How fast can the interrupt be responsed?
2005-11-18 12:10 AM
I use 1 pin as external input, and want it interrupts on rising edge?
when i give it a 8k pulse,it works well ,but when the signal frequency is 9khz, it doen't come in my interrupt handler routine anymore, can you have any way to solve it ? or give me a limit?
