...code in one of the appropriate modules so you can see the degree of documentation. The added function reads two analogue inputs which are scaled half wave rectified mains signals, looks for the peak value and then multiplies this peak value with a third analogue input which is an input from a current sensor. The current sensor output is shifted so the zero current level is ~1.65v (~1/2 FSD of the DAC). The idea is to look for the direction of power flow (I x V) - if it is positive, we're have a high power threshold before resetting, if however it is negative the threshold is much lower, and the whole system must respond opening some relays within 20mS. Sampling interval for each of the 3 analogue inputs is of the order of 1mS, and is already in place. The complete project ...
