I am trying to interface PMOD DA4 with atlys FPGA but nothing is coming at output. help me to rectify what wrong with code. module spi_master_v1( input sys_clk, input rst, output reg cs, output reg MOSI, output reg sclk, // input [31:0] in_data, output reg done ); // Internal registers reg [10:0] count; reg [31:0] temp_data; reg [5:0] bit_count; reg [11:0] count2; // state declearation reg [1:0] state; parameter idle = 2'b00; parameter data_tx = 2'b01;
Hello, I am Raghu, doing my Master Thesis. I am using Zedboard to emulate few sensor's signals. I have already implemented DA1 and AD2 on to Zedboard and connected in the loop. They both work perfectly fine. But next step was to implement DA4 in my design, and I didn't find any drivers for the same. So I tried using normal AXI SPI IP in the hardware design for DA4 and tried to develop my own driver (considering DA1's driver as an example). All the initialization part works perfectly fine and the communication also takes place as per DA4's datasheet. But when it is asked to send data, it i
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
Hello, I am trying to use the pmod DA4 with my Arty S750 board. I'm aware that Digilent does not offer an IP for interacting with the Pmod, so I took it upon myself to design one. Anyways, things seemed to be going well until I actually tested the DA4. I know that the DA4 uses SPI to communicate, so I programmed the IP to communicate that way, and it does (outputs from the pmod connector correctly seen on an oscilloscope), but every time I connect it to the DAC I can't get much of anything to come out of the channels. I've read through the AD5628 reference manual, but a few thin
