Hello all, I'm using an ads8320 analog/digital converter connected to a 2S3C2440 Samsung ucontroller by a SPI bus, I'm using spidev driver on kernel 2.6.32 to access it from user space and this works fine. The problem occurs because I want to access this adc in your max sample rate possible (100K Samples/s according datasheet, 50% of this for me will be great) saving this data, reading using an application in user space only reach 200 Samples/s in linux kernel, this is for me was not surprising because the application runs in user space and process scheduler time slice prevents achieve a faster sample rate. I want to know the best way to access this adc (I believe I need write a kernel driver), there's some reference example or documentation to do this ? Some audio capture driver can serve as reference ?
