Frame Rate on X4M03

    Hi,

    while playing around wit the X4M03 I stumbled across the following:

    setting pps=400, iterations=16, trx_clocks_per_pulse=4 gives a frame duration of 27ms according to equation 7.6 in the manual (default values on all other registers). This would theoretically allow for a frame rate of 37FPS. But the maximum FPS I can achieve before the module hangs is only 4FPS.

    What could be the reason for this? The problem is probably not the data transfer overhead because this FPS limit holds for both raw and downconverted data, while the data amount of downconverted data is only 1/4 of the raw data. Thanks for your time.

    Cheers
    Georg

    Thanks Aksel, Sorry, it was my fault. I could not delete the original post. The reason was that I forgot to set the DAC_min/max. The defaults are a very large range. The X4 is an amazing device and I look forward to do nifty things with it.
