  1. It seems that SD card does nothing, because, without Internet connection, OpenScope USB connection to WaveformsLive works regardless is card inserted or no. P.S. Maybe it works from the browser cache?
  2. So once I've logged a file to an SD card, how do I get hold of the data? I can download the file to my computer but I can't read it as its in some unknown binary format and I can't export it to something like and ascii text or .csv file. Am I missing something here? or have I got a logger that can capture data but the data can't be displayed, viewed or otherwise accessed?
  3. I need to archive data from a serial eeprom to the sd card on the WF32. My problem is that I can't find a sample sketch that uses the WF32 on-board SD card for user data storage and retrieval. There was an Instructable for using the WF32 as a Web Server. The use of the SD card was embedded somewhere. I never could find it. Help will be very much appreciated.
  4. Hello Digilent Community, I am working on a image processing project and was wondering if anyone had advice or could point me in the right direction. I have tried following some tutorials and example projects, but I am still trying to wrap my head around Xilinx Vivado and SDK. The project really shouldn't be very difficult, I think I am just missing some information or the best way to go about doing it. For the project I am using the Zybo z7-20 development board and want to save two images to an SD card. The two pictures are black and white frames from a video just seconds apart, so
  5. Hello, I am trying to develop a simple verilog code on Arty-Z7-10 that writes to the SD card on the PL side, without having to use SDK software. To do so, I believe I need to setup my SD card pins as EMIO in the ZYNQ and modify the constraint file to uses correct pin mapping. However, I wonder if anyone has done such type of coding before and is able to provide me with more detailed information. I found this tutorial which has tried to do same thing with SPI, but it was not very detailed. https://forums.xilinx.com/t5/Xcell-Daily-Blog-Archived/Adam-Taylor-s-MicroZed-Chronicles-Part193
  6. Hello, Does PmodSD (https://reference.digilentinc.com/reference/pmod/pmodsd/reference-manual) support SD mode of operation? Is it designed only to work with SPI mode as written in the reference manual? Please let me know Regards, Vinay Shenoy
  7. Hello all, I have a question pertaining to my ZedBoard. I'm running Linux on the PS using the built in SD card slot. I'm simultaneously building an isolated system in the PL, currently consisting of a Microblaze running a baremetal application. Now I'd like to run Python in the PL without touching the PS setup. Could I use the SD card Pmod to persist Linux to run on the Microblaze? I know I can't touch the existing SPI since it belongs to the PS, and I'd also like plenty of storage. Thank you for your time
  8. I've been looking over the SD library that was installed as part of the chipKIT boards (ver 1.4.1) and I get the distinct impression that it implements the SPI protocol to the SD card using bit-banging, rather than a PIC32 SPI peripheral. Is this correct? Assuming so, are there any Arduino-compatible libraries for the Wi-FIRE that utilized the SPI peripherals? Assuming not, is my best be to go with MPLAB Harmony? (I'm an old MPLAB-X guy using version 2.10 and an old peripheral library)
  9. Hello everyone! Someone knows how read and write files in the SD card from Standalone application in SDSoC? I think that I have to set up the option in the BSP but i am not secure, and i don't know how do this. Thanks for your time, Raúl.
  10. Hello to all, While considering to use SD card socket integrated into the Zybo board I've noticed that its definition (package constraints) was not included into the board files. I guess that I can try to add it by myself or ask Digilent to be kind and add it. Unfortunately, I am not familiar with the software used to generate the XML file. Perhaps it can be done in Vivado? Please, advise me on that. Thank you!
  11. Hi to all, Today I tried to test PmodSd module using Digilent source code posted on Github and failed to compile. The errors are shown on the attached snapshot. It appears that the code is expecting Microblase processor instead of ARM. I failed to find proper fix and am hoping that authors of this driver can offer a solution for the Zynq. Thank you in advance!
  12. Hi all, I am using a Nexys 4 DDR board to interface microSD and microSDHC cards using the SPI mode. (For those interested in what the whole thing is all about, click here.) Might it be, that microSD cards are needing current in the range of 10mA (e.g. look at Transcend's 2GB SD card datasheet - link) and microSDHC (SDHC vs SD) are needing 10x of this, e.g. look here at Samsung's 32GB SDHC card: http://www.singerphoto.co.za/SingerPhotographicOnlineDocuments/WebImages/SellSheetPDFs/mesamp64a.pdf How much current is the Nexys 4 DDR SD Card slot able to supply? The first c
  13. Hello, How can I communicate with the SD card in bare metal application at Zybo board< There are some free FAT32/16 filesystem stacks, but how to make them work with Zybo HW? Is there any reference solution for file read/write?
  14. We've gotten the second SD controller working on Zedboard and Zybo, using PMOD SD connected via either the MIO PMOD E connector or EMIO and one of the other PMOD connectors. We've tested it with SD cards and with an Atheros WiFi card. There are a number of changes to make in order to get it working. 1) Configure MIO to connect the second controller to the MIO pins. Or Configure MIO so that the second controller is connected to none of the MIO pins so that it can be connected via EMIO and programmable logic. We did this in clearreg.c, which is run by our FSBL before it jumps to the entry
  15. Hello I would like to store the data collected by the analog shield on an sd card. I'm using and Arduino UNO and the Keyes Data Logging Shield http://www.tinkbox.ph/sites/tinkbox.ph/files/downloads/Keyes - Data Logging Module (rev 1.0).pdf Both the Analog Shield and the Data Logging Shield works perfectly alone, but as soon as I stack both of them on top of the Arduino the Analog Shield stop providing output on the serial interface. I changed the CS pin on the Keyes Data Logging Shield from 10 to 4 but nothing happened. Suggestions? Bests, Andrea
