It is said that 8051 has an on-chip oscillator but requires external clock to run it. What may be the internal circuit for on-chip oscillator, how it runs after connecting crystal oscillator? Also what is the purpose of external capacitor with crystal oscillator?
The problem with the professors in the collages and universities (i am talking with reference to state where i live) is that they dont have any practical knowledge (worst part).
They only read the theory books/reference books recommended by universities, to teach the particular subject. And some what knowledge that they have comes after few years of teaching the same controller.(sic) No point blaming any1. The issue needs to be brought into the authors notice. Atleast give it a try. :)
The esteemed colleges of rote learning seem to be churning out a lot of hapless programmers, we seem to have created a generation of professors and student incapable of thinking.
