Hello! I was writing a program to communicate to an AD5722/AD5732/AD5752 DAC ( GitHub link ), and it works through 24-bit SPI communication to send over an 8 bit header and 16 bits of data. While everything does work virtually as intended, with the DAC producing the output voltages I want, I've notic…

Which Arduino board ?

Confirmed for an Arduino Uno. Only in the data signal MOSI and only at the rising edge of the clock.
