urukul

  • dds.init() and urukul.init() must be called at least once before the channels can be used. After reboot the hardware, typically the init functions do not need to be called again. However, in case of some kasli errors (e.g. set a instance attribute that is TStr type in the kernel), the init functions need to be called to reset the boards.

TTL

  • TTL input can save approximately ~64 events without overflow. To read more events, you can use edge counter if photon timestamping is not needed, or continuously readout the buffer to a np.array during the timestamping period if timestamping is needed.
