 Before anyone accuses FIRST of being in the pocket of the sponsoring corporations, they might spend a minute and a half to actually apply some of that critical analytical ability that we are supposed to be demonstrating as educated engineers. - dlavery [more] |

Re: Micro Switch + PWM = Button?
This year, the driver station does not have pull-up or pull-down resistors on the digital inputs therefore they tend to float at an undefined state when no voltage (or ground) is applied.
Here's a diagram showing how switches connected to the Driver Station digital inputs can be connected successfully. Note, this does not necessarily apply to the cRIO digital inputs since they do have pull-up inputs. see here: http://www.chiefdelphi.com/forums/attachment.php?attachmentid=7369&stc=1&thumb=1&d=1 234143000 |
