#184476 - us, not ms Responding to: ???'s previous message |
An ISR should try to get the required job done within a number of microseconds - not milliseconds.
Remember that even at a paltry 9600 baud, a UART will receive one new character every millisecond. And there are often many other functions in an embedded system that must be processed reasonably quickly. So delays in an ISR should only be to get the required amount of settle and hold times when communicating with external equipment. Internally, there shouldn't, normally, be a need for any delays. |
