I'm trying to use a library of AD7734 by analog to get a data of a voltage measure between -10V and +10V. For this application i am using a AIN0 port , and the Channel1. I created the SPI function ( SPI_READ, SPI_INIT and SPI_SEND) using the information on Datasheet of microcontroller. In the main program of my code , i tried put the initialization of spi ( SPI_INIT), Set_registervalue_AD7734(...) and after Getregsitervalue_AD7734(...) but doesn't work at all. To test and debug i am using a logic analyzer and a oscilloscope. Data ConvertersPrecision ADCs@
