VexCode Sleep

Some examples have “Wait 2 seconds or 2000 milliseconds before starting the program.
vex::task::sleep( 2000 );”

I haven’t seen such examples, but there used to be a bug feature when 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 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:

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 configuration of the 3wire ports will not yet have completed.

[TVA:

Connor]Does the 3 wire ports initiate when the program is running and field control is disabled?

Three wire ports are configured just before main is called for those you have declared as global instances, but the configuration has to be sent to the internal micro controller that supervises them, so it will take some time, I forget exactly, perhaps 50mS.
