    ADS7955 SPI ADC kernel driver limited to 2.5Khz

    Sergio_Ammirata_Ph.D.

      Can anyone comment on why we can only get 2.5Khz measurement retrieval speed from the ADS7955 kernel driver provided with the Edison?

      Is it a limitation of the kernel drivers or the SPI hardware itself? Does anyone know where the bottleneck is?

      This AD device is advertised as having 1Mhz measurement rate but yet when paired with the Edison it seems to be crippled at 2.5Khz.

      Please Help!
