However, if two or more occur (of the same vector) you will lose information. With quadrature you need to insure your interrupt latency (i.e. duration that interrupts are disabled) is less than your minimum time between quadrature interrupts. 2000/sec is very slow, however. I rou

Luke: the latest WinAVR compiler has removed all references to "inp" and "outp" You can replace this with direct PORT references. E.g. SomeVar = inp(PINB); change to: SomeVar = PINB; Or if you want, do this in the AvrX header file (or some other place) #define inp(A) (A) #define

Richard, I have not programmed a 'mega32, but have used the 16 bit timer on the tiny2313. It appears that you are incorrectly programming the timer as an 8 bit timer. Timer1 is 16 bits. This may be your problem (or I may be way off base). Best regards, Paul H. --- In AVR-Chat@yah
