The bellow is explained how long it takes to read frame by hardware. We also need to add DMA timeout + PCIe transfer time on top of that before we can expect to acquire frame
Full readout time = exposure time + fot + readout time
FOT = (reg73 + 2*(16/number_outputs))*129*clk_per
Readout time = (129 * clk_per * 16/number_outputs) * num_lines,
where:
reg73= 7 (I think, just check this)
number_outputs = 16 -for 10bit, 4 - for 12bit
clk_per=25ns
num_lines = 1088 or 2047 or 1, depends what you set....
