Hi. When counting pulses using a microcontroller (say from an encoder or pulse generator), there are two methods: polling and using interrupts. Two alternative designs can be used (well, at least), one is to have the Microcontroller do it directly, and the other is to use a dedicated chip to do it. The concern is of course that the microcontroller might miss pulses if it is loaded with other tasks.
So which method is prefered? Any suggestions?
Thanks
