(OP)
Hello !!
I have interfacing AD7714(sigma delta ADC,SPI Interface) with PIC Micom.
I did the same example circuit and programing in the datasheet, But it is not progressed..
The difference in my circuit with example circuit is that replace Ref Chipset(AD780) with voltage divider resister.
SDO data seems to digital data(low,high), and soon it go to 3-state.
By the way, can SDO data output or not By Ref+?
