Example MicroPython code to interact with an AD5592r chip
# The microcontroller used was a SeeedStudio XIAO RP2040.
# Modify `spi` and `cs` appropriately to work on any other micro.
from machine import Pin, SPI
spi = SPI(0, baudrate=20_000_000) # Initialise SPI at 20MHz. Note that on RP2040 due to clock configurations this is closer to 15MHz.
cs = Pin.board.CSn
cs.init(Pin.OUT, value=1) # Initialise CS high, ie no transmission
