Delphis MU-Submarine
We evolved a 2-bit DAC design to control our servomotors. What
originates as a 2 bit control word must be converted to left,
center & right as per the truth table mentioned below. The DAC
O/P would be either 3.5, 5 or 6.5V. This analog voltage is
given as input to a 555 timer circuit that produces the
corresponding PCM control signal for the servomotors.
