You madam helped me understand this for a semester exam easily!
This question is actually asked in most of previous year papers!
Thank you subbed easy explanations keep them coming!
Really good and easy to understand presentation, especially for a beginner like myself. The real world examples were a nice addition!
Glad it was of help!
Our mind's innate inquisitivenss has made things possible once even unimaginable. Keep up the good work by putting up such information which can ignite brighter tomorrow.
Thank you!!
best introduction to watchdog timer, very grateful🙏
Crazy good! You didn't had to go so hard !
Thank you very much for your microcontroller basics playlist! It was invaluably helpful to me.
Thank you for this video. Very clear explanation of watchdog. Now I will check the link because I want more information about types of watchdogs
Love your work, Simple and easy to understand.
Superbly explained.. great work!!
Thank you !!
wow nice combination Realtime examples with concepts.
Thank you m'am!
Nice thanks for the good explanation!
very well done. Cheers
Good Examples
My LCD do display corrupted characters upon several transition probably bcs of length of cable to LCD or electrical interference. So most times I does manual reset or switch the circuit off and on to restart. Pls how do I use WDT to restart the MCU when it goes into another mode.
Thank you for explaining with real world examples. One question, if the code can be uploaded/ updated remotely, what are the safeguards to ensure that only authorised code is uploaded to the controller?
That's an interesting question and as far as I know it is possible to break into the system but the question is will it be worth it given the cost and effort needed to accomplish the same...
Are there any software implementations of watch dog timer ? Or it is always at hardware level ( considering the example provided in the video)
Software-based wdt can be implemented. It all depends on the system under consideration!
Today i understood the exact function of wdt😅
Mam is it possible to trigger (whenever any pin connected to the controller, that pin used as a feeding signal to the watchdog) the watchdog timer externally.
Like Manual hardware trigger.
how do you intend to use it? Also, check the datasheet!
