#139396 - there is a 3rd byte Responding to: ???'s previous message |
thanks erik.
also, your code is defective in the respect that as it is it can not handle any frrequency >64kHz (counter overrun) When the counter reaches the maxium value (FFFFh) the interrupt should increase by 1 the 3rd extra-byte that I use to handle this. Are you sure? My idea is what you say, first timer to count 1 sec or less, and the other to count the frequency. As I said in my first post, now i'm not using the delay with a timer because I'm using the serial port. |

| the obvious way to do this is to use one timer as | 01/01/70 00:00 | |
