/*PIN ALLOCATIONS
RA0 - Debuggin LED
RA4 - MTRCSN (Motor SS/GPIO pin)
RB2- MTRSI (Motor serial in)
RB3- MTRSCK (Motor clock)
RC3 - SCLK (for both temp and humidity I2C)
RC4 - SDA (I2C data for both temp & humidity)
RC5 - MTRSL (Motor serial out)
RC6 - RX (Receiving)
RC7 - TX (Transmitting to ESP 32)
