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)?
@vooiyap Ай бұрын
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.

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.

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

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.
