/members-area/personalblogs/b/blog/posts/arduino-r-2r-setting-the-signal-amplitudeI&#39;m back again with the resistor DAC on an Arduino Uno as a simple audio generator. I&#39;m not clear how I came to do so many blogs on it, but this is going to be the last one. Here&#39;s the latest sketch with commands for setting the output level as ...en-USTelligent Community 12https://community.element14.com/members-area/personalblogs/b/blog/posts/arduino-r-2r-setting-the-signal-amplitudeMon, 30 Apr 2018 16:02:27 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:ef2c9037-8b4c-4519-a72d-998708606802shabaz2<p>Hi Jon,</p><p>&nbsp;</p><p>It is very neat you got all that to function on an Uno, including amplitude adjustments and parsing the interace in real-time. It is fairly complete already! Nice feature/performance mix.</p><p>&nbsp;</p><p>I too have been working on a frequency generator (a work in progress for an awfully long time), but the coding was easier since I used an external IC to do the actual signal generation, and I still found it hard to get the parsing all sorted (I&#39;m not using SCPI, but the concept was similar).</p><img src="https://community.element14.com/aggbug?PostID=4734&AppID=293&AppType=Weblog&ContentType=0" width="1" height="1">
