This application utilizes timer 2 to generate a 1-second time base, resulting in an interruption being generated every second. This interrupt calls the custom period elapsed callback function, which sets the periodElapsed flag. This flag is used in the infinite while loop in the main function. ...
Next we have to enable the interrupt for EXTI0 on the processor side. We do this by setting the appropriate bit in the Interrupt Set-enable register. So we just before enabled the interrupt on the microcontroller peripheral side. Now in order for the processor to take in the interrupt,...

How to manage dynamic power in a microcontroller using its non-maskable interruptAjit BasarurShantanu Prasad Prabhudesaiand Nazmul HodaIttiam Systems
In short, if your program is iterating over a 1000 character string using a for-loop, it won't stop until it reaches the end. However there are two things: With interrupts active ( In Arduino they default to on - allowing timers to work etc.). So in the background an interrupt wi...
A possible solution can be to implement, for example, a RAM test on a part of the RAM that is currently not in use, while the application is temporarily redirected to use another part of the RAM that does not overlap with the tested area. 4.2 No co...
This is how you can organize the firmware of the microcontroller for the best performance: the time-critical tasks are grouped in the interrupt loop, while the time-non-critical tasks are grouped in the background loop. After the system is initialized, the central processing unit goes into an...
Part Number: MSP430FR2433 Dear experts, i have working with interrupt example here i have used two pin in same port but i can't find which pin interrupt occurred
I don't fully understand what all is going on in the timer example I found but I'm sure it does what I want. The example is msp430x21x2_ta0_22.c It is also good to know that no other interrupts will occur once an interrupt is granted until the GIE is set again. ...
We also need to update the vector table used by the microcontroller. The vector table contains the address of every exception and interrupt handler in our system. When an interrupt signal comes in, the ARM core will call the address at the corresponding offset in the vector table. For example...
