AmungoFx3Dumper

Stream dumper for Amungo's NTLab's nt1065 board

Usage:

AmungoFx3Dumper FX3_IMAGE NT1065_CFG OUT_FILE|stdout SECONDS|inf DRV_TYPE

FX3_IMAGE - name of img file with firmware for cypress FX3 chip

NT1065_CFG - name of hex file with nt1065 configuration

OUT_FILE - output file name, use 'stdout' as a file name to direct signal to standart output stream

SECONDS - number of seconds to dump, use 'inf' to dump until Ctrl-C is pressed

DRV_TYPE - driver installed in your system. Use 'cypress' or 'libusb'

Examples:

• dumping one minute of signal and use cypress driver:
• AmungoFx3Dumper AmungoItsFx3Firmware.img nt1065.hex dump4ch.bin 60 cypress
• dumping signal non-stop to stdout:
• AmungoFx3Dumper AmungoItsFx3Firmware.img nt1065.hex stdout inf libusb

File format

The program dumps all data from a FX3 board without any changes. Usually the format is:

• 4 channels
• 2 bits per sample per channel
• Overall 8 bits (1 byte) per one sample for all channels
• Decode table is
• 00b -> 1
• 01b -> 3
• 10b -> -1
• 11b -> -3

You can use AmgExtract to extract several channels from output file and converting data to usual signed char format. AmgExtract is located here: https://github.com/amungo/AmgExtract
