Constructor Details

WriteFPGARegister

public WriteFPGARegister(FPGA fpga,
 MemoryLocation register,
 int value,
 BMPBoard board)

Parameters:

fpga - FPGA (0, 1 or 2 on SpiNN-5 board) to communicate with.

register - Register address to read to. Must be aligned.

value - A 32-bit value to write to the register.

board - which board to write the ADC register on

Throws:

IllegalArgumentException - If FPGA.FPGA_ALL is used or the register address is not aligned.
