I'm trying to take accurate readings using the "Logger" module in Waveforms 2015. When I power up a simple DC circuit with +5V, and use a DMM I get readings of ~4.44 volts. However when I run the data logger module, all of the readings are <100 mV. Shouldn't the logger be reading ~4.44 volts, or is there some configuration I am missing Thanks in advance!
Hello, I am new to this forum, so I may introduce myself first. I am from Germany and currentlly visiting a technical college here. Next year I will go to a University to study electronic engineering. My biggest hobby is to waste some time with electronics. I really like microcontroller and spend already some time programming them. Now I want to continue with FPGAs. I want to be able to handle some faster data transmissions compared to microcontrollers. My questions now are about the Pmod connectors. How fast data transmissions can I get? In the document which is aviable at the Zybo page there is written that a regular pin can handle 24MHz. How about the high-speed Pmods? Will it be able to achive a maximum of about 200MHz? Is it possible to short the 200Ohm resistors of the normal Pmods to use them as high-speed Pmods or is the PCB layout not suitable? Greetings, MrMcChicken
Hello! I have created some VHDL code (attached) to test if DA4 convertor works. The simulation reveals no problems with timing of SCLK, DATA and SYNC channels according to the AD5628 data sheet, however output of the eight out data pins of DA4 does not work. Basically I am trying to send the the data to JB PMOD. Command and address are tuned by the eight switches on the Nexys4. The used command is 0011 and the address is 1111 (is that correct, by the way?), but I have tried plenty of other commands. Still the problem persists — no out data from DA4. Please do not hesitate asking for additional information. Thank you for your help. pmod.vhd.txt
