Phil: document what this thing does, including how bitfiles work and how they’re generated/where they’re located.

read_data(length: int, addr: int = 160, blockSize: int = 16) → bytearray

Read a buffer’s worth of data

Parameters:

• length (int) – Amount of data to read

• addr (int) – FPGA address to read from

• blockSize (int) – Size of individual blocks (in what unit?)

Returns:

bytearray

set_wire(addr: int, val: int) → None

Phil! what does this do?

Parameters:

• addr –

  ?

• val –

  ?

upload_bit(bit_file: str) → None

Upload a configuration bitfile to the FPGA

Parameters:

bit_file (str) – Path to the bitfile
