This is high level system architecture.

VEXCode get Run Time function? - #3 by jpearman

@jpearman

raw message rate for the inertial sensor is 50Hz. Three wire port (ADI) is 100Hz. Motor is 200Hz, but data is still only available to user code at 100Hz as explained by @hotel.
I’m very skeptical about the double integration being able to reproduce accurate results, but will be happy if someone can prove me wrong.

Defining three wire devices in text - #11 by jpearman

Move to separate RS485 entry later:

Smart Ports Power Wire

This is mainly aimed for @jpearman. Is there any way to provide power to a DC device through a smart port by taking a smart cable and splicing up one end? I’m trying to find a way to power LED lights from smart ports so that I don’t have to waste a legacy port.

You can already use VEXcode (and VCS) to interface to custom electronics using a smart port as a generic serial RS485 port. There’s only a C API at the moment, and little documentation, we will probably add a C++ API before next season. Contact me for more details and I can provide some sample code.

Help with Task Programming

The VCS/VEXcode scheduler is very similar to the ROBOTC scheduler. There are some differences due to the fact that ROBOTC was running as a virtual machine and had more control over when exactly the task switching could occur, however, the concepts are very similar. startTask( myTask ) becomes vex::task taskId( myTask ) wait1Msec(10) becomes task::sleep(10) AbortTimeSlice() becomes task::yield() and so on. (and I fixed the broken links in the original topic)

Trying to multitask in Vex Coding Studios for User Control

Here is some example code. It’s from VEXcode but should work in VCS as well. It uses additional tasks for drive and controlling a motor with one button. #include "vex.h" using namespace vex; // A global instance of vex::brain used for printing to the V5 brain screen vex::brain Brain; // A global instance of vex::competition vex::competition Competition; // define your global instances of motors and other devices here vex::motor leftMotor( vex::PORT1 ); vex::motor rightMotor( vex::P…
