circuit analysis interview questions
the questions will depend on which engineering level you are applying and it depends on the level of design if it is circuit and systems or transistor level design.
if u r fresh graduated u have to review concepts.
behaviour of op-amp and feedback concept...
u can search the web about i2c
(first u have to understand it)
then write a code to implement it using pic or 8051
(both are good and easy, but u can write code for pic faster--i think that)
also u can note that some of micros have built in modules(hw) for i2c
first tied output ports of micro to inputs of component
then tied input ports of micro to the cresponding output pins of component
apply test vector (as input to component) and check the cresponding output vector
Re: sw real time clock
ok thanx all
but i think now i face another problem that
in case of sw hanging (the micro controller hangs for a while), how can overcome the difference between the sw time and the real clock(without reloading the current time).
thanx in advance
