  1. Hi, I want to read analog data from ad1 pmod. For Vivado part, I use digilent pmod ips to connet fpga. For SDK part, I use AD1.h and AD1.c library in examples. My sensor sends to me analog values between 0-3.3V. (This is a heart rate ECG values). During using arduino, all heart beat data can be read. But I use same function for zedboard, Analog values doesnt look like arduino's. How I can configure and fix this problem? As you see ad1-zedboard connection as below.
  2. Hey all, First off, I apologize - I'm at work, now, with no access to the hardware, o-scope, etc. So all from memory for now, until I can get some time at home.... NOTE: All development being done under Xilinx ISE 14.7 WebPack. Target platform is an Opal Kelly XEM3005 (Xilinx Spartan 3E) Day 1: Wrote & sim'd Verilog to drive a PMODAD1 12b ADC. Seemed to work as planned. Day 2: Tried interfacing to an Opal Kelly XEM3005 (Spartan 3E) board with 3.3V logic & power. No joy. Funky stuff going on. Began troubleshooting. Day 3: Wrote code for Ras
  3. Hello, I have recently purchased Zedboard along with Pmods AD1 and DA4. I want to implement Gradient Descent algorithm in the Zedboard using these Pmods with bandwidth more than 100 kHz. To get started, I tried to regenerate a analog signal using the Pmods AD1 and DA4. The experiment is completely explained with block design and output plots in the ADC_DAC_1_compressed.pdf. The SDK C code for acquistion and generation (adc_dac.c) as well as for finding max. working speed of DAC (dac_maxv.c) are atttached. The ADC clk is set to 20 MHz and DAC clk is to 50 MHz. It could be observed fro
  4. Hello, I have an Analog Discovery (legacy) and the latest Waveforms app. I am trying to write a script that makes the protocol module write to a 24C16 eeprom, read it back, and print to the screen or window. I can access th I2C (can see on my scope), but I can't print anything. The print() function does nothing unless in debug mode, but then the app seems to hang. I tried Custom mode and Sensor mode. And I tried the ADXL345 example, with a known good breakout board, and it always returns the same thing, doesn't change with orientation of the chip (but my main concern is the eepr
  5. Waveforms 2015 fails with a segmentation fault whenever I connect an Analog Discovery 1 or an Analog Discovery 2. This happens regardless of whether I connect the AD1/AD2 before starting Waveforms 2015 or while Waveforms 2015 is running. Waveforms 2015 appears to work when no AD1 / AD2 is connected I'm running Ubuntu 16.04.1 on x86-64. I installed: digilent.adept.runtime_2.16.5-amd64.deb digilent.waveforms_3.3.7_amd64.deb "lsusb" output for the AD2: Bus 001 Device 008: ID 0403:6014 Future Technology Devices International, Ltd FT232H Single HS USB-UART/FIFO IC "unam
  6. Hello! I recently purchased the Pmod AD1 for the Zynq Z7-10 and I am trying to sample at 44.1 kHz. How can I set up a clock in the PL for this? Every time I set up a PL fabric clock to a multiple of 44.1 kHz, it is off by maybe ~500 Hz or more. Thank you in advance.
  7. Hello I am new to FPGAs, and I'm using Pmods AD1 and DA2 in a control application on ZedBoard, using VIVADO and SDK. Is there any tutorial or hint to know how to start the design and interfacing between ZedBoard and these pmods. Thanks. Elie.
  8. Hi to all, I was successful in creating working project on Zybo board acquiring voltage using Pmod AD1. It is relatively simple. However the goal is to utilize both channels of the AD1 Pmod. For this I am looking for guidance from experts and community. I might be wrong but it seems that I need to create the second instance of Pmod in Vivado but how do I address the second channel pin D1 and how to initialize the second device. Thank you in advance for any clue I forget to mention that Pmod AD1 definitions were copied from the Digilent vivado-library-master. Updat
  9. I recently went to use my Analog Discovery 1 and I found that it was giving me all sorts of strange results that I did not expect. I figured that the calibration must have drifted since I hadn't used the device in a year or so, but when I performed a calibration it was still significantly off. Here's a link to an album showing comparisons between the AD1's readings versus a multimeter: https://drive.google.com/open?id=0B2q6FpLmYUaVb1dQSFpIQVJYWXc . I don't really know what to do at this point, but perhaps someone here has run into this issue before and can recommend a fix. Thanks! Edit: F
  10. Waveforms 2015 on Ubuntu 16.04.1 intermittently fails when selecting an AD1/AD2 device in Waveforms's Device Manager screen, reporting either or both of the following error messages. Subsequent attempts intermittently fail or intermittently succeed. --- Device opening failed --- JtscInitScanChain failed ERC: 0x3E9 Device programming failed. --- --- Device opening failed --- DptiIO failed ERC: 0x7 Device configuration failed (PLL 3). --- System configuration: digilent.adept.runtime_2.16.5-amd64.deb digilent.waveforms_3.4.7_amd64.deb Analog Di
  11. Hi, I recently purchased a nexys 4 board and a Pmod AD1 to get short latency audio input to the fpga. Is there any vhdl example available to get audio samples from the AD1? the Digilent ressource center does not have any ... thanks, Pierre
  12. Looks like the input diode D2 will clamp to cutin voltage of diode if input goes negative and the circuit will survive?
