Hello and welcome to my channel. My name is Vooi. I am a retired lecturer and my specialization is embedded systems. I am making a series of videos that are designed to help you understand embedded systems. The plan is, for a start, is to make a series of videos focusing on some fundamental knowledge. It is my hope these videos would lay a good foundation to understanding future videos related to embedded systems, especially, microcontrollers which are a key component of any embedded system. If you are interested in learning about embedded systems stay tuned to this channel.

Great teaching! Thank you!
@@laurenceo2340 Thank you
in the initSchedular(void) can you please explain the line, "task_list[i].task = (task_t)0x00". What's this 0x00 indicating by loacting just after the (task_t)?
Hi, the line task_list[i].task = (task_t)0x00; is initializing the task to a null or "empty" task, where the task doesn't point to any valid function. This ensures that the task scheduler won't try to execute a task that hasn't been properly defined yet. Later, valid tasks will be assigned, replacing this placeholder value. 0x00 is simply the hexadecimal notation for the value 0. Here, it is used to indicate that no function is assigned to this task initially.
@@vooiyap Thank you sir. I was not expecting your reply within just an hour. I really appreciate it.

Awesome 😎👍 I don't know assembly language But I love assembly Can you please make a video on "from where we can learn assembly language" Please Any book suggestions will also help
Hi, thank you for comments. As for learning assembly language. There are so many books on the subject and depends on the type of microcontroller/microprocessor. Do you have any type of microcontroller/microprocessor. in mind?

Very well explained Sir. I can now use my arduino uno to work with 8051 muc.
Hi, I am happy you got the circuit working. Have fun.
sir can i have this ppt for the learning purpose. ???
Hi, please send me your email address.
Very nice stuff, keep up the good work!
Hi thank you for your comments and support.
Hello, awesome lecture series and an equally awesome youtube channel which is very helpful for me! But when converting 10100011 into hex, after splitting, wouldn't 1010 be A and not 8? And so the hex number for 10100011 would A3. Same thing for the 16 bit binary number, where 1010 should be A and not 8, and so that 16 bit number would be E5A3 and not E583.
Hi, thank you for pointing out the error. I have added some text to rectify the error. I am glad that you still find the channel awesome. Thank you for your support.
Brilliant work Mr. Vooiyap

Is it possible to connect the LEDs to the negative supply instead of positive, so the ports aren't inverted?
Yes, it is possible to connect LEDs to the negative supply instead of the positive supply, and this can indeed prevent the ports from being inverted.

How can I choose a button on the numeric keypad and when pressed this button the value on the display increases from 0 to 1 and so on up to 9 and so on until returns to 0 again And choose a button on the numeric keypad and when this button is pressed, the value on the 7-segment display decreases from 0 to 9 and so on until it returns to 0 again as if it were a loop but a button must be pressed for the value to increase and another button to lower the value on the 7-segment display Like an example: If I pressed number 1 on the keypad the value incrises on the display of 7 segments and if I pressed number 4 the value decreases on the display of 7 segments Can you help me ?? Because I have seen many videos but I can't do a code to this problem
The solution involves capturing the key press, updating the value, and displaying the new value.
Hello, thanks for the content. Can we light two lcd's at the same time. Viewing number 1 in led 1, viewing number 2 in led 2 at the same time. Being able to see 12 in the 7 segment leds

Thank you for your comments.
256*256*70 = 4587520 cycles. Arduino UNO uses 16000000 Hz Crystal so : 16000000/4587520 = 3.487 seconds. This should be blinking freq. But in video it seems like 500 ms. Why is it so ?
Hi, to calculate the duration of the delay generated by an ATmega328 microcontroller using a 16MHz crystal, we need to take into account the time taken by each instruction and the number of iterations of the loops.

hello, can you pls explain why do we need to set up stack, can't we just use interrupts without stack?
Interrupts and the stack are fundamentally linked in the context of microcontroller operations. The stack is essential for handling interrupts efficiently and ensuring that the program can return to its normal execution flow after an interrupt service routine (ISR) has completed.
Very detailed information, thank you
You are most welcome
very good content, also the presentation! Many thanks!
