+Ksarul #26 Posted November 2, 2020 I'll try and go through all of these tomorrow. Yes--there are some interesting differences that make sense to be opposite (I think TI was taking a signal that was considered to be a normal low and inverting it to get a high input) 1 Quote Share this post Link to post Share on other sites

Yes, please download all 3 zip files again, these are the latest...but some files are the same as before, just changed the dates to keep track of the files. Also the Corcomp DSDD files U1&U2 are for the controller with the WD2793 chip. The zip has been updated. Edited April 3 by Fritz442 1 1 Quote Share this post Link to post Share on other sites

+Ksarul #45 Posted April 4 Thanks for the datasheet, Doug. I have a bunch (at least 200) of the 1052911-X chips too, so we definitely have enough of them in the community to support a project using them. . . 2 Quote Share this post Link to post Share on other sites
