Detailed Description

The RECEIVER_DATA structure contains data from one receiver.

impulse_response[] is a subset of the 4064 sample array inside the DW1000 chip. We only send back 64 samples, starting at first_sample_number.

FPI is a 10.6 fixed point value. It is a non-integer index into the impulse response date which tells us where the first pulse appears.

Due to the large size of the data packet, only one receiver's data is sent in each EtherCAT packet. When a message arrives at the base station, data is collected from each in turn, and sent to the host in individual EtherCAT packets. Therefore it takes 4 EtherCAT packets to transmit all of the receiver data. The 4 packets will all have the same sequence_number, but a different receiver_number.

command_type: currently undecided function sequence_number: When this changes, it signals the arrival of a new message receiver_number: Which of the 4 receivers is this data from? receiver_data: Data from one receiver
