#84143 - Half bits Responding to: ???'s previous message |
The trick is to measure in the middle of the bit, not the edge.
After the start bit, set the timer to time out to the center of the first bit. Then do full bits. Measuring near the edge means you and the sender must have perfect clocks. Do not forget to error check. if you are ignoring the start and stop, you will never resync if you get a glitch. |
