Vex Coding Studio Gyro endless counting

[technik3k]

First of all, make sure that the wire is fully inserted into 3-wire port and connected to the Gyro with proper polarity (black wire is Ground).

Then try to change your preauton as follows and see if it helps:

void preauton()
{
  vex::task::sleep(300);
  Gyro.startCalibration();
  while(Gyro.isCalibrating())
  {
    vex::task::sleep(1);
  }
}

V5 has a quirk, where reading values of sensors, connected to legacy 3-wire ports (analog and digital), were returning 0 if you try to read them right after V5 startup.

So if you are trying running autonomous right after program starts you would need to delay reading those sensors for a short period of time to let it properly initialize.

More details are in this topic:

v5 delay on reading 3-wire

yes, actually the same situation. When a program is run we don’t initially know what each 3wire port could be. The program configures them right at the beginning of the code, if they are read and the configuration has not yet finished (it can take some time) we probably just return 0 if you try and read them. If no competition switch is connected the usercontrol task will be started at more or less the same time as main (slightly after it), so yes you will see the situation you describe as c…
