I'm using an accelerometer to measure velocity. So it's VERY important that I know the time between each measurement of the accelerometer. I have a 4MHz clock and I'm using CCS C compiler and my code is as follows: while( input(PIN_C2) ); // wait until low while( !input(PIN_C2) ); // wait until high while( input(PIN_C2) ) { // count high-time high++; } while( !input(PIN_C2) ) { // count low-time low++; } value = (float)high/(high + low); // calculate value Thanks, Shamoon |
