    SPI communication between PSOC5 and ADC AD7195

    fournier_1591946

      hello dear CYPRESS community,

         

       

         

      I need to communicate (SPI) between PSOC5 (Master)  and the ADC AD7195.

         

      I have to configure  the ADC and take measurements.

         

      Is there someone who can help me and verify my code? 

         

      I search code example for this type of ADC.

         

      ADC Sync pin not connected, MISO connect to Dout/ready, MOSI connect to DIN, sclk connect to sclk, ss not connected.

         

      CS connect to P1_5  port of PSOC5 ( ADC_CS)

         

      PSOC5: 5V  & VDDIO=DVDD ;   ADC : 5V USB    AGND = PSCOC5 GND   

         

      my 'C' code:

         

      when I ask for ADC ID , I receive x00 instead of xA6

         

      when I ask for ADC Status Register, I receive x00 instead of x80.

         

      when I ask for ADC configuration Register, I receive x0000A6 instead of x000117. 

         

      when I ask for ADC mode Register, I receive x000000 instead of x080060. 

         

       

         

      Best Regards
