical LCD.

LCD type - TIC154A (132 x 64 dots, controller - UC1601S, I2C interface). The photo shows the old version TIC151 (blue), which is now no longer available.

P.S. There is a previous version of the generator using 1602 LCD.

Interesting design, very smart idea to use a digital line driver and adjust it's supply voltage instead of using a very fast variable-gain (one way or another) amplifier.
