You just have to make the interrupt edge trigerred and first interrupt come start timer and after second interrupt stop timer.For this with one pin only you have to make some hardware modification or find microcontrollers which give interrupts on both high-low or low-high edges.Simple 8051 gives only interrupts on high-low edges. so main program also get chance to finish. also read http://www.8052.com/forum/read.phtml?id=81237 |
