We could not have gone as far as we did without him. http://www.rcgroups.com/forums/showthread.php?t=1335765 Our plan was first to use thanhTran FinalProjectBlogpost.pdf sq7bti, oPossum, jsolarski and 1 other 4 Quote Link to post Share on other sites
oPossum 1,083 Posted May 7, 2014 Share Posted May 7, 2014 We were only able to drive one motor at a time, however, so if anyone has any suggestions on how we could do this please comment! Generate PPM with the MSP430, and then convert it to multiple PWM with a CD4017. http://forum.43oh.com/topic/1226-rcremote-can-also-be-used-to-control-8-servos/ Thanks for sharing your project! bluehash 1 Quote Link to post Share on other sites

petus 11 Posted May 8, 2014 Share Posted May 8, 2014 Very nice, can I share this project on the website http://chiptron.petus.cz. I will share it as "News" - a few sentences and link on this project :-) Quote Link to post Share on other sites

We will have to try that, we didn't even think about using an external IC to generate multiple PWM. Thanks! Quote Link to post Share on other sites
JBUKarl 4 Posted May 15, 2014 Author Share Posted May 15, 2014 @@JBUKarl Welcome! Does your university have a page for all your projects? Which course is this? Pretty cool. Thanks! Thanks!! This is for the course Embedded Systems, which at our university is basically a study of the msp430 and peripherals that can be used to make an embedded system. We have several of our classmates projects posted in this forum, but do not have a page for all of our projects together. Is there a way to link forum posts together? I believe our professor is pushing for a documented/organized display of our classes projects, so we will be moving that direction in the future, but as of now we do not have anything.

JBUKarl 4 Posted May 15, 2014 Author Share Posted May 15, 2014 Please correct links. s. Are all incorrect? unfortunately, we purchased some of our components from Ebay, which has a tendency to alter links and halt service. Hopefully you can still recognize the parts needed and be able to find them somewhere else? Quote Link to post Share on other sites

Hopefully you can still recognize the parts needed and be able to find them somewhere else? The first four looks like some web-mail referenced links. Just take a look at the beginning: https://mail.jbu.edu/owa/redir.aspx?C=f89ce17e5c8847cea19d0f2fb00cbfae&URL=http%3A%2F%2Fwww.ebay.com%2Fitm%2F10DOF-IMU-HMC5883L-ITG3205-BMA180-BMP085-Sensor-Module-For-MWC-Arduino-%2F321180164174%3Fpt%3DLH_DefaultDomain_0%26hash%3Ditem4ac7d4604e Great project by the way. s.
