    Reading QSPI ADS7818 ADC

    ben.satkiewicz

      I purchased some QSPI ADCs that I am attempting to use with the PSOC SPI object,

         

      http://www.mouser.com/ds/2/405/sbas078-98888.pdf

         

      The SPIM_ReadRXData() does not work for some reason. It appears the reason why is the SPI object is not activating upon ReadRXData. According to the datasheet, the ReadRXData only reads the buffer, and does not generate activity on the bus. My scope is not detecting any.

         

      Should ReadRXData generate bus activity? If not, how do you read from read only SPI devices like the ADS7818 with the SPI object?
