R4 Minima barebones direct-register code to use the DAC12 module in the RA4M1 processor.
Added DAC sine-wave example code using the RA4M1 hardware Floating Point Unit, which does speed things up!
Added test code for fast non-blocking ADC analog-read and DAC analog-write operation, with VERY-VERY-VERY fast sine calculation of frequency from ADC value.
Realtime sine calc with Paul Stoffregen's 11th order Taylor Series Approximation: https://www.pjrc.com/high-precision-sine-wave-synthesis-using-taylor-series/ Note: I have condensed the Taylor Series code to a single set of inline asm calls
