Re: [time-nuts] Logging SPAD pulses on synced devices (was: Linux PPS clues?)

Hi, Do a SPI bus do this job correctly? I'd have the clock on one line and the pulses logged on a second line. Like CLK for clock pulses and MOSI/MISO for serial logging of pulses. I'd avoid I2C because of addressing packets. Best Regards, Ilia On 11/05/16 04:48, Casey L. Jones wrote: Yes,

Hi, and thank you for these suggestions. Currently this project becomes reality (slowly): this kind of synchronization/grabbing is very interesting, but I need something fast (I expect the SPAD with active quenching circuitry could output 30ns pulses, and the quantization frequency I hope to
