 Max TasksI have received an error indicating the maximum number of tasks is limited to 5... Is this correct?

Re: Max Tasks Yes, according to LoadBuildOptionsVEXIQ.h, it's 5:

Re: Max Tasks Is this something that is limited by the capabilities of the VexIQ brain?

Re: Max Tasks Yep - each task that's running needs it's own stack/call space. ROBOTC only has about 16KB of the 32KB of RAM available to us (VEX's 'master firmware' uses the rest for things like radio/I2C buffers). So if we were to leave a reasonable of memory for each task (approx 2K per task), plus the ROBOTC overhead, that affects the number of tasks/threads we can run.
The VEX IQ supports 5 tasks: 1 "main" and 4 "user" tasks. There is a bug in the current build that "main" isn't being counted by the compiler when it compile-time allocates memory for each task. |

Re: Max Tasks Ok, so if the individual tasks are very small and the total code size would remain under ~10k it shouldn’t present any problems… correct?
