/products/raspberry-pi/raspberrypi_projects/b/blog/posts/offload-raspberry-pi-tasks-with-the-i2c-bus---turning-stepper-motorsThe Raspberry Pi 3 has ability to rapid fire pulses out of its GPIO. It&#39;s surprising how fast! In other words, it can handle a lot of tasks. If the only thing the Pi is expected to do is spin a stepper or servo motor really fast, this is go...en-USTelligent Community 12https://community.element14.com/products/raspberry-pi/raspberrypi_projects/b/blog/posts/offload-raspberry-pi-tasks-with-the-i2c-bus---turning-stepper-motorsWed, 26 Jul 2017 17:18:44 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:4862d368-07b4-45c7-a543-222ff7adbacclealon0<p>Shouldn&#39;t there be a logic ground between the two Arduinos?</p><img src="https://community.element14.com/aggbug?PostID=3265&AppID=84&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/products/raspberry-pi/raspberrypi_projects/b/blog/posts/offload-raspberry-pi-tasks-with-the-i2c-bus---turning-stepper-motorsWed, 05 Jul 2017 16:25:43 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:4862d368-07b4-45c7-a543-222ff7adbaccWorkshopshed0<p>Yet another way of achieving the same results, an FPGA hat.</p><p>&nbsp;</p><p><a class="jive-link-external-small" href="https://blackmesalabs.wordpress.com/2017/07/04/icezero-fpga-hat-for-raspberrypi-servo-example/" rel="nofollow ugc noopener" target="_blank" title="https://blackmesalabs.wordpress.com/2017/07/04/icezero-fpga-hat-for-raspberrypi-servo-example/">https://blackmesalabs.wordpress.com/2017/07/04/icezero-fpga-hat-for-raspberrypi-servo-example/</a> </p><img src="https://community.element14.com/aggbug?PostID=3265&AppID=84&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/products/raspberry-pi/raspberrypi_projects/b/blog/posts/offload-raspberry-pi-tasks-with-the-i2c-bus---turning-stepper-motorsTue, 04 Jul 2017 18:06:19 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:4862d368-07b4-45c7-a543-222ff7adbaccDAB0<p>Hi Cabe,</p><p>&nbsp;</p><p>You could do a simpler implementation using one or two Cypress Semiconductor PSOC boards with the RPi.</p><p>&nbsp;</p><p>The PSOC can handle the voltage conversion levels easily and already have programmable digital cores to handle the stepper motors and just about any other digital and analog interface.</p><p>&nbsp;</p><p>Just a thought.</p><p>&nbsp;</p><p>DAB</p><img src="https://community.element14.com/aggbug?PostID=3265&AppID=84&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/products/raspberry-pi/raspberrypi_projects/b/blog/posts/offload-raspberry-pi-tasks-with-the-i2c-bus---turning-stepper-motorsTue, 04 Jul 2017 15:20:48 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:4862d368-07b4-45c7-a543-222ff7adbaccWorkshopshed1<p>Some of the commercial boards for servos and steppers work like this too</p><img src="https://community.element14.com/aggbug?PostID=3265&AppID=84&AppType=Weblog&ContentType=0" width="1" height="1">
