Hey guys i am making a digital weighing scale CS5460 it uses the IC CS5460 as the main processing unit. CS5460 has SPI interfacing. The circuit is already present but the microcontroller used is 89C52 or nouvoton. I want it to be interfaced with arduino and transfer the data to PC using serial communication.
I tried interfacing it using SPI communication but it is not returning any data. It seems that it is not working at all.
Guys please help me out to interface with arduino. The circuit diagram and the datasheet is attached .
