- analog matrixIn/matrixOut are now mapped as floats from 0 to 1
- use of an external PRU code can be enabled with -P <filename>
- 16 channels of programmable GPIO can be accessed straight from render() either writing directly to the matrixGpio[] array or using digitalWrite(),
digitalRead(), setDigitalDirection() macros from Utilities.h .
