anyone out there who can help me write a program to decode a waveform?... i have a series of 1s and 0s from a TTL voltage eg 101010100101001101010 and they are coded in 5bit frames ie 10000= decimal 1 ( there are abt 15 characters, total of 75 bits) problem is how do i use the capture mode to pick up the signal of the high and low voltages( high(5v)=0, low(0v)=1) and put them into a string. im using a low end magnetic swipe card reader, signal to 8052
