@guymcswain I use RPI to do this because it need no other devices and I saw that the clocks can achieve 100MHz or higher for RPI peripheral. So I want...

@guymcswain Thanks for your patience. I need to monitor the signal continuously without time gap between two data acquest. I tried `spiOpen`, `spiXfer` (I didn't found `spiTransfer` API), `spiClose`. But...

@guymcswain If I want to streaming the input data without any gaps, can I use `spiXfer` to achieve this?
