Hello everyone,
I'm designing a new system based on the STM32F746BET6.
Basically it's just reading and writing GPIOs and receiving/transmitting data through a few interfaces (ethernet and I2C). The system receives a 100 bit/sec data frame every second for time tagging (IRIG-B) and have to measure time width of every pulse received in order to decode the message (width of every pulse varies from 2 ms to 8 ms).
My idea is capturing every rising and falling edge with a timer and then calculating time difference in order to obtain the pulse with. Still, I have a few questions about it.
1) To do so, my system will get an interrupt everytime an edge is detected on my timer pin. Will this stop the uC from its tasks everytime an edge is detected?
2) Do I really need a timer to detect edges or is there some other way to get pulses width?
Thank you very much in advanced
