Added third thread to FTDI code to handle file writing, resulting in small improvement to performance.
Added ability to set test mode and integration time to FTDI code.
- Integration time set in units of 5us above minimum of 170us to maximum of 1455us (i.e. 170us + 255*5us).
CTRL-C commands are caught by FTDI code to exit cleanly from DAQ, closing connection with FPGA properly.
LibFTDI can be installed on Raspberry Pi and can receive data from Nexys Video.
- Latest version of FTDI code does not work on Pi, likely some compiler issues with "fancier" functions.
- Will rebuild latest version from older version of code that does work on Pi to find problem functions.
Tested daisy-chain with resistors in place of photodiodes.
- See the same mirroring whether resistors are in series or in parallel to photodiode.
- Will reach out to Clive and Izzat to continue discussion.
