how to do fast sampling in Linux?
I've been working on the AD7476 driver for several weeks.
It supports many ADCs. For the test system I need sampling around 1 MHz.
Write everything in Python. I made a driver for PyADI. Added support for hrtimer.
And when I measured Sampling on SPI, I was very disappointed. the maximum Sampling is only 25uS, which is 40K.
Is it possible to increase sampling without using FPGA?
