How can we do to read more analog channels on the Avnet Minized ? There is a solution using an external multiplexer and that is what I am going ...en-USTelligent Community 12https://community.element14.com/challenges-projects/design-challenges/pathprogrammable3/b/blog/posts/p2p3-amd-zynq-7000-soc-xadc-external-multiplexer-modeSat, 05 Aug 2023 21:50:55 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:9167965a-1cf5-4b0e-a15b-229fd1abb748javagoza0<p>First version assembled and working!</p> <p><img alt="minized multiplexer" src="/resized-image/__size/1280x720/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-9167965a-1cf5-4b0e-a15b-229fd1abb748/minized_5F00_multiplexer.JPG" /></p><img src="https://community.element14.com/aggbug?PostID=26172&AppID=395&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/challenges-projects/design-challenges/pathprogrammable3/b/blog/posts/p2p3-amd-zynq-7000-soc-xadc-external-multiplexer-modeWed, 19 Jul 2023 08:56:30 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:9167965a-1cf5-4b0e-a15b-229fd1abb748javagoza0<p><img alt=" " src="/resized-image/__size/1280x720/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-9167965a-1cf5-4b0e-a15b-229fd1abb748/multiplexer_5F00_5F00_5F00_pcbs.png" /></p> <p>PCBs have finally come home.<br />It has been my first order to JLCPCB with a special offer<br />Merchandise Total: &euro;0.92<br />Shipping Charge: &euro;0.46<br />Customs duties &amp; taxes: &euro;0.29<br />Total Order: &euro;1.67 ~ 1.87$ USD<br />Received in two weeks.</p><img src="https://community.element14.com/aggbug?PostID=26172&AppID=395&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/challenges-projects/design-challenges/pathprogrammable3/b/blog/posts/p2p3-amd-zynq-7000-soc-xadc-external-multiplexer-modeSun, 02 Jul 2023 09:09:36 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:9167965a-1cf5-4b0e-a15b-229fd1abb748michaelkellett1<p>Useful reference blog for adding some hardware to an AMD series 7 FPGA.</p> <p>Thanks.</p> <p>Will you have time to attempt any measurements of the performance of the multiplexed ADC - linearity is quite hard to measure but can be an issue with single rail multiplexors.</p> <p>(The gain goes very wrong close to ground or power so that if you drive it with DC from a pot you can&#39;t ever get a reading of less than a few lsbs.)</p> <p>MK</p><img src="https://community.element14.com/aggbug?PostID=26172&AppID=395&AppType=Weblog&ContentType=0" width="1" height="1">
