I am constructing an IC tester with micro-controller.
The IC i test for now is op-amp and 555 Timer, and later may be Digital Logic gate IC.
How should I synchronize all the different IC test by using micro-controller?
For example, different IC pin got different Vcc, GND, different input and so on.
What should I do to test these different IC with micro-controller?
Besides that, I am using window comparator for the testing output, the output voltage is 13-14V and 0V. What should I use to step down the voltage to 5V to fit in micro-controller? As I heard from some people may use High to Low shifter, is it ok?
