    Pmod wifi

    Hi, I have two problems regarding wifi 1- I am trying to connect the pmod wifi to an arduino uno. I looked for a library, the best I could found is the WiShield https://github.com/airsoftsoldrecn9/WiShield . Clearly, this library is for the WiShield https://www.elechouse.com/elechouse/index.php?main_page=product_info&cPath=90_186&products_id=2165 but I thought because they use the same wifi chip as the pmod wifi this could work. However, after I manage to compile the library (I attached the working library after some minor modification in order to for it to compile) and after I connected the pmod wifi to the SPI of the arduino uno nothing seems to work. I tried to debug and I noticed that the code stuck in initialization stage, specifically in the file g2100.cpp line 144 (do-while loop). Could any one be kind enough to help or, if there is a working library for pmod wifi, that would be great. 2- I have the chipkit wi-fire rev C,I tried the example WifiTcpEchoServer which is working just fine. However, I need to make the kit act as TcpClient, so I tried the example WifiTCPEchoClient, however it does not work. The problem is that the kit does connect to the router, however, it does not connect to another tcp server on the PC. I tested to see if that is a problem with firewall, but it is not. I tired to debug and I noticed that the code stops at deIPcK.tcpConnect function. I appreciate any help. Thanks WiShield3.zip
  2. Hi, I'm an unexperienced Zedboard user. I want to connect to the FMC-LPC connector, and route those signals to another board. How can I do it? Possibly using components that I can solder by hand. I asked the question at the Zedboard support forum and they replied "Please ask your question over at digilent as they are the main contact for educational support." Thank you.
  3. I am using an FT232 breakout board to control a rotary sensor through Python 2.7 If I plug in the AD2 first, my python code fails due to "no device found". If I plug in the FT232 first, and establish the connection with Python, everything works OK. How can I track down the cause and resolve it? The errors listed follow: C:\Python27\lib\site-packages\adafruit_gpio-1.0.3-py2.7.egg\Adafruit_GPIO\FT232H.pyc in __init__(self, vid, pid, serial) 148 if serial is None: 149 # Open USB connection for specified VID and PID if no serial is specified. --> 150 self._check(ftdi.usb_open, vid, pid) 151 else: 152 # Open USB connection for VID, PID, serial.

  4. Hello. I was wondering which possible ways there are to connect 2 Zedboard. I read this thread about using an FMC-to-FMC cable and the OP was recommended to look at this. At the moment, I can't afford buying such cables so I was wondering if there are other ways?? I thought of using I2C to communicate one with another (I'd just need to get a few bits from the other Zedboard) but I'm clueless about which connection/pins I should use. Thanks in advance.
  5. My lab is currently using an ATLYS board to run an experiment on a piece of hardware. We'd like to collect as much data as possible, which may involve having multiple instances of the hardware, each connected to a different ATLYS board. Is it possible to have more than one ATLYS connected via Ethernet to a given PC? If so, what is the maximum practical amount and what are the best practices for accomplishing this? If not, are there any alternatives you can suggest? Thanks!
