![]() Since this is about using interrupts specifically, a single pin on the Arduino is dedicated to triggering an interrupt on these edges. ![]() To make sure the data is decoded properly, the first thing to set up is edge detection on the incoming signal. ![]() This data is usually transmitted as audio, so the response from the microcontroller needs to be quick. But if you want to dig into them, they’re still working underneath everything as shows us in this last of a series of posts about interrupts.įor this how-to, is decoding linear timecodes (LTCs) at various speeds. This has opened up affordable microcontrollers to people who might not be willing to spend hours or days buried in datasheets, but it has also obscured some of those useful lower-level functions. Arduinos have been the microcontroller platform of choice for nearly two decades now, essentially abstracting away a lot of the setup and lower-level functions of small microcontrollers in favor of sensible IDEs and ease-of-use.
