Hello, I would recommend checking out the troubleshooting steps listed in the initial post on this thread. If none of those work, please post back here so that we can direct you further. Thanks, JColvin

A customer asked the following question on our website: We have an "Electronics Explorer" that will not power up. Do you provide out of warranty bench repair and or replacement? Please advise.Thank You. The response is below.

When i was working with my Analog Discovery yesterday, it suddenly stopped working. The problems are as follows;1. I cannot connect my analog to waveforms - it tells me that "Device configuration failed" and gives me the error message:DptilO failed ERC:7Device configuration failed (PLL 3).2. When i somehow sometimes manage to get through the configuration phase, Waveforms simply tells me that "The Analog Discovery has stopped working due to an overcurrent condition" - even though i haven't connected it to anything at all. 3. All the time i am let through to the Digilent Waveforms menu, there is a flashing message in the bottom right corner saying "Discovery OFF".I do of course have screenshots of all three issues, but it seems like i cannot attach them here. For troubleshooting i have tried using different USB ports on my PC - and even tried connecting the Analog Discovery to different Computers, where other Analog Discoveries were working, but nothing seemed to be able to solve the problem - my Analog Discovery gave the same error messages everywhere. I also tried the provided troubleshooting steps and restart the analog etc. I hope that you can help me! I'm not familiar with this error, so I don't personally have any recommendations, but I'll make sure the appropriate engineer see's your question. You can post any screenshots that you have though on our Forum Gallery (you'll need to create an album). Thanks, JColvin

A customer on our website asked the following question: Hi, I did all the troubleshooting techniques in the thread and I am still getting the error "Device configuration failed". I am attaching the error message with this email. Is there anything further the customer could try? The error message they refer to is available on our Gallery here. Thanks, JColvin

Hi Ton, If you can post your question in chipKIT section of the Forum, we can make sure the appropriate applications engineer can see your question and help you. Thanks, JColvin

Hi SteveD, I sincerely apologize that this thread has gotten dropped by our team, I'll make sure that Tommy gets back to you on this. As for the PmodOLEDrgb, I found the datasheet for the SSD1331 available from Adafruit here. However, like the PmodOLED this datasheet is rather difficult to decipher, so I would personally look at the Cpp and header file for the PmodOLEDrgb (available to download from it's Resource Center here in the MPIDE zip file). I agree that this is not the most helpful in terms of developing a MicroBlaze project, but at the very least will give you some insight into the initialization procedure and the needed SPI commands to send the display controller. Thank you for your patience, JColvin

Hi Steve, I know I would certainly like some cool FPGA projects for various Pmods; I know there are plans to do this in the near future. In the meantime, I'll ask some of our applications engineers to see if they have helpful resources that they know of. Thanks, JColvin

Hi Dan, I looked into this since I also recall having issues with the backslash character, and found that (bizzare as it seems) the backslash does not have a predefined character for it. The reason for this is because the PmodCLS uses the set of characters that is directly inside the memory of the KS0066 LCD controller that the host board (in your case a Basys 3) communicates with. The set of characters that it directly supports are here. (I'll update the PmodCLS reference manual to include this diagram as well) Why Samsung didn't include support in their LCD controller for a backslash is beyond me. I am not aware of a way to directly reconfigure the pre-defined library, so what would be done in this case tell the controller to define a custom character within it's own memory. I can try to explain it if you want since the functionality is provided in the C++ library for MPIDE within the last three functions or so, but I'm not too familiar with FPGA's and their hardware language, so I won't be able to personally help as much there. Let me know if you have any more questions. Thanks, JColvin

Hi shahabamo, I have asked some of our applications engineers about this who will get back to you here on the forum. Thanks, JColvin

Hi Timoleon, That sounds like an interesting project. I'm not sure that Digilent specializes in the solution you're looking for, but perhaps we can help. Could you tell me a little bit more about what you're hoping to do? Thanks, JColvin
