The slide switches on the Arty define what address to read. The state machine from the previous post already reserved a state ...en-USTelligent Community 12https://community.element14.com/technologies/fpga-group/b/blog/posts/arty-talk-to-spi-eeprom---part-2b-eeprom-readTue, 28 Jun 2022 09:37:41 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:5c87012d-a9d5-4df0-833e-c3b9ca171bbbJan Cumps0<p>Success:</p> <p><img src="/resized-image/__size/1280x720/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-5c87012d-a9d5-4df0-833e-c3b9ca171bbb/pastedimage1656408975152v1.png" alt=" " /></p> <p></p> <p>The IC was defect. I tested it with an <a href="https://docs.arduino.cc/tutorials/generic/introduction-to-the-serial-peripheral-interface" rel="noopener noreferrer" target="_blank">Arduino example</a>, and that failed too. Putting in another IC fixed it.<br />At that time, my code started to work too.</p><img src="https://community.element14.com/aggbug?PostID=23866&AppID=19&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/technologies/fpga-group/b/blog/posts/arty-talk-to-spi-eeprom---part-2b-eeprom-readSun, 26 Jun 2022 16:09:48 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:5c87012d-a9d5-4df0-833e-c3b9ca171bbbgenebren1<p>Interesting that the factory state of the memory is not specified.&nbsp; I have seen some devices that are specified and others that are not.&nbsp; Having been in a similar place, it is somewhat disconcerting not knowing if your read is working or not, until you complete the write logic and begin to modify the memory.</p> <p>Great work so far.&nbsp; Keep up the good work!</p><img src="https://community.element14.com/aggbug?PostID=23866&AppID=19&AppType=Weblog&ContentType=0" width="1" height="1">
