it would be awesome next video about watch dog timer implementation. You are my time savior. By the way, ı am translating your some videos into Turkish text to refer to when i forget the some points. :-)
@@embeddedsystemswitharmcort9051 I didn't post them anywhere online. I translated 16_Volatile Variables.odt, 12_System Timer.docx, 11_External Interrupts (EXTI).docx, 10_Interrupt Enable & Interrupt Priority.docx, 9_Interrupts.docx into Turkish as sentence by sentence. If you would like to see them ı can share with you.
Thank you for the lecture, Is there a mode, in which the timer starts counting as soon as an external event happens, and interrupts when the counter is overflowed? For example in order to acquire N data samples from ADC after the rising edge of a trigger signal occurred?
Hi, Mahdi, you can use EXTI to detect the tiger signal. In the EXTI interrupt handler, you can enable a timer. You can use the timer interrupt handler to perform ADC sampling. More efficiently, you can directly use the timer trigger output as the trigger input of ADC (so that there is no software involved for triggering ADC.)
Is this much quicker or more accurate than just using micros() at the start of a regular interrupt and comparing it to the previous micros()? I'm trying to compare signals that are up to 100 micros apart which is working about 95% of the time. Wondering if using the input capture interrupt would help or if I should try moving my project from and Uno to a Due. Thank you!
If a timer is enabled to capture multiple external inputs (we need to use multiple pins, with an input signal on one input pin), the timer interrupt is triggered whenever an event takes place on any input pin. In the timer interrupt handler, software should check the event status register to find which channel (or i.e., which input pin) captures an external event.
