Get Started With Embedded Systems - STM32 NucleoTutorial - Interrupts
5In this video I show you how to setup an external interrupt trigger using the inbuilt user button of a STM32 Nucleo dev board. This is useful to know because when developing embedded systems there can be multiple sensors on a board. These sensors can be setup to gather data before telling the micro-controller the data is ready. A sensor can tell a micro-controller that data is ready by sending an interrupt to the micro-controller. This allows the micro-controller to continue processing other data without having to keep checking if data is ready at a sensor because the sensor will let the micro-controller know.
When I started out I watched these tutorials to get an idea of what I was doing and they really helped me when I was starting out, 5 years into a career now I hope this video helps someone else who was in my position.
What would I say to my younger self?
Don't be afraid to google when figuring things out, don't worry about feeling like an imposter, and don't worry about asking too many questions!
