#145424 - PID whit 8052 Responding to: ???'s previous message |
I talk about the interruption that is detected by a change (1 to 0 or 0 to 1) .
In 8051 the interruption is detected for flank ascendent or descendent. In encoder signal A and B it is in different phase, so that if the interruption is detected by flank I lose information because no detect when A and B changes from 0 to 1 or from 1 to 0. |
