How to Generate a High-Precision Waveform Using a DAC and a Custom PCB

In this article, we’ll develop firmware that will serve as the basis for high-precision, high-speed signal generation. I recently designed an arbitrary waveform generator (AWG) PCB that is built around a C8051F360microcontroller and a TxDAC from Analog Devices. These two ICs communicate via a parallel interface that allows me to generate higher-frequency analog signals by seeking …
