4 Packet Format

Packets are retrieved by ndigo6g12_read(). They are of type crono_packet.

• Each hit on an ADC channel is stored in one packet. The format of the payload data (see crono_packet::data) is explained in Section 4.4.

• All TDC hits within the time given by ndigo6g12_param_info::tdc_rollover_period are stored in a single packet (stored in the payload data). The memory layout thereof is shown in Section 4.5.

Note

The minimum packet length depends on the application type. See Section 2.1 for details.
