  1. I recommend a custom case to house the board, I have a dozen radio shack generic project cases I purchased years ago before RS went out of business. Pmod cables can be purchased from Digilen to create custom expansion ports from within the case and other suppliers also have parts such as Power supply connectors that if you drill a hole in the case you can easily add a Plug in PS connection. Note I am not saying that you did actually fry the board yourself but determine if possible the nature of the Fault. And I would also recommend reading the Digilent Warranty terms ASAP, as i
  2. I am not certain if you have any return or repair rights from digilent if so I would suggest you take that option if possible and necessary. But in either case the first thing I would do is try to determine the root cause. power on then sudden power off and it wont come back on failure means it was working then now its not getting power. Since the power supply is the USB port I would check the port by trying to use it for a different device such as a FLASH USB drive and see if that functions in the port you were using for the arty board. if the port tests out as good then next try
  3. thanks so much for the info, I am about to continue working on this project and before I do the first step physical connection I need to verify RPI gpio pin to arty pmod pin compatibility. I did a lot of bread boarding in my early career life as a technician and in tech school back in the late 80s. But this is my first off boarding project with an FPGA could you direct me please to resources on these matters? Sincerely, DC

    Array

    yes actually that is another concern I am currently using the USB port serial driver 128Kbits limit so 16Kbytes a second is kinda slow once you factor in handshaking two way data and commands its even slower. using the Ethernet which I haven't learned yet might be an advantage, are there any resources on that?
  5. 10 years ago in engineering school I was new to FPGAs also they didn't have ARM cores then and I knew very little about FPGAs. What I know now versus then Ill tell you to carefully consider all of the features of the entire Xilinx FPGA product line before you make your final selection. I had a great starter learning experience with the Digilent Xilinx Spartan 3 board but wish I would have considered the Digilent Spartan 6 board back then because it had a lot more room to grow. Regards, DC

    Array

    I have found online lots or resources for creating arrays of signals, but what I have is the need to create an array of processes. for example I have a simple process that adds 2 8bit signals: sigT <= sig1 + sig2; I would like to create an Array of a particular circuit design where I could use dozens, perhaps 100s and if I am able to upgrade to your Artix200 or kintex products soon perhaps 1000s. can you direct me to such resources that might lead me to complete this kind of task please? Sincerely, DC
  7. also have you considered an asynchronous or synchronous divide by? DC
  8. instead of tying a port to a port try tying input ports to signals then either tie the output port to the signal or selecting the signal to the output port hope this helps, DC
  9. I looked at the path directory you suggested and yes it was there. Thanks, seems strange that it didn't pick it up there by default as it usually does. Thanks again DC
  10. I have written many vhdl modules using vivado and every time I run my previous designs and generate a bit stream I immedietly hit program device and the bitstream is listed and I just click on that and the file streams to my board and its programmed. Recently ive created a new design using features that are new to me. every time I try to generate a bitstream with this new design it says write bit stream completed like it always does, but when I go to program the device with this design the bit stream is not listed and I cannot find it in any of the folders im working with. I even tried to t
  11. I cant seem to find the C64 information on boot address when a cartridge is inserted, would you happen to know it?
  12. Thanks, Lots of Great Ideas and places to turn or look next! Awesome!
  13. I decided to upload my core file that I wrote which is 99% of the program in case you or others want to take a look. I know I just said I wouldn't publish the project, but I figured the internet is full of comparable code already and besides there are bugs ( I was slowly eliminating as I went ). I think the bug was gathered erroneously from data specs I took from manuals, which I either interpreted incorrectly or it was represented in the specs inaccurately. I had previously put in 2 debugging modes to send output reports to files, thou this method moved ahead very slowly and was like looki
  14. P.S. you can also think of it as you learning from me (where applicable)!
  15. First, Thanks For the speedy reply! all this talking C64 made me dust off the C64 emulator I was working upon. Reading the Date Modified saying 2/28/2011! I guess it was really dusty. Basically what I had achieved was that it loaded the ROMS and an OP code table (addressing modes and such) and started to execute the ROM Basic Program thru the Kernel. I segmented the Kernels execution so it bypassed all sound and graphics processing and only did Text IN OUT to a scrollable text box (see attached jpeg below). It does manage to do text responses like the syntax error message comes compl
