• How to use capture mode (WDTH_CAP) on BF512?

    Hi,

    I'm tring to use the capture mode of the BF512 in order to find the frequency of an incoming PWM signal.

    The PWM signal is connected to TIMER3 and the timer is set to WDTH_CAP mode and also to PULSE_HI and PERIOD_CNT=1.

    If i understand correctly…

    Hi Guys,

    In BF512, when PPI works in RX mode, 2  external frame syncs mode, in hardware manual, it says

    we should provide an external pull-down to GND for the PPI_FS3 pin.

    However the PPI_FS pin is multiplexing with SPI0 boot CS signal, if we choose…
