Embedded Software Engineer Interview Question:

Explain me can we use printf inside ISR?

Submitted by: Muhammad
Printf function in ISR is not supported because printf function is not reentrant, thread safe and uses dynamic memory allocation which takes a lot of time and can affect the speed of an ISR up to a great extent.
