Hi，Jean-Pierre，
I plan to run phwhisper on Linux system through jupyter. I can find the phwhisper device through “lsusb”, as follows:
shitou@shitou-virtual-machine:~/Desktop$ lsusb
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 002: ID 2b3e:c610 NewAE Technology Inc. PhyWhisperer-USB
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 003: ID 0e0f:0002 VMware, Inc. Virtual USB Hub
Bus 002 Device 002: ID 0e0f:0003 VMware, Inc. Virtual Mouse
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
The contents of the script file to be called are as follows:
import phywhisperer.usb as pw
phy = pw.Usb()
phy.con()
phy.addpattern = True #Adds captured data back, otherwise we capture 'after'
phy.set_power_source("off")
phy.reset_fpga()
phy.set_pattern([0x40, 0x00])
phy.arm()
phy.set_power_source("5V")
#wait a second for device enumeration, 'capturing' LED goes out
raw = phy.read_capture_data()
# WARNING:root:Capture FIFO overflow. Capture stopped when overflow detected.
packets = phy.split_packets(raw)
printPackets = pw.USBSimplePrintSink(highspeed=phy.get_usb_mode() == 'HS')
for packet in packets:
printPackets.handle_usb_packet(ts=packet['timestamp'], buf=bytearray(packet['contents']), flags=0)
Copy the script to jupyter edit area. After running, the error message is as follows:
