1. AQA Programming Languge

   • Outputs / Inputs
     • To setup which ports are input/output ports you have to define them at the start of the code.
       • MOVW 0x00 MOVWR TRISB
       • 0x00 is 0 so sets all ports low and outputs
       • To set all ports to inputs you'd use 0xFF which 255
     • (MSB) 128(D7) 64(D1) 32(D1) 16(D1) 8(D1) 4(D1) 2(D1) 1(D0) (LSB)

2. DAC - Digital to Analogue Converter

   • Equation - "-Vout = Rf [v1/r1+v2/r2+v3/r3 ...]"
   • Used for mixing music or adding logic signals
   • R3 in diagram always equals Rf. R3 is also MSB
