teensylc branch/esp32 - calcTask() sometimes runs on core 0 and has lower refresh rate #102

calcTask() is created with "xTaskCreate" this means it can run on either core. If it runs on core 0 it competes with wifi and has a slower refresh rate, in my case 48 fps instead of 71 fps.

Instead the core should be select-able at run time or compile time using xTaskCreatePinnedToCore.
