Thanks for the comment

[@stvarsoul]

hello, thanks for the video. It would be nice if you covered a video on the working of the ALE and how address and data buses are multiplexed for external memory access. Thanks once again.

[@PrinceRachitSinha]

Thank you professor! It was really helpful.

+Prince Rachit , Thank you Prince Rachit.!

[@reformedyouth350]

Thank you so much sir...!! actually it was a bit tricky topic but u made me understand it so easily...!

[@rohitkunta8328]

Good explanation 👍👍

[@vinjamurisaideepika7792]

Sir why didn't we add pullup resistor in case of port 0 as input when it has high impedance state

[@EnggClasses]

If you want me to cover any related topics, kindly let me know. I am happy to help and will upload the video at the earliest.
Thanks and Regards,

Hi sir,
With the same port 0 diagram, one buffer is connected at read pin, read latch, what is the significance of the buffer?

[@ejazalam7655]

Embedded system topic sir

I like this video...pls explain all other ports ....like this

[@noorbasha4553]

thank you sir, for brief explanation .i never seen in any books such explanation that you will do.

it was awesome.. bro!
keep uploading videos.. u teach very well

[@bhagyeshmodi2111]

very nicely explain and too helpful...keep uploading👏👏👏

[@kesavansalem]

What kind of software and stylus pen your using kindly send me. How you make this videos.

[@shashankshanbhag8529]

very nicely explained i was very confused as this is not provided in books and please i request you to upload for other microcontroller concepts thank u

[@EnggClasses]

+shashank shanbhag, Thank you so much Shashank, thanks for the appreciation.!

[@vidhitsamant4101]

nyc explanation sir..understood the concept finally of port 0 :)

[@shekharsachdev7710]

very nyc explanation sir ..helped me alot

Lucid explanation!!!

[@samudranag8706]

thank you so much sir....

[@EnggClasses]

Thanks for the reply.

[@abhishekm1903]

Excellent explaination.Thanks Sir,Can you please upload a tutorial on I2C Protocol

[@vipulsoman]

When Port 0 is as input both FETs are open(0) and point is at high impedance=>pull up resistor does not activate
When Port 0 is as output for 1 both FETs are open(0) and point is at high impedance => pull up resistor activates.
Both are same conditions which means when in input mode it should always input Vcc.
There's something wrong.

[@neerajprajapati5180]

Perfect explanations

[@muralidharandakshinamoorth849]

Thanks a lot sir, nice explanation

[@stanleyvictor6464]

Great Job Sir
Do keep up ur good Wrk

[@RealEyes24]

if I want to acces P0 is it right to do it like this ? P0 = 0x80, P1 = 0x90, P2 = 0xA0 and P4 = 0xB0 ?

[@swethaabraham4321]

at 2.53 you say that the external device can write a 1 value to pin at high impedance state.Is that so..shouldn't it be connected to external pull up resistors.

[@PriyanshGupta2906]

External pull-ups are for bringing 0 to 1 , in your case , you're already supplying 1 from an external device , hence no need for a pull-up resistor.

[@gauravjagdale3949]

Good !! Can you upload video on the Timers and the operating modes of timers of 8051 ?

[@lalitSharma-vh7jl]

can anyone tell me for using the port 0 of the microcontroller of 89s52 as the out put port we have to use the pull up resistors what should be the value of those resistors

pls, upload full video of i2c protocol...

[@joshuapinto7]

thanks a lot sir

[@EnggClasses]

+Joshua kar, Thank you Joshua.!

[@tailordhaval]

sir I have doubt when port 0 use as output port. When we want to send 0 , the lower FET in ON. At that time the pull up resister get ground so that at mid point we get 5V instead of 0. So i am confuse at that point.

[@kesavanram3657]

"port 0 as input" u giving 1 at D its ok, but "port 0 as output" u giving 1 at D which acts as input, then how can it act as output??????
