Hi Kevin, Thank You for your response. I have attached schematic for your reference. I was trying to generate triangular waveform by writing values from 0 to 4095 to DAC register. But at some points, the voltage is suddenly dropping to zero. I have checked the triangular waveform with respect to chip select signal and RW signal. But I could not get any inference because that dip in voltage is very random. I have attached scope images for the reference. Below is the schematic below is the scope of triangular waveform Below is the zoomed scope Below is the code for DAC Thank You
