1.We want to monitor the frequency of the signal which controls the timing of spark plug. Do anyone know from where to tap this anonymous signal and shape and V,I ranges? As it need not be sine wave we think about an external comparator(op-amp) to generate square.
2. And then we...
I am doing a project where i need to find the frequency of a waveform generated by a spark plug. I am using pic 16f 877a & ccs compiler for programming. As a beginning am trying to assume that the wavform to be measured is a sine. And convert it into an adc and make it square, & find the...
