Clear explanations, neat drawings & writings topped by logical explanation is all this lecture is all about. Never seen any lecturer explain things in details like this.🙏🙏🙏🙏
well, i have been followed this prof since intro to 8085 lecture.so it had really been helpful in understanding the microprocessor n other .so i must say u are mine best youtube lecturer n thank u for everythng .i m looking forward 4 more video from u.
In theory this is all very fine but I am having the oddest weirdest funniestphenomenon with the 8251 UART. Its system clock is 2Mhz. Asynchroneous transmission works perfectly with 15625, 28800, 62500 baud and some other values which is decided by a separate Arduino square wave TTL oscillator which can be programmed continuously between 31hz and 65Khz. So there's no issues with the RxTx clock. It is below 4.5 fclock8251 as demanded by the specs. This works for both sync and async transmission according to the specs. I can program the Arduino at different speeds and it effectively produces the frequencies I mentioned above. The phenomena is that the 8251 pertinently refuses to transmit the data proparly at 31250 baud. It garbles. I would like you guys to produce this phenomena in your class lab or at home. Use 2Mhz as 8251 system clock and use a lab or other oscillator to produce the TxC clock. Make sure to use different frequency settings between say 400hz and 64Khz and observe how the 8251 produces the data stream. Let me know if your 8251 succesfully produces correct serial data at the TxD line at several randomly chosen TxC frequency. Especially when TxC is 31250. This is very important because the fenomena I experience is with several 8251 chips I have exactly the same as described above. Let me know your results asap.

USART starts from 35 min onwards..
Thank you bro !!!!
thank you

great video! a GEM!
Pertfect
Very good class. Lots of basics. Thank you Sir.
i guess it is quite off topic but does anybody know a good website to watch newly released movies online ?
@Matias Ali Flixportal =)
@Joel Jax thank you, signed up and it seems like they got a lot of movies there :D Appreciate it !!
@Matias Ali Glad I could help :D
gr8 lecture sir ... thank u so much
nice sir ji....
merci boucoup
thanks
niceeee
without subtitle I can hardly followed the professor's saying.
it is really difficult to follow the pronounciation of the professor.
LIWEI PENG Have you ever heard a Chinese professor?
