Плата DDS генератора AD9833

A review of a DDS signal generator board based on the AD9833 chip, capable of generating sine, sawtooth, and square wave signals up to 12.5 MHz via SPI control. The author used an STM8 microcontroller running eForth for interactive SPI command sending instead of traditional firmware flashing, and provided oscilloscope measurements showing signal quality degradation at higher frequencies.
